TY - JOUR AB - Fenton's reagent (Fe2+/H2O2) is known as one of the most effective and most often employed advanced oxidation process (AOPs) for the treatment of textile dyes and dyehouse effluent. In the present study, a synthetic acid dyebath effluent (SADB) bearing two azo and one anthraquinone dye together with two dye auxiliaries was subjected to pretreatment with Fenton's reagent. Firstly, initial Fe2+ and H2O2 concentrations as well as pH were optimized to achieve highest COD and color removals during Fenton's treatment of SADB. In the second stage of the experimental work, kinetic studies were conducted to elucidate the effect of operating temperature (20 °C < T < 60 °C) on COD, color abatement and H2O2 consumption kinetics. Obtained results indicated that 30% COD and practically complete color removal (99%) could be achieved at T = 50 °C. The kinetic studies revealed that a strong correlation existed between COD removal and H2O2 utilization rates. In the final part of the study, the acute toxicity of raw (untreated) and pretreated SADB on heterotrophic biomass was investigated employing a modified (COD-balanced), activated sludge inhibition test. The toxicity experiments demonstrated that the inhibitory effect of SADB towards sewage sludge could be completely eliminated when the effluent was pretreated with Fenton's reagent.

Daphnia magna was used to test acute toxicity in raw and pre-treated wastewater. The operational parameters for each process were determined on the basis of complete toxicity removal. The FO process removed COD at a higher rate (59%) than O3 (33%) while colour removal was similar (89% and 91%, respectively). The CF process removed both COD and colour at rates similar to the FO process. A colour range of 150–250 platin–cobalt (Pt–Co) unit was assessed for toxicity.

Box–Behnken statistical experiment design and the response surface methods were used to investigate the effects of simazine, H2O2 and Fe (II) concentrations on simazine degradation and mineralization. Total organic carbon (TOC) and simazine removals were investigated at different reagent doses to determine the experimental conditions yielding the highest removal of simazine and TOC. Fe (II) concentration had more profound effect than H2O2 for simazine removal while all parameters affected mineralization (TOC removal). Complete disappearance of simazine was achieved within 6 min reaction period. However, only 32% of simazine was mineralized after 15 min indicating formation of some intermediate products. The optimal H2O2/Fe (II)/simazine ratio resulting in the maximum pesticide (100%) and TOC removal (32%) was found to be 55/15/3 (mg L−1). The initial rate of simazine degradation was found to be first-order with respect to the initial simazine concentration.

Box–Behnken statistical experiment design was used to determine the effects of reagent concentrations on amoxicillin degradation and mineralization. Amoxicillin (10–200 mg L−1), hydrogen peroxide (10–500 mg L−1) and Fe(II) (0–50 mg L−1) concentrations were considered as independent variables in batch oxidation experiments. Percent amoxicillin and total organic carbon (TOC) removals (mineralization) were considered as the objective functions to be maximized. Required reaction times were 2.5 min and 15 min, respectively for degradation and mineralization of amoxicillin. Both peroxide and amoxicillin concentrations affected the extent of amoxicillin degradation and mineralization. Complete amoxicillin degradation was obtained within 2.5 min while 37% mineralization took place within 15 min. The optimum peroxide/Fe/amoxicillin ratio resulting in complete amoxicillin degradation and 37% mineralization was 255/25/105 mg L−1.

Significant drop in COD removal has been observed. Optimisation of process parameters like pH, temperature, H2O2 and FeSO4 has been done. Temperature and pH played a key role in this treatment process, in addition the process initially liberated heat due to reaction between FeSO4 and H2O2. From the experimental results it has been observed that with increasing FeSO4 and H2O2 concentration the degradation of waste increases. At an optimum concentration of FeSO4 (6 gm/l) and H2O2 44.40 gm/l reduced 60% COD, whereas 220gm/l H2O2 was required for 95% COD removal. To reduce cost and the H2O2 concentration for maximum waste degradation, Fenton's oxidation process followed by biochemical treatment was tried at same experimental condition. The treatment enhanced the overall removal efficiency of COD, BOD, salinity and colour significantly. The microbial treatment by Thiobacillus ferrooxidans, following Fenton's reagents treatment, showed that the COD reduction has reached to about 97% compared to 60% with Fenton's reagents and 17% with T. ferrooxidans alone in 24 h, showing the synergistic effect. Thus the combined treatment results indicate the possibility to minimize the Fenton's reagents without compromising the efficiency of the process but ultimately reducing the overall treatment cost. This study seems to be very much important and economical by reducing the required H2O2 amount to about five times using a suitable micro-organism. This hybrid treatment system showed 97% COD reduction can be achieved within two days.

Water is perhaps our most valuable resource, and thus should be recycled. Many of the current recycling techniques for polluted water only concentrate the pollutant without degrading it or eliminating it. In this sense, advanced oxidation processes are possibly one of the most effective methods for the treatment of wastewater containing organic products (effluents from chemical and agrochemical industries, the textile industry, paints, dyes, etc.). More conventional techniques cannot be used to treat such compounds because of their high chemical stability and/or low biodegradability. This article describes, classifies, and analyzes different types of advanced oxidation processes and their application to the treatment of polluted wastewater. AU - Poyatos, J. M. AU - Muñio, M. M.

The experimental results revealed that under the optimum Fenton oxidation conditions (initial pH 5, H2O2 dosage 17 mmol/L, and Fe2+ 1.7 mmol/L) the average total organic carbon (TOC) and color removal ratios were 39.3% and 69.5% after 35 min of reaction, respectively. Results from Zahn-Wallens Test also represented that Fenton process was effective to enhance the biodegradability of the test wastewater. As for the further purification of MBR process, TOC removal capacity was examined at different hydraulic retention times (HRT) of 10, 18 and 25 hr. Under the optimum HRT of 18 hr, the average TOC concentration and color of the final MBR effluent were 16.8 mg/L and 2 dilution time, respectively. The sludge yield coefficient was 0.13 g MLSS/g TOC and TOC degradation rate was 0.078 kg TOC/(m3·day).

In this study, the variables considered for the process optimisation were the hydrogen peroxide and ferrous ion initial concentrations and the temperature, for an antibiotic concentration of 450 μg L− 1 at pH = 3.5. This methodology also allowed assessing and identifying the effects of the different factors studied and their interactions in the process response. An appropriate quadratic model was developed in order to plot the response surface and contour curves, which was used to perform the process optimisation. From this study, it was concluded that ferrous ion concentration and temperature were the variables that most influenced the response. Under the optimal conditions (hydrogen peroxide concentration = 3.50–4.28 mg L− 1, ferrous ion concentration = 254–350 μg L− 1 and temperature = 20–30 °C), it was possible to achieve total amoxicillin degradation after 30 min of reaction.

Chelated heavy metal containing wastewater needs to be treated not only for the toxic heavy metal, but also for the chelating agent. The treatment of strong stability chelated heavy metal wastewater is a hot and difficult issue in these years. To solve this problem, a novel strategy, advanced Fenton-chemical precipitation process (AF-CPP) is proposed to address chelated heavy metal containing wastewater. The process uses zero-valent iron and hydrogen peroxide for degrading the chelated compound, followed by alkali precipitation of heavy metal. NiEDTA was selected as a model of strong stability of chelated heavy metal pollutant. This process can remove not only nickel ions, but also reduces COD values. Parameters affecting nickel removal are discussed. At optimum condition, the nickel removal efficiency attained was 98.4% and the residual concentrations of nickel fell below the value stipulated in Integrated Wastewater Discharge Standard of China (GB8978-1996). AF-CPP appears promising and effective for the treatment of strong stability chelated heavy metal containing wastewaters.

The operating conditions (temperature as well as ferrous ion and hydrogen peroxide dosage) have been optimized. Working at an initial pH equal to 3.0, a Fe2+ concentration of 200 mg/L and a H2O2 concentration to COD initial weight ratio corresponding to the theoretical stoichiometric value (2.12), a TOC conversion higher than 45% at 25 °C and 60% at 50 °C was achieved. Application of the Fenton oxidation process allows to reach the COD regional limit for industrial wastewaters discharges to the municipal sewer system. A simple kinetic analysis based on TOC was carried out. A second-order equation describes well the overall kinetics of the process within a wide TOC conversion range covering up to the 80–90% of the maximum achievable conversion. AU - Bautista, P.

However, no general recommendations of universal validity could be made in the term of optimized conditions affecting Fenton process. At the first stage of this study, collected leachate samples from Aradkooh site, Tehran, Iran, were investigated using one-factor-at-a-time method to find out optimum coagulation pH and flocculation time values. Subsequently, the obtained results in addition to data issued previously by the authors were employed to develop a predictive model of the true response surface, namely chemical oxygen demand (COD) removal efficiency. Finally, the main parameters of Fenton procedure, i.e. initial pH, [H2O2]/[Fe2+] molar ratio, Fe2+ dosage, and coagulation pH were optimized taking advantage of the above-mentioned quadratic model. The derived second-order model included both significant linear and quadratic terms and seemed to be adequate in predicting responses (R2 = 0.9896 and prediction R2 = 0.6954). It was found that the interaction between initial pH and Fe2+ dosage has a significant effect on COD removal. While, the optimal [H2O2]/[Fe2+] molar ratio was independent of ferrous ion dosage. The optimum conditions for the maximum COD removal of 50.76% for the parameters of initial pH, [H2O2]/[Fe2+] molar ratio, Fe2+ dosage, and coagulation pH were found to be 5.8, 8.0, 22,500 mg/L, and 8.7 respectively.

The ratio of hydrogen peroxide-to-Fe(II) (x1) was between 1.67 and 8.33. Fe(II) concentration was constant at 0.03 M while the H2O2 concentration was set at three levels: 0.05, 0.15 and 0.25 M. Based on the molarity ratio, the selected ratio were in the low range of Fe(II)-to-H2O2 ratio (≪1). While based on the wt/wt ratio, the tested Fe(II)-to-H2O2 ratios were in the range of ≤1:5. pH (x2) was between 3 and 5. The concentration of OMW (x3) was varied between 40 and 100%. The influence of these three independent variables on the four dependent variables, i.e. COD, total phenolics (TP), color and aromatocity removal was evaluated using a second-order polynomial multiple regression model. Analysis of variance (ANOVA) showed a high coefficient of determination (R2) value of 0.902–0.998, thus ensuring a satisfactory adjustment of the second-order regression model with the experimental data. H2O2-to-Fe(II) ratio had significant effect on all the four dependent variables. The positive sign for the regression coefficient of this regressor variable indicated that the level of the pollutant removal increased with the increased levels of factor x1 from 1.67 to 8.33 and this effect was the most pronounced for TP removal. pH had also significant effect on the pollutant removal and the effect was the most noticeable for TP reduction. The negative coefficient of this variable (pH) indicated that level of the pollutant removal decreased as the pH increased from 3 to 5. The negative coefficient of the interaction between variable x1 and x2 indicated that a simultaneous increase in H2O2-to-Fe(II) ratio with decrease in the pH of the reaction led to an increase in the COD, TP and color removal. Quadratic models were predicted for the response variable, i.e. pollutant removal, and the maximum model-predicted removals were 56, 100, 33 and 32% for COD, TP, color and aromatocity, respectively. Optimum conditions for this wastewater treatment was obtained based on the performance of the Fenton's peroxidation in the experiment where the H2O2-to-Fe(II) ratio was at its high level (8.33) and the pH and OMW concentration were 4 and 70%, respectively.

Traditional metal ion treatment processes such as chemical precipitation generate large volumes of toxic sludge which needs to be further solidified or disposed of. The ferrite process (FP), which is another effective approach of treating metal ion-containing wastewater, can crystallize metal ions into ferrites; the sludge easily precipitates, is stable and can be recycling. This investigation explores the feasibility of the Fenton process and the FP (FFP) for treating wastewater that contains metal ions. It considers one factor that adds noise to the FP, ethylenediaminetetraacetic acid, and establishes the optimum parameters of each procedure. The analytical results demonstrate that the proper conditions for Fenton process were pH = 2, [Fe2+] = 10−2 M, H2O2 dosing rate = 5 × 10−4 mol min−1, reaction time = 12 min. For the proposed multi-stage FP, the preferred Fe2+ dosage was 0.098 mol in each stage and the sludge met the toxicity characteristic leaching procedure standards. Following the FFP, the effluent water or the sludge easily met Taiwan’s standards. Finally, the SEM test demonstrated that size of the sludge particles was 50–110 nm.

After hydrogen peroxide oxidation, the refractory organic substances in wastewater were decomposed. COD, offensive odor and foaminess in the effluents were reduced with increasing dose. Hydrogen peroxide oxidizes both organic and inorganic pollutants which contribute to BOD and COD. The Oxidation of sulfides into sulfates by H2O2 may be applied directly to aqueous wastes containing these odorants. Inactivation efficiencies of bacteria in the secondary effluents by H2O2 oxidation was investigated. The number of total coliforms exponentially decreased with increasing dose and fell to low levels at the dose of 2.5 ml/L.

An initial phenol concentration of 100 mg/L was used as representative of a phenolic industrial wastewater. Working temperatures of 25 and 50 °C were tested, and the initial pH was set at 3. The H2O2 and the Fe2+ doses were varied in the range of 500?5000 and 1?100 mg/L, respectively, corresponding to 1?10 times the stoichiometric ratio. A series of intermediates were identified, corresponding mainly to ring compounds and short-chain organic acids. Most significant among the former were catechol, hydroquinone, and p-benzoquinone; the main organic acids were maleic, acetic, oxalic, and formic, with substantially lower amounts of muconic, fumaric, and malonic acids. Under milder operating conditions (H2O2 and Fe2+ at lower concentrations), a great difference was found between the measured total organic carbon (TOC) and the amount of carbon in all analyzed species in the reaction medium. This difference decreased as the doses of H2O2 and Fe2+ increased, indicating that the unidentified compounds must correspond to oxidation intermediates between phenol and the organic acids. To establish a complete oxidation pathway, experiments were carried out using each of the identified intermediates as starting compounds. Dihydroxybenzenes were identified in the earlier oxidation stages. Muconic acid was detected in catechol but not in the hydroquinone and p-benzoquinone oxidation runs; the last two compounds were oxidized to maleic acid. Oxalic and acetic acid appeared to be fairly refractory to this oxidation treatment. A detailed knowledge of the time evolution of the oxidation intermediates is of environmental interest particularly in the case of hydroquinone and p-benzoquinone because their toxicities are several orders of magnitudes higher than that of phenol itself. The time evolution of the intermediates and TOC was fitted to a simple second-order kinetic equation, and the values of the kinetic constants were determined. This provides a simplified approach useful for design purposes. AU - Zazo, J. A. AU - Casas, J. A. AU - Mohedano, A. F. AU - Gilarranz, M. A. AU - Rodríguez, J. J.

Techniques applied included catalytic wet air oxidation (CWAO) over active carbon (AC) alone and with hydrogen peroxide (H2O2) as well as wet peroxide oxidation (WPO) without or plus Fe2+ initiator. The oxidation tests were conducted in a Trickle Bed Reactor and a tubular coil reactor at 25–550°C and 10–150 bar. The refractoriness to chemical wet oxidation was investigated for various organic pollutants including phenol, o-cresol, m-xylene, o-chlorophenol, p-nitrophenol, aniline, nitrobenzene, sulfolane and two industrial phenolic wastewater. CWAO over AC destroyed readily phenol, o-cresol, m-xylene and o-chlorophenol at 140°C and 9 bar of O2. More refractory aniline, p-nitrophenol, and particularly sulfolane and nitrobenzene, were tested with either H2O2 promoted CWAO or WPO at higher temperatures. The use of Fe2+ initiator was attempted to reduce the treatment severity of WPO. In a final step, the wet oxidation techniques were tested on the industrial effluents to obtain treatment efficiencies under field conditions. AU - Stüber, F. AU - Font, J. AU - Eftaxias, A.

Experiments were conducted on the samples containing 100 and 200 mg l−1 of RB5 to remove the dye toxicity. Seventy-five milligram per litre of RB5 caused 25% toxicity on 24-h born daphnids whereas 100 mg l−1 of RB5 displayed 100% toxicity on Daphnia magna. The study was performed in a systematic approach searching optimum values of FeSO4 and H2O2 concentrations, pH and temperature. Optimum pH and temperature for 100 mg l−1 of RB5 were observed as 3.0 and 40 °C, respectively, using 100 mg l−1 of FeSO4 and 400 mg l−1 of H2O2 resulted in 71% chemical oxygen demand (COD) and 99% color removal. For 200 mg l−1 of RB5, 84% COD removal was obtained using 225 mg l−1 of FeSO4 and 1000 mg l−1 of H2O2 yielding 0.05 molar ratio at pH 3.0 and 40 °C. Color removal was also more than 99%. The optimum conditions determined in accordance with the literature data. The H2O2 requirement seems to be related to initial COD of the sample. FeSO4/H2O2 ratios found were not changed for both concentrations. The temperature affected the COD removal significantly at high degrees. Toxicity was completely removed for each concentration of RB5 at optimum removal conditions.

In this context, Advanced Oxidation Processes (AOPs) are considered a highly competitive water treatment technology for the removal of those organic pollutants not treatable by conventional techniques due to their high chemical stability and/or low biodegradability. Although chemical oxidation for complete mineralization is usually expensive, its combination with a biological treatment is widely reported to reduce operating costs. This paper reviews recent research combining AOPs (as a pre-treatment or post-treatment stage) and bioremediation technologies for the decontamination of a wide range of synthetic and real industrial wastewater. Special emphasis is also placed on recent studies and large-scale combination schemes developed in Mediterranean countries for non-biodegradable wastewater treatment and reuse. The main conclusions arrived at from the overall assessment of the literature are that more work needs to be done on degradation kinetics and reactor modeling of the combined process, and also dynamics of the initial attack on primary contaminants and intermediate species generation. Furthermore, better economic models must be developed to estimate how the cost of this combined process varies with specific industrial wastewater characteristics, the overall decontamination efficiency and the relative cost of the AOP versus biological treatment.

Chemical Fenton technology was tested using commercial 30–35% solutions of H2O2 and iron (II) salts, which was followed by the additional electrochemical destruction of organic pollutants in an undivided reactor with catalytic stable anodes (CSA) and 1 g L−1 NaCl as a supporting electrolyte and a source of active chlorine. An alternative electrochemical method involving the electrogeneration of hydrogen peroxide in polluted water at the gas -diffusion cathode was studied both with the addition of ferrous salt to the electrolyte prior to electrolysis (in-cell electro-Fenton) as well as with the post-electrolysis addition of Fe2+ in another reactor (ex-cell electro-Fenton). The accumulation of hydrogen peroxide in concentrations sufficient for the mineralization of organic pollutants was achieved in both cases with near 100% current efficiency. In comparison with wastewater treatment processes which use a purchased hydrogen peroxide reagent, the Fenton-like processes achieved an economic savings of as much as 64.5% in running costs due to the on-site electrochemical generation of H2O2. Preparative electrolysis in the membrane reactor showed higher current efficiencies and lower specific energy consumptions for H2O2 electrogeneration in comparison with the results of tests carried out in an undivided cell.

Acid Black 1, under neutral conditions. The effects of different system variables namely initial concentration of Fe2+ or Fe3+, initial concentration of H2O2, initial pH of solution and reaction temperature were studied. Dye degradation in Fenton oxidation was faster initially than Fenton-like oxidation but the extent of degradation achieved for the two systems was similar after 100 min. The kinetics of Fenton oxidation is complex and can be described by a combined pseudo-first-order kinetic model while the Fenton-like reaction follows comparatively simpler, pseudo-first-order kinetics. The apparent reaction orders regarding Fe and H2O2 concentrations for the two systems were similar, with values of 3 and 0.7, respectively. The degradation rate was strongly dependent on the initial concentration of Fe2+ or Fe3+, the initial concentration of H2O2 and initial pH. Maximum degradation rate was achieved at optimum concentrations of Fe and H2O2 as well as solution pH. The reaction temperature (15–45 °C) had little effect on overall dye oxidation rate in the Fenton-like reaction.

The best operating conditions for treatment of antibiotic aqueous solution containing 104, 105 and 103 mg/L of amoxicillin, ampicillin, and cloxacillin, respectively were: Fenton process — COD/H2O2/Fe2+ molar ratio 1:3:0.30 and pH 3; photo-Fenton process — COD/H2O2/Fe2+ molar ratio 1:1.5:0.075 and pH 3; UV/TiO2/H2O2 process — TiO2 1 g/L, ambient pH ∼ 5 and H2O2 100 g/L; UV/ZnO process — ZnO 0.5 g/L and pH 11. All studied processes were able to degrade the antibiotics and improve biodegradability (BOD5/COD ratio), except for UV/ZnO process which did not improve biodegradability. Photo-Fenton process exhibited higher rate constant (0.029 min− 1) than that of Fenton process (0.0144 min− 1) and this may be ascribed to photochemical regeneration of Fe2 + ions by photoreduction of Fe3 + ions and hence increasing hydroxyl radical production rate. Rate constants of UV/ZnO process (0.00056 min− 1) and UV/TiO2/H2O2 process (0.0005 min− 1) were lower than that of Fenton and photo-Fenton processes. Photo-Fenton process appeared to be the most cost-effective compared to the other studied processes. AU - Elmolla, Emad S.

In this review article, the fundamental principles and governing factors of Fenton oxidation for treating soils contaminated with POPs such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), are firstly discussed. Current practices of soil remediation through Fenton oxidation based on studies reported in the specialised literature are then reviewed with a focus on the potential of Fenton-bioremediation and electrokinetic (EK)-Fenton treatments in conjunction with in situ applications. An exhaustive bibliography on column studies is also covered in this work with emphasis on the technical approaches used. Finally, the last section of the article is focused on assisting soil scientists and environmental professionals in implementing in situ Fenton oxidation (ISFO) and provides some insights into future development of ISFO.

This investigation reveals that both methods can remove the color of RB5. Batch experiments were carried out to investigate the process's optimal operational conditions: pH, H2O2 dosage, Fe2+ dosage, RB5 concentration and optimal [Fe2+]0/[H2O2]0/[RB5]0 ratio, to obtain the bests results at low cost, render AOP competitive with other processes. The optimal conditions found were a ratio [H2O2]0/[RB5]0 of 4.9:1, a ratio [H2O2]0/[Fe2+]0 of 9.6:1 and pH = 3.0. The decolorization experiments indicate that RB5 can be effectively decolorized using Fenton and photo-Fenton processes with a little difference between the two processes, 97.5% and 98.1%, respectively, for optimal conditions. This small difference in dye decolorization is not similar to TOC removal: with photo-Fenton process there is a significant increment (46.4% TOC removal) relatively to Fenton process (only 21.6% TOC removal). This fact indicates that although UV low-pressure mercury lamp has little effect on dye decolorization it is particularly important in dye mineralization. AU - Lucas, Marco S. AU - Peres, José A.

Mediterranean countries are mostly affected by this serious environmental problem since they are responsible for 95% of the worldwide oliveoil production. There are many methods used for OMW treatment, such as adsorption, electro coagulation, electro-oxidation, biological degradation, advanced oxidation processes (AOPs), chemical coagulation, flocculation, filtration, lagoons of evaporation and burning systems, etc. Currently, there is no such economical and easy solution. The aim of this study was to evaluate the feasibility of decolourization and removal of phenol, lignin, TOC and TIC in OMW by UV/H2O2 (AOPs). The operating parameters, such as hydrogen peroxide dosage, times, pH, effect of UV and natural sunlight were determined to find the suitable operating conditions for the best removal. Moreover, there is no study reported in the literature related to the use of UV/H2O2 and lime together in OMW treatment. Methods OMW was obtained from an olive-oil producing plant (Muğla area of Turkey) which uses a modern production process. No chemical additives are used during olive oil production. This study was realised by using two different UV sources, while taking the time and energy consumption into consideration. These two sources were mercury lamps and natural sunlight. Before starting AOPs experiments, one litre of OMW was treated by adding lime until a pH of 7.00. Then, 100 ml was taken from each sample, and 1 to 10 ml of a 30% H2O2 (Riedel-deHaen) solution was added. These solutions in closed vessels were laid in the natural sunlight for a week and their compositions and colour changes were analysed daily by UV-Vis spectrophotometer. At the end of the one-week period, they were treated with lime. In this study, the effect of changes in the initial pH, times and H2O2 concentrations on removal was investigated. At the end of all experiments, changes in colour, phenol, lignin, TOC and TIC concentrations were analysed according to standard methods. Results and Discussion In the samples exposed to natural sunlight and having an H2O2/OMW ratio of 3 ml/100 ml, a significant colour removal was achieved approximately 90% of the time at the end of 7 days. When the same samples were treated with lime (pH: up to 7), 99% efficiency was achieved. When phenol and lignin removals were examined in the same concentration, phenol and lignin removal were found 99.5%, 35%, respectively. However, for maximum lignin removal, more use of H2O2 (10 ml H2O2/100 ml OMW) was found to be necessary. Under these conditions, it was found that lignin can be removed by 70%, but to 90% with lime, at the end of a seven-day period. Rate constants obtained in the experiments performed with direct UV were found to be much higher than those of the samples exposed to natural sunlight (ka lignin = 0.3883 ≫ kb lignin = 0.0078; ka phenol = 0.5187 ≫ kb phenol = 0.0146). Moreover, it should be remembered in this process that energy consumption may induce extra financial burden for organisations. Conclusions It was found, in general, that colour, lignin, total organic carbon and phenol were removed more efficiently from OMW by using H2O2 UV and lime OMW. Moreover, in the study, lime was found to contribute, both initially and after radical reactions, to the efficiency to a great extent. Recommendations and Perspectives Another result obtained from the study is that pre-purification carried out with hydrogen peroxide and lime may constitute an important step for further purification processes such as adsorption, membrane processes, etc. AU - Uğurlu, Mehmet AU - Kula, İbrahim DA - 2007/07/01/ DO - 10.1065/espr2006.06.315 DP - link.springer.com J2 - Env Sci Poll Res Int KW - Advanced oxidation processes (AOPs) Atmospheric Protection/Air Quality Control/Air Pollution colour Environment, general Industrial Pollution Prevention lignin lime treatment olive mill wastewater (OMW) phenols total inorganic carbon (TIC) total organic carbon (TOC) Waste Water Technology / Water Pollution Control / Water Management / Aquatic Pollution L1 - files/291/Uğurlu and Kula - 2007 - Decolourization and removal of some organic compou.pdf LA - en M1 - 5 PY - 2007 SN - 0944-1344, 1614-7499 SP - 319-325 ST - Decolourization and removal of some organic compounds from olive mill wastewater by advanced oxidation processes and lime treatment T2 - Environmental Science and Pollution Research - International TI - Decolourization and removal of some organic compounds from olive mill wastewater by advanced oxidation processes and lime treatment UR - http://link.springer.com/article/10.1065/espr2006.06.315 files/292/espr2006.06.html VL - 14 Y2 - 2013/01/15/04:02:29 ID - 326 ER - TY - JOUR AB - Water pollution control is presently one of the major thrust areas of scientific research. While coloured organic compounds generally impart only a minor fraction of the organic load to wastewaters, their colour renders them aesthetically unacceptable. Stringent regulating measures are coaxing industries to treat their waste effluents to increasingly high standards. Colour removal, in particular, has recently become an area of major scientific interest as indicated by the multitude of related research reports. During the past two decades, several decolourization techniques have been reported, few of which have been accepted by some industries. There is a need to find alternative treatments that are effective in removing dyes and colourants from large volume of effluents, which are cost-effective, like the biological or integrated systems. This article reviews some of the widely used and most promising industrial wastewater decolourization methods. Data on decolourizing efficiencies of different causative agents, obtained by means of different physical, chemical and biological methods are discussed. Further a critical review is made on the various treatment methodologies and emerging technologies with a note on their advantages and disadvantages. AU - Anjaneyulu, Y. AU - Chary, N.

Although prohibited in the European Union because of widespread contamination of waterways and drinking water supplies, it is still one of the most widely used herbicides in the world. Atrazine and some of its degradation products are among the most commonly found xenobiotics in groundwater and soils in the world. It is also an endocrine disruptor that causes abnormal reproductive development and immune suppression in wildlife. The purpose of this study was to identify the degradation products of atrazine. Fenton reaction treatment, a hydroxyl radical oxidation process recently developed for the degradation of aqueous pesticide waste, was applied to the degradation of atrazine. Classical and modified Fenton reactions have been used as Advanced Oxidation Process treatment methods. A HPLC method was developed and optimized for the identification of resulting degradation products. In general, very good atrazine degradation efficiencies were achieved by both of the methods used. The degradation products, such as oxalic acid, urea, formic acid, acetic acid, and acetone, were identified by HPLC with a photodiode array detector.

Apart from the effect of metals for chelating agents as a major influencing factor, selected information such as pH, oxidant’s dose, concentrations of pollutants and treatment performance is presented. The performance of individual AOP is compared. It is evident from our literature survey that photocatalysis with UV irradiation alone or coupled with TiO2, ozonation and Fenton’s oxidation are frequently applied to mineralize target pollutants. Overall, the selection of the most suitable AOP depends on the characteristics of effluents, technical applicability, discharge standard, regulatory requirements and environmental impacts.

These waste streams contain numerous toxic dyes, which are resistant to natural breakdown and degradation. Therefore, there is a need to find economical and bio-friendly methods to degrade textile dyes. In this study, degradation of Methyl Red, an azo dye, was studied using the ferrous-hydrogen peroxide system. The oxidation and subsequent degradation of the dye was found to be dependent on both the amount of Fe2+ ions as well as hydrogen peroxide. In order to study the effect of other salts that are normally present in textile waste streams, a systematic study was carried out using 10 different salt solutions. Some of the ions tested enhanced the rate and extent of degradation of the dye, whereas some had an inhibitory effect. The rates of degradation were found to fit to first-order kinetics.

In this work, we have investigated the effectiveness of the Fenton’s reagent (H2O2-Fe2+) to treat monoethanolamine (MEA) as a model compound in simulated wastewater. Degradation studies were carried out in a jacketed glass reactor. The effects of concentrations of ferrous sulfate, hydrogen peroxide, and the pH of a solution on the rate of reaction were determined. A pH of 3 was found to be the optimum. The degradation reaction proceeds very fast at the beginning but slows down significantly at a longer time. A larger fractional degradation of the organics in solution was observed if the initial chemical oxygen demand (COD) of the feed solution was high. Gradual addition of H2O2 to the reaction mixture increased the COD removal by about 60% compared to one-time addition of the reagent at the beginning of the process. A rate equation for mineralization of the amine was developed on the basis of a simplified mechanistic model, and the lumped value of the rate constant for COD removal was determined. A partially degraded MEA solution as well as “pure” MEA was subjected to biological oxidation by activated sludge. The former substrate degraded much faster. The degradation rate and biomass generation data could be fitted by the Monod kinetic equations. AU - Harimurti, Sabtanti AU - Dutta, Binay K. AU - Ariff, Idzham Fauzi B. M.

It was shown that organic matter is efficiently degraded through a Fenton-like reaction using FeCl3 as catalyst in the presence of hydrogen peroxide. Oxidation was carried out in a batch reactor with controlled temperature. Operating at pH 3.0, H2O2 concentration = 100 g dm−3, [FeCl3]/[H2O2] ratio = 0.04, and ambient temperature (281–285 K), 92.6% of chemical oxygen demand and 99.8% of total phenols were removed. Kinetics can be described by a two step first order model. The kinetic parameters at ambient temperature and pH 3 were calculated. In the temperature range 278–313 K, the best performance was obtained at 303 K. The experiments performed at different temperatures allowed to calculate the apparent activation energy Ea = 8.7 kJ mol−1.

The BBD can be used to find the optimal conditions in multivariable systems. The optimal conditions obtained by the design were further applied in the kinetic analysis of o-toluidine oxidation in fluidized-bed Fenton process. Materials and methods The 1.35-L fluidized-bed reactor used in all experiments was a cylindrical vessel with an inlet, outlet, and recirculation pump. The o-toluidine was determined by high-performance liquid chromatography. Results and discussion Analytical results indicated that pH, Fe2+, and H2O2 were significant factors in o-toluidine and chemical oxygen demand (COD) removal, but loading carrier was not. The pH significantly affected not only o-toluidine degradation, but also total iron removal. The predicted conditions for optimal removal of 1 mM of o-toluidine using 100 g of carriers were pH 3 ± 0.5, 1 mM of Fe2+, and 17 mM of H2O2. Removal of o-toluidine and COD in the actual experiment was higher than predicted, whereas removal of total iron was slightly lower. The kinetic study showed that the initial rate and rate constant (k) of o-toluidine degradation in the fluidized-bed Fenton process correlated Fe2+ concentration. In the Fe2+/H2O2 stage, high concentration of H2O2 produced a scavenging effect. Conclusions The predicted removal efficiencies of o-toluidine and COD were 90.2% and 41.4%, respectively. Moreover, the removals of o-toluidine and COD in the actual experiment were 99.8% and 61.8%, respectively.

Metol [N-methyl-p-aminophenol] was chosen as a model. Degradation of this compound by Fenton’s reagent was examined under dark conditions as a function of reagent concentrations and pH used in batch treatments. Under optimal conditions, 0.2 M H2O2, 9.0×10−4 M Fe2+, pH 3–5 and room temperature, the initial COD of a 5×10−3 M metol solution was reduced by about 50% within 2 h. After this time, additional COD reduction was very slow (about 20% in five days). No aromatic compounds were detected about 4 h of reaction indicating that residual organic matter was mainly made up of ring cleavage products. Metol conversion behaved as a first-order reaction with respect to metol and Fe2+. Complete destruction of residual organic matter could be achieved at high temperatures (about 60°C) or by using the photo-Fenton reaction, which thus opens up prospects for an effective treatment of p-aminophenols in effluents from photographic processes.

Several early studies for PG degradation focused on biological process, which usually proceeds at a slow rate and is often inhibited by substances which are toxic to the microorganisms. In this paper, Fenton method was exploited for treating PG wastewater in a semi-continuous reactor with adding ferrous sulfate (FeSO4) and hydrogen peroxide (H2O2) to the reactor, respectively. Semi-continuous applications of H2O2 and Fe2+ could result in low steady state of HO, which would minimize HO scavenging and further increase PG oxidation efficiency. Under the optimal conditions, 99.1% of PG conversion and 88.4% of COD removal were achieved. In addition, pseudo-first-order model, in which the concentration of HO was assumed to remain constant, was established. The intrinsic activation energy of HO with PG, calculated by Arrhenius-equation was 35.18 kJ/mol. The intrinsic reaction rate constant of HO with PG around optimal conditions was 1.56–1.72 × 108 M−1 s−1. After Fenton's reaction, PG molecules could not be thoroughly oxidized to H2O and CO2. Intermediates, such as aldehyde, acetone, methanol, formic acid, and acetic acid, were checked by GC–MS, which all had a very low content and toxicity. As a homogeneous catalytic oxidation, Fenton oxidation is a feasible treatment for PG wastewater for its low toxicity, low price, and high efficiency.

The efficiency of the treatments was evaluated on the basis of SA degradation degree, COD and BOD reduction. Due to the tendency of SA to form complexes with ferric iron, decreasing the concentration of catalyst and increasing that of hydrogen peroxide intensified SA degradation by the classical Fenton process. Application of Fe3+/H2O2 led to the same SA degradation degree as classical Fenton process with the following termination, where the entire residual SA is complexed with Fe3+. SA degradation by modified Fenton was intensified with higher goethite concentration and in acidic pH conditions. The addition of UV-irradiation did not improve the action of the Fenton's/modified Fenton's reagent system. Overall COD and BOD removal efficiency comprised nearly 90% under optimal treatment conditions applied. AU - Goi, A. AU - Veressinina, Y. AU - Trapido, M.

Experiments were conducted in a batch reactor to examine the effects of operating variables like pH, hydrogen peroxide concentration (H2O2) and ferrous ion concentration (Fe2+) on chemical oxygen demand (COD) removal. The progress of the degradation reaction was monitored by the decrease in COD content in the treated solution. The optimal reacting conditions were experimentally determined and it was found to be [H2O2]=31.64 mM, [Fe2+]=0.90 mM for o- and p-cresol while 0.72 mM for m-cresol at pH=3.0±0.2. The degradation efficiency for cresol isomers was as high as 82% within 120 min at optimum conditions. A pseudo-first-order kinetic model was adopted to represent the Fenton oxidation for cresols. The mineralization rate for cresols obeys the following sequence: m->p->o-. Maximum degradation occurred at 30 °C for the temperature range of 20–50 °C studied. The global activation energy for the first-order reaction was estimated to be in the range of 12.90–16.25 kJ/mol. Air/nitrogen did not play an active role in completely mineralizing the organic intermediates at the experimental conditions adopted. Irrespective of the position of methyl group in o-, m- or p-position, the maximum dissolved organic carbon (DOC) removal efficiency was 42%. Only 2/5th of cresol was mineralized to CO2 by Fenton process. The results showed that the cresols were completely oxidized and degraded into lower molecular weight aliphatic acids. Among the acids, acetic and oxalic acids were identified as the major products formed during the degradation. AU - Kavitha, V. AU - Palanivelu, K.

The mineralization efficiencies using ozone alone are 15%, 40% and 15% for the water samples after reverse osmosis (RO), microfiltration (MF) and superfiltration (SF) processes, respectively. The presence of hydrogen peroxide in photochemical reaction matrixes can effectively enhance the mineralization of organic carbon species.

The experimental results indicate that the oxidation process leads to a reduction in the chemical oxygen demand (COD) concentration up to 45%. Moreover, the reduction is reasonably fast at the first stages of the process, since the COD concentration is decreased up to 45% within four hours and further treatment time does not add up to the overall decrease in the COD concentration (48% reduction within six hours). The maximum color removal achieved was 71.5%. In addition, the alterations observed in the organic matter during the development of the process, as indicated by the ratios of COD/TOC and BOD/COD and the oxidation state, show that a great part of the organic substances, which are not completely mineralized, are subjected to structural changes to intermediate organic by-products.

The organic carbon content of the studied OMW was characterized by a COD level of around 40,000 mg/L, with 13,500 mg/L of TOC and 1670 mg/L of total phenols. The corresponding antioxidant activity (AOA) was determined as 33,400 mg/L. PSD of the selected organic carbon parameters was investigated using a sequential filtration/ultrafiltration procedure. COD fractionation based on PSD revealed two major components, a soluble fraction below 2 nm and a particulate fraction above 1600 nm representing 49% and 20% of the total COD, respectively. The remaining COD was distributed in the colloidal and supracolloidal zones. The PSD of TOC, total phenols and AOA exhibited similar profiles with peaks at the two ends of the studied size range. Overall COD removals achieved via Fenton's oxidation both at pH = 3.0 and pH = 4.6 (the original pH of the OMW) remained in the range of 40–50%. As anticipated, the effect of Fenton's treatment was more pronounced in the soluble size range. Fenton's oxidation at pH = 3.0 resulted in 46% and 63% removals for total phenols and AOA, respectively. The results obtained indicated that Fenton's process could only be useful as an alternative preliminary treatment option of the required full treatment scheme that could involve a sequence of filtration, oxidation and/or biological treatment steps.

Factors such as feeding mode and concentration of the hydrogen peroxide were explored. Results showed that the feeding mode of H2O2 did not significantly affect the aniline oxidation in the electro-Fenton process. However, the aniline oxidation slightly decreased with the two-step addition of H2O2 in the fluidized-bed Fenton process. Presumably the decline of remaining Fe2+ led to destitute hydrogen radicals from the Fe2+-catalyzed H2O2. In addition, the removal efficiency of aniline was maintained at a maximum as H2O2 concentration was higher than 0.04 M in the electro-Fenton process. Meanwhile, the almost exhausted H2O2 would increase the amount of Fe2+ in the solution for the electro-Fenton process. This is because the Fe2+ is regenerated through the reduction of Fe3+ on the cathode. The electro-Fenton process has a stronger oxidative ability with regard to the production of the oxalic acid than fluidized-bed Fenton process which was attributed to a higher consumption of H2O2. Therefore, in the aspect of H2O2 depletion, the mineralization efficiency of the fluidized-bed Fenton process was higher than that of the electro-Fenton process.

The experimental results were estimated in terms of chemical oxygen demand (COD) and color reductions to examine the treatment efficiency. The optimum pH was observed to be around 3. The decolorization and the oxidation efficiencies could achieve 92% and 49%, respectively, in only 2 min of reaction under the concentration ratio of [COD]:[Fe2+]:[H2O2] = 1:0.95:3.17. By using this process, the oxidation of textile wastewater increased with increasing H2O2 dosage. The highest level of oxidation was 87%.

Among the treatments proposed for abatement of these compounds Advance Oxidation Processes (AOPs) have been used. Many studies are focused on elimination of the original pollutant and TOC while less attention has been paid for generated oxidation intermediates and their associated toxicity. In this work nicotine was used as target pollutant and Fenton's Reagent (FR) as AOP. Nicotine and TOC conversion were obtained and an estimation of the toxicity of the oxidation intermediates produced was determined by using Microtox. Reactions were carried out in a batch manner, at two different temperatures (20 and 50 °C), using different amounts of hydrogen peroxide (5% to 200% of the stoichiometric dosage required for complete mineralization). Complete nicotine removal was achieved with FR at low oxidant doses even at 20 °C. However, only about 60% TOC percent removal was achieved. Moreover some toxic intermediates were generated, especially at initial oxidation stages. For example, for nicotine conversion 80% and TOC conversion 10%, toxicity obtained was fifteen times higher than the initial one. This must be taken into account in order to elucidate the time required and the effectiveness of the process.

The traditional contaminants examined were trichloroethene (TCE) and 2,4-dichlorophenol (2,4-DCP) while 1,4-dioxane (1,4-D) and 1,2,3-trichloropropane (TCP) were studied for the relatively new contaminants. The mineralization and biodegradability were represented by dissolved organic carbon (DOC) reduction and the ratio of biodegradable dissolved organic carbon and DOC, respectively. For all four contaminants, Fenton reagent using Fe2+ was more effective in the DOC reduction than Fenton reagents using Fe3+ and Fe0 in most cases. The types of Fe that provided maximum biodegradability increase were not the same for all four compounds, Fe3+ for TCE, Fe0 for 2,4-DCP, Fe2+ for 1,4-D, and Fe3+ for TCP. When the combination of DOC elimination and biodegradability increase (least refractory fraction) was considered, Fe2+ was the best choice except for 2,4-DCP which was susceptible to Fe0 catalyzed Fenton reagent the most. The least refractory fractions remaining after 120 min of reaction were 20–25% for TCE, 2,4-DCP, and TCP and 30–40% for 1,4-D. The iron type in Fenton reaction also affected the type of mineralization kinetics of TCE, 2,4-DCP, and TCP as well as the types of degradation by-products of these contaminants. Some of the by-products found, such as isopropanol and propionic aldehyde, which were produced from Fe0 catalyzed Fenton degradation of TCP, have not been previously reported.

The influence of Fe2+ and hydrogen peroxide ratio, hydrogen peroxide dose, pH and treatment time were investigated. The degradation of non-ionic surfactant and other organic compounds was analysed as COD, TOC and molecular weight distribution (MWD). The most cost-effective degradation conditions were at H2O2/Fe2+ stoichiometric molar ratio of 2 with 5 min mixing and H2O2 dose of 1000 mg l−1. With the initial pH of 6, the reductions of COD and TOC were 85% and 69%, respectively. However, the removal of the organic compounds was mainly carried out by Fenton-based Fe3+ coagulation rather than Fenton oxidation. Fenton process proved to be much more efficient than previously performed ozone-based oxidation processes.

The sample used was the biologically treated leachate in the Kimpo metropolitan landfill site in Korea and its COD, BOD5, NH3–N and Cl− concentrations were about 1500, 30, 1300 and 4500 mg/l, respectively. The COD removal by oxidation of the organic substances with hydrogen peroxide was most efficient in the pH range of 2.5–4. However, it drastically decreased according to the pH value above 5. The COD removal efficiency by coagulation increased with the increase of the ferrous sulfate dosage, but the overall efficiency over a minimum dosage of 500 mg/l was scarcely changed. The efficiency of hydrogen peroxide actually used in the oxidation of the organic substances was only about 45%. The optimum range of the coagulation pH to maximize the COD removal efficiency by coagulation was 3–6, but that was slightly lower than the pH range of 6–9 generally known in the literature.

An active bacterial consortium enriched from the MGP surface soil (0–2 m) biodegraded more than 90% of PAHs including 2-, 3-, and 4-ring hydrocarbons in a model soil. The consortium was also able to transform about 50% of 4- and 5-ring hydrocarbons in the MGP soil. As a chemical oxidant, Fenton's reagent (H2O2+Fe2+) was very efficient in the destruction of a mixture of PAHs (i.e., naphthalene (NAP), fluorene (FLU), phenanthrene (PHE), anthracene (ANT), pyrene (PYR), chrysene (CHR), and benzo(a)pyrene (BaP)) in the model soil; noticeably, 84.5% and 96.7% of initial PYR and BaP were degraded, respectively. In the MGP soil, the same treatment destroyed more than 80% of 2- and 3-ring hydrocarbons and 20–40% of 4- and 5-ring compounds. However, the low pH requirement (pH 2–3) for optimum Fenton reaction made the process incompatible with biological treatment and posed potential hazards to the soil ecosystem where the reagent was used. In order to overcome such limitation, a modified Fenton-type reaction was performed at near neutral pH by using ferric ions and chelating agents such as catechol and gallic acid. By the combined treatment of the modified Fenton reaction and biodegradation, more than 98% of 2- or 3-ring hydrocarbons and between 70% and 85% of 4- or 5-ring compounds were degraded in the MGP soil, while maintaining its pH about 6–6.5.

The role of chemical oxidation depends on the treatment objectives and may vary from partial remediation to complete mineralization. In the case of partial treatment, chemical oxidation aims at the selective removal of the more bioresistant fractions and their conversion to readily biodegradable intermediates that can subsequently be treated biologically. Coupling chemical pre-oxidation with biological post-treatment is conceptually beneficial as it can lead to increased overall treatment efficiencies compared with the efficiency of each individual stage. This paper reviews recent developments and highlights some important aspects that need to be addressed when considering such integrated schemes.

The variables considered were the temperature, H2O2 concentration and Fe2+:H2O2 ratio, for a dye concentration of 0.3 mM and pH 3. The multivariate experimental design allowed to develop quadratic models for: (i) color removal and (ii) total organic carbon (TOC) reduction (both after 2 h of reaction), which were adequate to predict responses in all the range of experimental conditions used. Under the optimum conditions, performances of 99.7 and 70.7% for color and TOC removal, respectively, were experimentally reached. It was found that both H2O2 concentration and temperature have an important effect in the organic matter degradation efficiency. AU - Ramirez, J. Herney AU - Costa, Carlos A. AU - Madeira, Luis M.

This study aimed to evaluate the technical, economical and environmental feasibility for applying AOTs at decentralised wastewater treatment. A comprehensive process selection and assessment framework for the application of AOTs in decentralised wastewater systems for wastewater recycling and reuse purposes were developed in this study. Different AOTs were assessed for their suitability to retrofit as an advanced wastewater treatment option to a decentralised wastewater case study plant in South East Queensland, Australia to produce Class A+ recycled water. Among the different AOTs assessed, it was assessed that the H2O2/UV process was the best AOT treatment option, in terms of technical, economic and environmental benefits for treating sewage effluent from the decentralised wastewater system analysed in this case study. It is anticipated that additional data sets from different pilot or full scale AOT plants will allow the performance predictions of AOTs for a wide range of decentralised wastewater treatment applications. Through this study, it is anticipated that the potential future uptake of AOTs as an advanced treatment option will be enhanced, given the comprehensive and detailed technical, economic and environmental analysis presented in the paper.

The independent variables considered for the optimization of the oxidative process were temperature, H2O2 and Fe (II) concentrations. Under the best stand-alone Fenton operating conditions: T = 25 °C, pH = 3; [H2O2] = 1650 mg L− 1 and [Fe (II)] = 216 mg L− 1, we achieved 64% TOC reduction and > 99% E. coli removal. However, the best results were obtained when applying Fenton process with [H2O2] = 1518 mg L− 1 and [Fe (II)] = 66.5 mg L− 1, as a biological polishing step. The aerobic biological treatment was conducted using a SBR with 1 day HRT. In this case 92% TOC and > 99% E. coli removal were accomplished. The obtained results showed the feasibility of both processes to achieve suitable water qualities for internal reuse, according to RD 1620/2007.

The experimental conditions tested during this study provide the simultaneous occurrence of Fenton, Fenton-like and photo-Fenton reactions. The batch experimental results are assessed in terms of total organic carbon reduction. Identification of some of the chemical constituents of the effluent was performed by means of GC–MS. Other pollution related features of the initial effluent-like COD and color were also measured. The main parameters that govern the complex reactive system, i.e., light intensity, temperature, pH, Fe(II) and H2O2 initial concentrations have been studied. Concentrations of Fe(II) between 0 and 400 ppm, and H2O2 between 0 and 10,000 ppm were used. Temperatures above 25°C and up to 70°C show a beneficial effect on organic load reduction. A set of experiments was conducted under different light sources with the aim to ensure the efficiency of using solar light irradiation. The combination of Fenton, Fenton-like and photon-Fenton reactions has been proved to be highly effective for the treatment of such a type of wastewaters, and several advantages for the technique application arise from the study.

Aiming both the selection of the best operating conditions (pH, Fe2+:H2O2 ratio and initial H2O2 concentration) and the evaluation of the overall reaction kinetics, trials were performed in a batch reactor. Operating at pH=3.2, H2O2 concentration=10.6 g/L and Fe2+:H2O2 ratio=1:5 (by weight), about 66.4% of total organic carbon (TOC), 87.3% of chemical oxygen demand (COD) and 70.2% of biochemical oxygen demand (BOD5) were removed and an increase of the BOD5/COD ratio from 0.27 to 0.63 was achieved. In the temperature range 20–50°C, the best performance was obtained at 30°C. The kinetic study was undertaken at different initial TOC concentrations and temperatures. Overall kinetics can be described by a second-order followed by a zero-order rate equation and the apparent kinetic constants at 30°C are k=2.3×10−4 L/mg min and k0=26.0 mg/L min, respectively. The experiments performed at different temperatures confirmed the global kinetic model and allowed to calculate the global activation energy for the second-order reaction (70.7 kJ/mol).

It was necessary to continuously measure the fluctuating concentration of organics in the pigment wastewater and to determine the amount of Fenton’s reagent required to oxidize the organics. Batch and continuous flow tests were used to evaluate the relationship between the concentration of organics (CODCr) and the amount of Fenton’s reagent required to achieve a sufficient oxidation of the organics. On-line measurements of the oxidation-reduction potential (ORP) value in the batch and continuous flow tests showed that the maximum ORP values were highly related to the organic concentrations (expressed as CODCr) and the Fenton’s reagent dosage (expressed as H2O2 concentration). The empirical equation was [CODCr]=8808+0.494[H2O2]-14.6ORP. A control program of Fenton’s reagent dosage based on the empirical equation was applied to control of a pilot scale Fenton oxidation process using ORP measurement. The concentration of organics predicted with the control program well agreed with the observed concentration of organics in the pigment wastewater. The variation of the effluent organics concentration of the controlled Fenton oxidation process was significantly reduced compared to that of a process without the control system. These results suggested that the control system of Fenton’s reagent dosage using ORP measurement would be applicable to the Fenton oxidation process for efficient pretreatment of pigment wastewater.

The simulated wastewater contained less than 0.2% polyvinyl alcohol (PVA) and Blue G (a direct dye) or Black B (a reactive dye). Experiments were conducted to investigate the effects of operating variables, including pH, temperature and the treatment time, on the COD removal efficiency. Optimal operating conditions were experimentally determined. Chemical coagulation using polyaluminum chloride and polymer was found to complement the Fenton treatment process in reducing the floc settling time, enhancing color removal and reducing Fe ion concentration. A two-step Fenton treatment process intended separately for chemical coagulation and chemical oxidation was observed to be only marginally better than the single-step one. A kinetic model for the Fenton treatment process was also proposed and the kinetic rate coefficients determined based on the experimental data. AU - Lin, Sheng H. AU - Lo, Cho C.

In this work, we performed extensive experimental study of chemical Fenton oxidation in order to understand the optimal operative conditions to be applied in real industrial wastewaters treatment. We analyzed the effectiveness of chemical oxygen demand (COD) removal from different wastewaters within a wide range of initial COD content. We observed a maximum COD % removal of about 80%, assessing the efficiency of the process. In order to understand the role of different reagents in the final yield, we performed a factorial experimental approach on the Fenton's reagents (H2O2 and Fe2+) and analyzed the results developing an analytical second-order model. The model depends on three variables, namely: the initial [CODi] of the sample, the [CODi]/[H2O2] ratio and [H2O2]/[Fe2+] ratio. We obtained an accurate description of the COD % removal in different initial conditions, with a R2 = 0.85. In particular, we observed that optimal quantities of Fenton's reagents are a function of the initial COD of the treated wastes.

Experiments were conducted at the optimal operating parameters for each Fenton type process and studied coloured pollutants established in Part I of this study in order to find the optimal dose of applied zeolites and understand their role in the new combined AOPs. Degradation of the studied dyes, C.I. Reactive Blue 49 and C.I. Reactive Blue 137, was monitored by means of the UV/VIS, TOC and AOX analysis, thus determining decolourization and mineralization extents of model solutions. Organic content adsorbed onto applied zeolites after the treatment was scanned and characterized using FT-IR spectrophotometer. Applied AOPs in combination with zeolites were shown to be very successful in colour removal, >98%, similarly like Fenton type processes reported in Part I of this study, while improvements in the mineralization of the studied dyes depended on the type and the dose of zeolite, as well as on dye structure and the type of applied AOP.

A class of chemicals synthesized for tanning or retanning purposes in the leather tanning industry is collectively termed synthetic tannins (syntans, ST), resins (acrylic), oils (OLs), etc. The literature on tannins is focused on individual chemical species, e.g. tannic or gallic acid, thus providing only scanty information on tannin complex mixtures and their fate in the biological treatment/aquatic environment. The present study evaluates Fenton’s oxidation (FO) as the most basic advanced oxidation process for treatment of four types of STs [(ST1: cresol-based, ST2: poly-condensed formaldehyde and disulphane with sulfonic aromatic acids, ST3: phenol-based, ST4:condensed phenol-based). FO conditions were also tested on oils (OL1: sulphonated, OL2: sulfunated and OL3:phosphorous-based)] individually. These products generate the highest COD in a re-tanning process. FO process was performed at pH 3.0 and 40–45°C, which is original temperature of re-tanning process, in the synthetic solutions containing 300 mg/l of COD equivalent of each compound. Among various ratios of H2O2/FeSO4 applied, the highest COD and UV absorbance removal were obtained at 600/500 (mg/mg) ratio for all STs tested. At the same ratio, FO process was also performed versus time for each ST. At the end of 5 min of oxidation, more than 75% COD removal was obtained (75% for ST3, 85% for ST1 and ST2, 90% for ST4) and there was no significant increase in COD removal after 10 min of oxidation except ST1 (which increased up to 15 min) in accordance with UV and oxidation redox potential (ORP) measurements. A ratio of 600/750 mg/mg of H2O2/FeSO4 was the optimum for FO process for the three types of oils. The results obtained in this study indicated the rapid oxidation of re-tanning agents which are hardly biodegradable in biological process.

The possibilities of the reagent arise from the oxidant power of intermediate species generated during the slow oxidation of Fe2+ by H2O2, but very few analytical applications of the reagent can be found. The oxidation of organic compounds (known as the Fenton reaction) is in fact an induced chain reaction that proceeds to an extension which is influenced by the reaction conditions. Experimental design has been used for optimization thinking of the analytical application. The pesticide atrazine has been used as analyte to test the analytical possibilities of the FR. Partial least squares regression (PLS), applied to reaction profiles between 206 and 270 nm, was used as algorithm to make the calibration model. Atrazine concentrations ranging from 0.46 to 13.4×10−5 M have been used for calibration, and mean errors under 2.5% both for calibration and validation have been found. Other classical methods of calibration such as those using absolute values of absorbance, initial rates, etc. gave poor results in the cases considered. According to the study of interferences, the main drawback of the reagent is the lack of selectivity, but some possible ways of improving it are discussed. The method was applied for the determination of atrazine in several commercial atrazine-based pesticide preparations. In general, good results were obtained when compared with those found by gas–liquid chromatography as a reference. Recovery studies also gave satisfactory results. AU - López-Cueto, G. AU - Ostra, M.

Both the H2O2 and Fe(II) initial concentrations increase the PA degradation rate. Temperature also enhances the PA conversion when raised from 283 to 313 K, a further increase to 323 K results in a lower PA removal. Increasing the PA initial concentration leads to a decrease of conversion values but an opposite effect in terms of removal rate. pH values in the range 3?4 resulted in the total inhibition of the oxidation process. Similar PA depletion rates were experienced regardless of the oxidation state of the catalyst (ferrous or ferric iron). Additionally, an attempt based on the classic Fenton's chemistry plus some other stages accounting for the Fe(II) regeneration from Fe(III) and the inefficient H2O2 decomposition was conducted to model the process.

Input operating variables including the concentration of pollutants, iron and hydrogen peroxide as well as the reaction time were used to assess the mineralization degree through a factorial experimental methodology. A TOC removal in the range of 15.0–58.8% was attained within the operational conditions used. A reduced model was achieved using the statistically important independent factors and interactions to predict TOC degradation. On the hydrogen peroxide injection methodology, the results showed that the continuous introduction of small volumes is advantageous when compared with one single addition of the overall volume at the zero reaction time with a mineralization improvement of 11%. The use of FeSO4·7H2O correspondent to a Fe2+ load of 271 mg; [H2O2] = 488.0 mM, injected in twelve aliquots each 30 min during 6 h of reaction reached optimal efficiencies with the parent compounds (quantified by HPLC and the Folin–Ciocalteau method) quickly totally removed and TOC, COD and BOD5 final values of 123 mgC/L, 180 mgO2/L and 146 mgO2/L, respectively. Toxicity assessment by Vibrio fischeri light inhibition revealed that Fenton's process reduces the effluent ecological impact related with the decomposition of the toxic phenolic acids. Indeed, EC50 changed from 32.2% dilution to no-dilution needed. The analysis of BOD5/COD ratio pointed out a high improvement of the treated wastewater biodegradability from 0.30 to 0.80 meaning that the application of Fenton's oxidation as a pre-treatment enables a further application of an efficient post-biological technology which was also confirmed by respirometry.

Efficiencies of both procedures were monitored by chemical analyses and by acute toxicity studies with Vibrio fischeri and measurement of inhibition of oxygen consumption by activated sludge. Leachate was very toxic to V. fischeri and activated sludge and toxicity was not significantly reduced as well as effluent limits were not met during treatment in existing biological treatment plant. Fenton's oxidation, accomplished at different molar ratios of reagents (M(Fe2+)/M(H2O2) was 1/1; 1/3.3; 1/6.6 and 1/13.3) and various temperatures (20–45 °C), assured good removal of organic compounds (80% as COD) as well as other pollutants and slightly reduced toxicity, but effluent limits were not always met. Furthermore, additional oxidation experiments with biologically treated leachate confirmed, that Fenton's oxidation is not appropriate for polishing already treated leachate in SBR, because it degraded persistent organics into more biodegradable, still toxic ones, which could affect oxygen regime in a receiving stream. Fenton's process could not replace SBR treatment plant, but it could be a viable option for pretreatment of landfill leachate. AU - Žgajnar Gotvajn, A. AU - Zagorc-Končan, J. AU - Cotman, M.

The FO unit was considered as the key process for implementation of the proposed modeling scheme. Four input components such as H2O2/chemical oxygen demand ratio, H2O2/Fe2+ ratio, reaction pH, and reaction time were fuzzified in a Mamdani-type fuzzy inference system to predict the removal efficiencies of chemical oxygen demand, total organic carbon, color, and ammonia nitrogen. A total of 200 rules in the IF–THEN format were established within the framework of a graphical user interface for each fuzzy-logic model. The product (prod) and the center of gravity (centroid) methods were performed as the inference operator and defuzzification methods, respectively, for the proposed prognostic models. Fuzzy-logic predicted results were compared to the outputs of multiple regression models by means of various descriptive statistical indicators, and the proposed methodology was tested against the experimental data. The testing results clearly revealed that the proposed prognostic models showed a superior predictive performance with very high determination coefficients (R 2) between 0.930 and 0.991. This study indicated a simple means of modeling and potential of a knowledge-based approach for capturing complicated inter-relationships in a highly non-linear problem. Clearly, it was shown that the proposed prognostic models provided a well-suited and cost-effective method to predict removal efficiencies of wastewater parameters prior to discharge to receiving streams.

The obtained hydrogels were investigated as the adsorbents to remove Cu(II) and Ni(II) from the aqueous solution. The effects of operating parameters on the adsorption capacity were studied, including the composition ratio (AT:AA), contact time, pH and initial concentrations of heavy metal ions. The results indicate that the introduction of allylthiourea into the hydrogel can reduce greatly the swelling ratio, but with no significant variation in the adsorption capacity as the initial Cu(II) and Ni(II) concentrations lower than 400 and 200 mg/L, respectively. In addition, the adsorption capacity shows a pH-independence at pH ⩾ 4.0, and the adsorbed Cu(II) and Ni(II) can be partially desorbed using 0.01 mol/L HCl as the desorbent, rendering the as-prepared hydrogel good re-adsorption ability, especially for Cu(II). The applicability in real electroplating wastewater demonstrates that the as-prepared hydrogel with AT is promising for the removal of Cu(II) and Ni(II) for its comparable adsorption capacity with the hydrogel without AT.

The presence of recalcitrant organics is the major issue in meeting the pollution control board norms in India. The theme of the present investigation was on partial or complete removal of pollutants or their transformation into less toxic and more biodegradable products by heterogeneous Fenton oxidation process using mesoporous activated carbon (MAC) as the catalyst. Materials and methods Ferrous sulfate (FeSO4·7H2O), sulfuric acid (36 N, specific gravity 1.81, 98% purity), hydrogen peroxide (50% v/v) and all other chemicals used in this study were of analytical grade (Merck). Two reactors, each of height 50 cm and diameter 6 cm, were fabricated with PVC while one reactor was packed with MAC of mass 150 g and other without MAC served as control. Results and discussion The oxidation process was presented with kinetic and thermodynamic constants for the removal of COD, BOD, and TOC from the wastewater. The activation energy (Ea) for homogeneous and heterogeneous Fenton oxidation processes were 44.79 and 25.89 kJ/mol, respectively. The thermodynamic parameters ΔG, ΔH, and ΔS were calculated for the oxidation processes using Van’t Hoff equation. Furthermore, the degradation of organics was confirmed through FTIR and UV–visible spectroscopy, and cyclic voltammetry. Conclusions The heterocatalytic Fenton oxidation process efficiently increased the biodegradability index (BOD/COD) of the tannery effluent. The optimized conditions for the heterocatalytic Fenton oxidation of organics in tannery effluent were pH 3.5, reaction time–4 h, and H2O2/FeSO4·7H2O in the molar ratio of 2:1. AU - Karthikeyan, S.

The results showed that original pH, hydrogen peroxide concentration and ferrous sulfate concentration affected ORP value and pretreatment efficacy greatly. Under experimental conditions, the optimal original pH was 6.61, and the optimal hydrogen peroxide and ferrous sulfate concentrations were 1.50 and 0.75 g L−1, respectively. The relationship among ORP, original pH, hydrogen peroxide concentration, ferrous sulfate concentration, and color (COD or BOD5/COD) was established, which would be instructive in on-line monitoring and control of Fenton process using ORP. In addition, the effects of wastewater temperature and oxidation time on pretreatment efficacy were also investigated. With an increase of temperature, color and COD removal efficiencies and BOD5/COD ratio increased, and they were in proportion to the exponent of temperature reciprocal. Similarly, color and COD removal efficiencies increased with increasing oxidation time, and both color and COD removal obeyed the first-order kinetics. The BOD5/COD ratio could be expressed by a second-degree polynomial with respect to oxidation time, and the best biodegradability of wastewater was present at the oxidation time of 6.10 h.

Up to 95% COD removal efficiency was attained using 5.5 g/l FeSO4 and 385 g/l H2O2 at a pH of 3, temperature of 50 °C. The H2O2/Fe2+ ratio (g/g) was found to be between 95 and 290 for maximum COD removal. It was noteworthy that, keeping H2O2/Fe2+ ratio constant within the range of 95–290, it became possible to decrease FeSO4 concentration to 1.1 g/l and H2O2 concentration to 96.3 g/l, still achieving nearly the same COD removal efficiency. The relative efficiencies of Fenton's oxidation and coagulation stages revealed that Fenton's coagulation removed organic compounds which were not removed by Fenton's oxidation, indicating that the Fenton's coagulation acted as a polishing step.

The raw poultry manure wastewater, having a pH of 7.30 (±0.2) and a total COD of 12,100 (±910) mg/L was first treated in a 15.7 L of pilot-scale up-flow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated for 72 days at mesophilic conditions (32 ± 2 °C) in a temperature-controlled environment with three different hydraulic retention times (HRT) of 15.7, 12 and 8.0 days, and with organic loading rates (OLR) between 0.650 and 1.783 kg COD/(m3 day). Under 8.0 days of HRT, the UASB process showed a remarkable performance on total COD removal with a treatment efficiency of 90.7% at the day of 63. The anaerobically treated poultry manure wastewater was further treated by Fenton's oxidation process using Fe2+ and H2O2 solutions. Batch tests were conducted on the UASB effluent samples to determine the optimum operating conditions including initial pH, effects of H2O2 and Fe2+ dosages, and the ratio of H2O2/Fe2+. Preliminary tests conducted with the dosages of 100 mg Fe2+/L and 200 mg H2O2/L showed that optimal initial pH was 3.0 for both COD and color removal from the UASB effluent. On the basis of preliminary test results, effects of increasing dosages of Fe2+ and H2O2 were investigated. Under the condition of 400 mg Fe2+/L and 200 mg H2O2/L, removal efficiencies of residual COD and color were 88.7% and 80.9%, respectively. Under the subsequent condition of 100 mg Fe2+/L and 1200 mg H2O2/L, 95% of residual COD and 95.7% of residual color were removed from the UASB effluent. Results of this experimental study obviously indicated that nearly 99.3% of COD of raw poultry manure wastewater could be effectively removed by a UASB process followed by Fenton's oxidation technology used as a post-treatment unit.

The effect of various operating parameters such as inlet pressure, temperature, and the presence of copper windings on the extent of mineralization as measured by total organic carbon (TOC) content have been studied with the aim of maximizing the extent of degradation. It has been observed that increased pressures, higher operating temperature and the absence of copper windings are more favourable for a rapid TOC mineralization. A new approach of latent remediation has also been investigated where hydrodynamic cavitation is only used as a pre-treatment with an aim of reducing the overall cost of pollutant degradation. It has been observed that approach of latent remediation works quite well with about 50–60% removal of TOC using only minimal initial treatment by hydrodynamic cavitation. AU - Chakinala, Anand G.

The Fe2 + or Fe3 + as catalyst and H2O2 as oxidizing agent are commonly used for the classical Fenton's reaction. In present study, the effect of operating conditions such as pH, reaction time, molar ratio, agitation rate, feeding mode and Fenton reagent concentrations which are important parameters that affect the removal efficiencies of Fenton method were investigated. Under the most favorable conditions, the highest removals of 58.1 and 78.3% were observed for COD and color, respectively. In general, the best operating conditions were pH = 3, Fe = 560 mg L?1, H2O2 = 1020 mg L?1, H2O2/Fe2 + molar ratio = 3, agitation rate = 400 rpm and reaction time = 120 minutes. The results highlighted that stepwise addition of Fenton's reagent was more effective than adding the entire volume in a single step. Excessive hydrogen peroxide and iron have shown scavenging effects on hydroxyl radicals and reduced degradation of refractory organics in the landfill leachate.

This method, based on the use of benzoic acid as probe compound, was applied for evaluating the effect of the operating conditions on the radicals amount produced, their production efficiency (i.e. moles of radicals generated per mole H2O2) and their concentration. A Rotatable Central Composite design (RCC) was used to select the operating conditions in order to get a statistically meaningful data set. Hydrogen peroxide and ferrous ion concentrations ranged between 0.2–1 mM and 0.2–0.5 mM, respectively; humic acid concentration between 0 and 15 mg/L, whereas the soil/water weight ratio in slurry-phase systems between 1:10 and 9:10. The probe compound concentration was 9 or 0.1 mM in experiments aimed to evaluate the total amount or concentration of oxidative radicals, respectively. The obtained results indicated that the amount of radicals generated in both aqueous and soil slurry Fenton's system increased with higher H2O2 concentration and, more specifically, that their production efficiency increased with increasing Fe(II):H2O2 molar ratio. Addition of dissolved organic compounds as humic acid did not notably affect the oxidative radicals amount and concentration. On the contrary, a one order of magnitude reduction in both radicals amount generated and concentration was observed when soil was added to the reaction environment.

The diluted wastewater (1:1) was pre-treated using Fenton's reaction. Optimum operating conditions namely, pH, H2O2 dose, Fe+2, COD:H2O2 ratio and Fe+2:H2O2 ratio were determined. The UASB reactor was fed continuously with the pre-treated wastewater. The hydraulic retention time was kept constant at 48 h (24 h for each stage). The conventional parameters such as COD, BOD, TOC, TKN, TP, TSS, oil and grease, and total phenols were determined. The concentrations of polyphenolic compounds in raw wastewater and effluents of each treatment step were measured using HPLC. The results indicated a good quality final effluent.

Also, binary mixtures of atrazine–alachlor and atrazine–bentazone in pesticide preparations have been resolved. The work shows the way in which interferences and the matrix effect can be modelled. Experimental design has been used to optimize experimental conditions, including the effect of solvent (methanol) used for extraction of atrazine from the sample. The determination of pesticides in commercial preparations was accomplished without any pre-treatment of sample apart from evaporation of solvent; the calibration model was developed for concentration ranges between 0.46 and 11.6 × 10−5 mol L−1 with mean relative errors under 4%. Solid-phase extraction is used for pre-concentration of atrazine in water samples through C18 disks, and the concentration range for determination was established between 4 and 115 μg L−1approximately. Satisfactory results for recuperation of atrazine were always obtained.

Although there is considerable research on the biodegradation of chlorinated compounds combined with the Fenton reaction, the kinetics of degradation and dechlorination of the reaction, with various concentrations of hydrogen peroxide and Fe3+, have been rarely investigated. Therefore, we investigated the degradation and dechlorination of PCE with various concentrations of hydrogen peroxide and Fe3+. The initial concentration of PCE (10 μM) decreased from a value of 8.9 μM (with 0.1 mM of hydrogen peroxide and 5 mM of Fe3+) to 1.1 μM (with 10 mM of hydrogen peroxide and 5 mM of Fe3+); the respective values for chloride ions produced were 0.9 and 21.6 μM. Also, the initial 10 μM of PCE decreased from 8.9 (with 0.1 mM of Fe3+ and 5 mM of hydrogen peroxide) to 2.2 μM (with 10mM of Fe3+ and 5 mM of hydrogen peroxide); the respective chloride ions produced were 0.7 and 14.5 μM. The logarithmic correlations between the degradation and dechlorination coefficients were 0.7682 and 0.7834 for concentrations of hydrogen peroxide and Fe3+, respectively. Both coefficients were used, from all possible cases, to derive six models which displayed both the ratio of degradation and dechlorination and the hydrogen peroxide and Fe3+ concentrations. The dechlorination of PCE could then be predicted with the model obtained by the coefficient with the concentration of hydrogen peroxide and Fe3+. The models could be applied to various Fenton reactions for optimization of degradation or dechlorination, such as biodegradation of PCE which is scarcely degraded by aerobic bacteria.

Guaiacol is considered as a model compound of pulp and paper mill effluent. The experiments were carried out in a laboratory-scale reactor subjected or not to solar radiation. Hydrogen peroxide solution was continuously introduced into the reactor at a constant flow rate. The kinetics of organic matter decay was evaluated by means of the chemical oxygen demand (COD) and the absorbance measurements. The experimental results showed that the Fenton and solar photo-Fenton systems lead successfully to 90% elimination of COD and absorbance at 604 nm from a guaiacol solution under particular experimental conditions. The COD removal always obeyed a pseudo-first-order kinetics. The effect of pH, temperature, H2O2 dosing rate, initial concentration of Fe2+, and initial COD was investigated using the Fenton process. The solar photo-Fenton system needed less time and consequently less quantity of H2O2. Under the optimum experimental conditions, the solar photo-Fenton process needs a dose of H2O2 40% lower than that used in the Fenton process to remove 90% of COD.

Atrazine was used as a model compound. Under the conditions employed in this study ([Atrazine]o<1 μM), the OH radical was the unique species responsible for the oxidation of atrazine. Propagation and termination reactions involving organic radicals were assumed to be of little importance and were not incorporated in the model. The data showed that the effects of pH (pH range: 1–3) and of the concentrations of reactants ([H2O2]o and [Fe(III)]o) on the rates of oxidation of atrazine and of decomposition of hydrogen peroxide were in good agreement with model predictions. The concentration-time profiles for transient species (Fe(II), HO2/O−2 and OH radicals) obtained by computer calculations were also useful to explain the lag period and the pseudo-first order decay which were observed on the experimental kinetic curves of degradation of atrazine AU - Gallard, H.

The application of substoichiometric dosage of H2O2 led to the formation of intermediate compounds, continuing later the oxidation to complete oxidation. An important objective was to analyze the effect of hydrogen peroxide dosage applied and the reaction pH together with the iron oxidation state on the degradation level. A kinetic model was derived from a reaction mechanism postulated which was used to analyze the results of the experiments. Another aim was to analyze the hydrogen peroxide consumption. Noteworthy results include an increase in oxidant consumption to intensify phenol removal. Furthermore, oxidant consumption was analyzed through the ratio H2O2 to phenol removed and the average specific rate of removal (ASRR). By analyzing these two parameters it has been possible to ascertain the most favorable strategy for an efficient application of H2O2.

Reactive Blue 19) and/or other anthraquinone dyes by catalytic effects of iron salt known as Fenton's reagent. As an advanced oxidation method, Fenton's reagent has an advantage that it combines both oxidation and coagulation processes. The influence of the main operating parameters such as iron sulfate and hydrogen peroxide doses, solution pH, temperature, initial dye concentration and presence of different concentrations of sodium chloride and sodium sulfate has been studied systematically at a laboratory scale. The obtained results showed that the best pH value for decolorization of dye solution is 3. An increase in temperature resulted in higher removal rates. Results showed that chloride and sulfate ions have a negative impact on the decolorization of RB19 by Fenton oxidation. The increase of Fe2+ and H2O2 doses accelerated the color and COD removals until a point where further addition of Fe2+ or H2O2 became inefficient and unnecessary. A new empirical kinetic model for investigation of decolorization based on simultaneous first and second-order kinetics was derived and compared to individual first- and second-order kinetic models. The results of the mixed-order kinetics showed excellent correlation with experimental data. AU - Emami, F. AU - Tehrani-Bagha, A. R. AU - Gharanjig, K. AU - Menger, F. M.

Batch experiments were carried out to investigate the role of pH, hydrogen peroxide and Fe2+ levels, PNA concentration and the temperature. The kinetic rate constants, kap, for PNA degradation at different reaction conditions were determined. The test results show that the decomposition of PNA proceeded rapidly only at pH value of 3.0. Increasing the dosage of H2O2 and Fe2+ enhanced the kap of PNA degradation. However, higher levels of H2O2 also inhibited the reaction kinetics. The kap of PNA degradation decreased with the increase of initial PNA concentration, but increased with the increase of temperature. Based on the rate constants obtained at different temperatures, the empirical Arrhenius expression of PNA degradation was derived. The derived activation energy for PNA degradation by Fenton oxidation is 53.96 kJ mol−1.

The observed kinetic reaction coefficient was determined and correlated as a function of hydrogen peroxide concentration and UV intensity. The validity of the rate expression was tested experimentally in a parameterization study. The decolorization rate follows pseudo-first order kinetics with respect to dye concentration. The rate increases linearly with UV intensity and nonlinearly with increasing hydrogen peroxide concentration, going from a linear relationship at low H2O2 concentrations to a maximum as hydrogen peroxide concentration continues to increase. The decolorization rate expression derived from the proposed reaction mechanism was reconciled with that used for correlating the experimental data. AU - Mohey El-Dein, A. AU - Libra, J. A.

Both methods were applied to the treatment of synthetic phenol solutions (100 mg L−1) and of an industrial effluent containing a mixture of ionic and non-ionic surfactants at high load (20 g L−1 of COD). The effects of initial pH, initial H2O2 concentration, Fenton catalyst amount and irradiation time were assessed. According to the oxidation of phenol, it has been found that the oxidation by Fenton's reagent is dependent on the pH, contrary to the microwave system, which is not influenced by this parameter. For both systems, a limiting amount of oxidant has been found; above this point the oxidation of phenol is not improved by a further addition of peroxide. The oxidation of the industrial surfactant effluent has only been successful with the Fenton's reagent. In this case, large amounts of ferrous ions are necessary for the precipitation of the ionic surfactants of the effluent, followed by the oxidation of the non-ionic constituents of the solution.

The model has been validated by fitting phenol oxidation data by using FR in a batch way but could be applied to other wastewaters. The proposed model can be applied to the whole range of hydrogen peroxide dosage, values lower than those theoretically required for total mineralization or excess. To do this the model takes into account the change in the hydrogen peroxide concentration. Moreover, the model is able to explain and predict the asymptotic value obtained for mineralization of the initial TOC due to the complexation of the catalyst (iron cation) with chelating oxidation intermediates. Finally, the model can optimize the dosage of hydrogen peroxide in order to avoid the loss of this reagent. AU - Santos, A. AU - Yustos, P. AU - Rodríguez, S. AU - Romero, A.

Up to 98% ATZ removal can be achieved in the process if the doses of FeII and H2O2 are selected appropriately. Oxidation capacity of the process was successfully predicted through a kinetic approach with three simple and measurable parameters (i.e., two rate constants and a break point time), which makes the model useful in predicting, controlling and optimizing the degradation of ATZ. In addition, the transformation pathways of ATZ decay was successfully investigated by using a novel technology, liquid chromatography electrospray tandem mass spectrometry (LC/ESI-MS/MS). Ten intermediates were identified in the process. The alkylic-oxidation followed by dealkylation and/or dechlorination–hydroxylation were found to be the major pathways of the decay of ATZ in Fenton's process.

The dealkylated species may be further dechlorinated but generally at a lower fraction (<10%) due to the depletion of oxidants. AU - Chan, K. H. AU - Chu, W.

To facilitate practical application of AFT, carbaryl degradation in a continuously stirred tank reactor (CSTR) by AFT was investigated under different experimental conditions, such as carbaryl inlet concentration, Fenton reagent concentration/ratio, and carbaryl feeding flow rate. A higher Fe2+ delivery rate and H2O2 to Fe2+ ratio (H2O2:Fe2+) were found to favor the carbaryl degradation process, whereas flow rate was shown to be a much less significant factor to influence the degradation rate under the evaluated experimental conditions. A kinetic-based semiempirical model was developed to simulate the experimental data, and a very good fit between the model and the raw data was found (R2 > 0.99). A dimensionless parameter (k/q2) was found to be a good indicator of the degradation rate; that is, the higher the k/q2value is, the faster the degradation process is. The rate parameter (k) can be used to evaluate the degradation rate when the flow rate is invariant for a given pesticide. The shape parameter (?) is most likely related to the availability and reactivity of Fenton reagents and hydroxyl radicals. To compare the degradation rate of different pesticides, more information other than k/q2, k, and ? values, such as the instantaneous degradation rate vs time relationship, needs to be considered.

The experiments demonstrated that HA was removed by oxidation and coagulation. Moreover, the oxidation occurred mainly at the first 60 min and predominated the HA removal efficiency. A new kinetic model was established according to the generally accepted mechanism of high active OH oxidation in order to well describe the Fenton oxidation reaction in HA aqueous solution. The model embraced two key operating factors affecting the HA degradation in Fenton process, including the dosages of hydrogen peroxide and ferrous ion. The experimental data were fitted by using the most commonly used first- and the second- order reaction models and the new model, respectively. The goodness of fittings demonstrated that the new model could better fit the experimental data than the other two models, which indicated that this analytical model could better describe the kinetics of Fenton reaction mathematically and chemically. Results indicated that the oxidation rate and removal efficiency were strongly dependent on initial pH, initial concentration of Fenton reagents, initial HA concentration and reaction temperature. The experiments demonstrated that hydrogen peroxide and ferrous ion would approach their saturated value with increasing dosage.

The degradation of ATZ was effectively achieved by hydroxyl radicals, which were generated in the FR process. The decay rates of ATZ and the oxidation capacities of FR were found to depend on the concentrations of hydrogen peroxide and ferrous ion. The removal kinetics of ATZ are initiated by a rapid decay and then followed by a much slower one. After an extended reaction time (5–10 min), the reactions ceased because the Fe(II) and H2O2 were consumed and would be deactivated in the process. A mathematical model was successfully developed to describe the two-stage reaction kinetics by using two simple but critical parameters: the initial ATZ decay rate and the final oxidation capacity of Fenton’s process. In general, higher [Fe(II)] or H2O2 concentrations result in faster initial decay rate and higher oxidation capacity. However, the oxidation capacity is more sensitive to the initial [Fe(II)] due to the presence of side reactions as discussed in the paper. AU - Chan, K. H. AU - Chu, W.

The effects of pH, temperature, Cl− concentration and initial concentrations of O-II, hydrogen peroxide (H2O2) and ferrous ion catalyst (Fe2+) on the degradation rate have been investigated in a batch reactor. The apparent kinetic constants, kap, for O-II degradation were determined in the following ranges of experimental conditions: 2.0 ≤ pH ≤ 4.0, 283 K ≤ T ≤ 323 K, 0   M ≤ C C l − ≤ 1 × 10 − 2   M , 3 × 10 − 5   M ≤ C OI I o ≤ 1 × 10 − 4   M , 1 × 10 − 4   M ≤ C H 2 O 2   o ≤ 1 × 10 − 3   M and 2.5 × 10 − 6   M ≤ C F e o 2 + ≤ 2 × 10 − 5   M . A pseudo first-order reaction rate with respect to O-II concentration was found to be adequate to fit the data in these experiments, in which kap depends on the initial conditions following a power-law dependency (at optimum pH of 3 and absence of chloride ions). This equation, without further fitting parameters, was successfully used to validate experiments performed in a continuous stirred tank reactor (CSTR). The ability of the model predictions was also checked by performing experiments in the CSTR out of the above-mentioned ranges (used for the kinetic study). AU - Ramirez, J.

In this study, a coagulation process combined with Fenton oxidation was evaluated for the removal of refractory organics in leachate. Recycling of sludge generated from Fenton oxidation to a coagulation process was attempted to reduce operation cost and to improve organic removal rate. The addition mode of Fenton reagent was also modified to obtain a better organic removal rate and more cost-effective operation. With Fenton sludge recycling, 9% higher COD removal was obtained, and the sludge to be disposed could be reduced up to 50%. Also, the coagulant could be reduced by 50%. For Fenton oxidation process, stepwise addition of reagents gave a 5% higher COD removal, and a 25% reduction in chemical consumption.

In the current work, a modified heterogeneous advanced Fenton process (AFP) is presented as a novel methodology for the treatment of phenolic wastewater. The modified AFP, which is a combination of hydrodynamic cavitation generated using a liquid whistle reactor and the AFP is a promising technology for wastewaters containing high organic content. The presence of hydrodynamic cavitation in the treatment scheme intensifies the Fenton process by generation of additional free radicals. Also, the turbulence produced during the hydrodynamic cavitation process increases the mass transfer rates as well as providing better contact between the pseudo-catalyst surfaces and the reactants. A multivariate design of experiments has been used to ascertain the influence of hydrogen peroxide dosage and iron catalyst loadings on the oxidation performance of the modified AFP. Higher TOC removal rates were achieved with increased concentrations of hydrogen peroxide. In contrast, the effect of catalyst loadings was less important on the TOC removal rate under conditions used in this work although there is an optimum value of this parameter. The concentration of iron species in the reaction solution was measured at 105 min and its relationship with the catalyst loadings and hydrogen peroxide level is presented. AU - Chakinala, Anand G.

Results of two-level-factorial-design indicated that pH, COD, and the interaction of pH and COD gave negative effects, but Fe(II) dosage and H2O2/Fe(II) mole ratio showed positive effect, respectively. The quadratic model was derived based on the results of both two-level-factorial-design experiment and further runs of star points and center points.

The effects of the H2O2 dose, the pH and the organic matter concentration have been studied. The optimal experimental conditions were found to have continuous presence of iron metal, acid pH (2.0–4.0), and relatively concentrated hydrogen peroxide (9.5 M). Coloration of OMW disappeared and phenolic compound decreased to 50% of initial concentration after 3 h reaction time. The application of zero-valent Fe/H2O2 procedure permitted high removal efficiencies of pollutants from olive mill wastewater. The results show that zero-valent Fe/H2O2 could be considered as an effective alternative solution for the treatment of OMW or may be combined with a classical biological process to achieve high quality of effluent water.

The effect of operating conditions such as reaction time, pH, H2O2 to Fe(II) molar ratio, Fenton's reagent dosage, initial COD strength, feeding mode, the type of polymer, and temperature on the efficacy of Fenton process was investigated. It is demonstrated that Fenton's reagent can effectively degrade leachate organics. Fenton process was so fast that it was complete in 30 min. The oxidation of organic materials in the leachate was pH dependent and the optimal pH was 2.5. The favorable H2O2 to Fe(II) molar ratio was 1.5, and organic removal increased as dosage increased at the favorable H2O2 to Fe(II) molar ratio. The efficacy of Fenton process was improved by adding Fenton's reagent in multiple steps than that in a single step. Furthermore, the stepwise addition of both hydrogen peroxide and ferrous iron was more effective than that of hydrogen peroxide only. Sludge settling characteristics were much improved with the addition of the proper polymer. Temperature gave a positive effect on organic removal.

In addition, degradation of amoxicillin, ampicillin and cloxacillin under optimum operating conditions were evaluated. The optimum operating conditions for an aqueous solution containing 104, 105 and 103 mg/L amoxicillin, ampicillin, and cloxacillin, respectively were observed to be COD/H2O2/Fe2+ molar ratio 1:3:0.30 and pH 3. Under optimum operating conditions, complete degradation of amoxicillin, ampicillin and cloxacillin occurred in 2 min. In addition, biodegradability improved from ∼0 to 0.37 in 10 min, and COD and DOC degradation were 81.4% and 54.3%, respectively in 60 min. Maximum biodegradability (BOD5/COD ratio) improvement was achieved in 10, 20 and 40 min at antibiotics concentration 100, 250 and 500 mg/L, respectively for each antibiotic in aqueous solution. Increase in nitrate and ammonia concentration were observed due to mineralization of organic nitrogen, concentration of nitrate increased from 0.3 to 10 mg/L and concentration of ammonia increased from 8 to 13 mg/L in 60 min.

Fenton and related reactions are potentially useful oxidation processes for destroying toxic organic compounds in water. In these reactions, hydrogen peroxide is combined with ferrous or ferric iron in the presence or absence of light to generate hydroxyl radicals (OH). The feasibility of Fenton's reagent to treat waste chemicals from an academic research laboratory was investigated in this study. A response surface methodology was applied to optimize the Fenton oxidation process conditions using chemical oxygen demand (COD) removal as the target parameter to optimize, and the reagent concentrations, as related to the initial concentration of organic matter in the effluent, and pH as the control factors to be optimized. Maximal COD removal (92.3%) was achieved when wastewater samples were treated at pH 4 in the presence of hydrogen peroxide and iron in the ratios [COD]:[H2O2]=1:9 and [H2O2]:[Fe2+]=4.5:1. Under these conditions, it was possible to obtain simultaneously maximal COD removal and minimal chemical sludge after treatment, which is a residue that needs further processing.

The effects of operating conditions such as H2O2 to Fe2+ mole ratio, Fenton’s reagent dosage, initial pH, current density, inter-electrode gap and hydrogen peroxide feeding mode on COD removal was investigated. The results showed that COD removal by oxidation is dominant due to the high H2O2/Fe2+ mole ratio employed and the overall COD removal showed the same behavior as oxidation removal. The coagulation removal of COD increased with initial pH and ferrous iron dosage, but it was independent of current density and the inter-electrode gap at a fixed initial pH value and ferrous iron dose. Increasing Fenton’s reagent dosage or decreasing the initial pH is likely to promote COD removal by oxidation. There existed an optimal H2O2/Fe2+ mole ratio, current density or inter-electrode gap to reach the highest COD removal efficiency by oxidation. The stepwise or continuous addition of hydrogen peroxide was more effective to oxidize organics than a single dose of hydrogen peroxide. Nearly all the organic compounds (>4 kDa) were degraded into smaller ones after Fered–Fenton treatment. GC–MS analysis was used to determine the organic compounds before and after the treatment.

The removal efficiencies of HA by oxidation and coagulation were tested under various operating conditions: reaction time, initial pH, dosages of Fenton reagents, [H2O2]/[Fe2+] molar ratio, initial HA concentration and reaction temperature. It is demonstrated that Fenton process can effectively remove HA. The values of 27.6% mineralization of HA and 78.9% reduction of UV absorbance at 254 nm (UV254) by oxidation after 120 min reaction time indicated that HA was not completely oxidized to carbon dioxide but rather transformed to some organic intermediates. Moreover, the oxidation occurred mainly at the first 60 min and predominated the HA removal efficiency. Under the most favorable conditions (initial pH 4.0, H2O2 160 mM, Fe2+ 40 mM, reaction time 120 min, reaction temperature 30 °C), 93.3% of UV254 was reduced, the reduction of UV254 by oxidation and coagulation were 78.9% and 14.4%, respectively. Results highlighted the synergistic roles of oxidation and coagulation in Fenton treatment of HA.

The objective of the study was to quantitatively verify the feasibility of MTBE degradation with Fenton reagent under such conditions. The conclusions may be potentially helpful to further develop an effective in situ treatment of MTBE-contaminated groundwater. Initial MTBE concentrations ([MTBE]0) of 11.4 and 22.7 μM (approximately 1.0 and 2.0 mg/L, respectively) were treated with Fenton reagent (FR) using a [FR]0:[MTBE]0 molar ratio of 10:1. FR was used in equimolar mixture of Fe2+and H2O2 (i.e., [Fe2+]0:[H2O2]0=1:1). This analysis considers the hydroxyl radicals (OH) produced by FR as the main species responsible for the degradation processes. The effects of [MTBE]0 and pH on the oxidation kinetics were investigated. Under these conditions it was observed that: (i) MTBE was degraded at high extent (90–99%) after 1 h of reaction time, (ii) MTBE mineralization was low in all cases and reached only 31.7% at the best conditions, and (iii) In all cases, most of MTBE degradation occurred during the initial 3–5 min of reaction. During this brief initial phase, MTBE transformation followed pseudo-first order kinetics, while the subsequent phase exhibited a sharp drop in degradation rate and had almost negligible contribution to the overall degradation. Experiments performed at acidic pH exhibited the best degradation results, while at neutral pH the degradation rates dropped significantly. Other parameters included in this analysis were: TOC reduction and total concentration of compounds containing the tert-butyl group in their structure (tBC). These compounds were analyzed because of the concerns related to their potential toxicity. Tert-butyl formate (TBF), Tert-butyl alcohol (TBA), acetone and methyl acetate were identified and quantified as major reaction intermediates. AU - Burbano, Arturo A. AU - Dionysiou, Dionysios D.

Results show that dyes are decomposed in a two-stage reaction. In the first stage, dyes are decomposed rapidly, and somewhat less rapidly in the second stage. The effects of different system variables like initial pH of the medium, initial concentrations of the dye, Fe2+ and H2O2, reaction temperature, and added Cl− and SO4−2 ions have been investigated. The degradation rate is strongly dependent on the initial concentrations of the dye, Fe2+ and H2O2. The results indicate that the B54 and R31 can be most effectively oxidised in an aqueous medium of pH 3 at an initial [Fe2+]:[H2O2]:[dye] ratio of 1:32.9:2.4 and 1:16.5:1.8 (mM), respectively. At the optimum initial ratio of [Fe2+]:[H2O2]:[dye], 97% degradation can be achieved in 30 min at a temperature of 30 °C, and 70% removal of initial chemical oxygen demand (COD) is achieved after 60 min. The degradation of both the dyes obeys first order rate kinetics with respect to the concentration of the dye in the second stage of oxidation. The results will be useful in designing wastewater treatment plants. AU - Malik, P. K. AU - Saha, S. K.

Different mass ratios of Fe2+/H2O2 recorded the percentage COD reduction from 54 to 80 % in 4 h at pH 3.5. The batch study has established COD reduction by 82 % with mesoporous activated carbon (MAC800) catalyst and the percentage reduction of COD was 94 % under integrated homo- and hetero-Fenton oxidations of tannery wastewater. Fenton reagent was efficient enough to oxidize most of the organic compounds present in the tannery wastewater. This was confirmed through UV–visible spectroscopy, FT-IR spectroscopy, cyclic voltammetry and NMR spectroscopy. AU - Sekaran, G. AU - Karthikeyan, S. AU - Evvie, C. AU - Boopathy, R.

To enhance the oxidation power of Fenton's reagent, it was assisted photochemically (photo-Fenton) or electrochemically (electro-Fenton). Kinetic analysis showed that the oxidation of diuron by hydroxyl radicals follows a reaction kinetic of pseudo-first order. The apparent rate constants values and mineralization degree of different photochemical processes revealed the superiority of the photo-Fenton process in degradation rate (kinetics) and that of electro-Fenton process in cost effectiveness and process efficiency. The absolute rate constant for diuron oxidation by hydroxyl radical was determined as (4.75 ± 0.20) × 109 L mol−1 s−1 by competition kinetics method taking benzoic acid as reference compound. Electro-Fenton process exhibits a very fast degradation kinetics achieving complete removal of 0.17 mM diuron in less than 6 min. The apparent current efficiency was determined; its maximum value of 28% at 0.6 h decreases with the treatment time to 11% at 3 h, i.e., when 89% of mineralization is achieved. When 300 mA was applied, higher mineralization efficiency of 96% was achieved. The photo-Fenton process exhibits also high mineralization efficiency reaching 97% TOC removal at 5 h under optimal operating conditions. Several oxidation by-products such as 3,[3,4-dichlorohydroxyphenyl]-1,1-methylurea, 3,[3-hydroxy 4-chlorohydroxyphenyl]-1,1-methylurea, 3-[trihydroxyphenyl]-1,1-dimethylurea, 3,[3-hydoxy-4-chlorophenyl]-1,1-methylurea, 3,[3-hydroxy-4-chlorophenyl]-1,1-dimethylurea, and dichloroaniline were identified by HPLC and LC–MS analyses evidencing two sites of attack of hydroxyl radical, the first being located on the aromatic ring and the second on the dimethylurea group. Based on the identification of aromatic intermediates, carboxylic acids and chloride ion released; a plausible diuron mineralization pathway is proposed. AU - Oturan, Mehmet A.

Beyond the most abundant benzenediols, the pattern of aromatic intermediates was chiefly characterized by hydroxylated biphenyls and diphenyl ethers with different degrees of hydroxylation. Hydroxylated dibenzofurans (DBF), p,p′-dioxins, as well as highly condensed aromatic intermediates including polyols of polycyclic aromatic hydrocarbons (PAHs), could also be detected, but in lower concentrations. The formation of aromatic intermediates could be predicted on the basis of oxidative coupling reactions of resonance-stabilized radicals generated by the attack of the highly reactive hydroxyl radicals (OH*) on phenol. GC/MS identification of oxidative coupling intermediates was performed after derivatization of the solvent extracts. Derivatization reactions included silylation to give TMS (trimethylsilyl) ethers, as well as single-step extractive acetylation using acetic anhydride in alkaline aqueous solutions (pH 10.5) to give acetates. Solvent extraction of aqueous solutions, a prerequisite to generate TMS ethers, caused strong discrimination of polyols due to their low distribution coefficients in non-polar solvents. This discrimination could be overcome by extracting the in-situ formed acetates of the intermediates. Extractive acetylation allowed the detection of tri-, tetra-, and penta-hydroxylated aromatic intermediates generated by Fenton oxidation processes, which have been overlooked upto now. Thus, extractive acetylation to detect stable aromatic intermediates covering a wide range of hydroxylation degrees can foster the understanding, monitoring, and management of advanced oxidation processes, especially in the field of wastewater treatment.

The rate of accumulation of carbonyl-containing products of the protein fragmentation, detected as 2,4-dinitrophenylhydrazones, is independent of the pH of the reaction medium and proportional to the concentrations of hydrogen peroxide, ferrous ion, and hemoglobin. A chain radical mechanism of the peroxide fragmentation of the polypeptide chains of hemoglobin has been proposed, involving reactions of the alkoxyl radical of hemoglobin with ferrous ion and of the carbon-centered radical of the protein with dissolved oxygen as rate-limiting steps. Chain termination is therewith effected through cross recombination of the above radicals. AU - Lukogorskaya, S. A. AU - Shugalei, I. V. AU - Tselinskii, I. V.

Promising removal technologies of chlorinated aromatics consist in the application of advanced oxidation processes (AOPs) that can provide an almost total degradation of a variety of contaminants. Among these, wide application find Fenton systems based on generation of reactive species having a high oxidizing power, such as hydroxyl radical HO•. Our objective was that of determining the overall degradation efficiency of the model compound 2,4-dichlorophenol (DCP) by thermal Fenton-type oxidation systems with a view toward defining in more details relevant process parameters, the effect of reaction temperature and of co-catalyst Cu2+. Methods Reaction conditions were similar to those generally adopted as optimal in many practical applications, i.e. pollutant /Fe2+ (as FeSO4) ratio ca. 20, Fe2+/Cu2+ (co-catalyst) 2:1, pH adjusted and controlled at pH 3, and H2O2 in excess (up to four-fold over the stoichiometric amount required for complete mineralization). Results and Discussion The results demonstrate that it is advantageous to carry out the reaction at a temperature markedly higher (70°C) than ambient. The stepwise addition of H2O2 in aliquots yields an efficient transformation, while allowing a convenient control of the reaction exothermicity. Under these conditions, the essentially complete removal of the initial DCP is accomplished using just one equiv of H2O2 during 15 min; excess H2O2 (5 equivalents) yields extensive substrate mineralization. Also relevant, at 70°C dechlorination of the initial DCP (and of derived reaction intermediates) is remarkably extensive (3-5% residual TOX), already with the addition of 1 equiv of H2O2. At the end of the reaction, IC and IC-MS analyses of the solution reveal that only low-molecular weight carboxylic acid (acetic, formic, oxalic, malonic, tartaric, etc.) contribute to the residual TOC. Conclusions The whole of the results herein point to the advantage of performing the process at temperatures substantially higher than ambient (70°C). Under the conditions adopted, almost complete degradation of the initial toxic compound can be achieved using hydrogen peroxide in fair excess (e.g., 3.5 equiv H2O2). Recommendations and Outlook In applying practical Fenton-type degradation systems to heavily polluted wastes, either for the pre-treatment of waters with a high COD value prior to biodegradation or for complete mineralization of pollutants, the set up of appropriate reaction conditions appears to be a key factor. Also, it is desirable to keep the concentration of iron salts within the lower limits in order to minimize the production and disposal of iron oxide sludges.

The experimental variables studied include dosages of iron salts and hydrogen peroxide, oxidation time, mixing speed and organic content. The results show that color was removed mainly by Fenton oxidation. The color removal reached a maximum of 90% at a reaction time of 5 min under low dosages of H2O2 and Fe2+. In contrast, the COD was removed primarily by Fenton coagulation, rather than by Fenton oxidation. The ratio of removal efficiency between Fenton process and ferric coagulation was 5.6 for color removal and 1.2 for COD removal. It is concluded that Fenton process for the treatment of textile wastewater favors the removal of color rather than COD.

The parameters influencing the COD removal of the wastewater, namely temperature, ferrous ion and hydrogen peroxide concentrations have been optimized to achieve a COD global reduction of 56.4%. The total range of the proposed experimental design, however, could not be tested because under some conditions (hydrogen peroxide concentration over 5 M) the Fenton’s reaction became violent and could not be controlled, probably due to the high exothermic effect associated with COD oxidation. For the tested conditions, the optimal values of hydrogen peroxide and ferrous ion concentration were 3 and 0.3 M, respectively, whereas temperature only showed a mild positive effect on COD removal. In addition, during the first 10 min of Fenton’s reaction, more than 90% of the total COD removal can be achieved. Fenton’s reaction has proved to be a feasible technique for the pre-oxidation of the wastewater under study, and can be considered a suitable pre-treatment for this type of wastewaters.

The operation conditions were as follows: H2O2 and ferrous dosages were 100–800 mg/L; pH value was 1–7; reaction time was 0.5–4.0 h. In terms of COD removal and biodegradability improvement, the optimal conditions were as follows: ferrous content was 300 mg/L; hydrogen peroxide was 500 mg/L; pH value was 3.0; reaction time was 2 h. With these conditions, the overall COD removal and effluent B/C could arrive at 65.5% and 0.529 respectively. The biodegradability of the acrylic fiber manufacturing wastewater was increased by 429%. It was unnecessary to achieve complete mineralization of the organic compounds into carbon dioxide and water. Partial oxidation of intermediate compounds could minimize the consumption of chemical reagents and result in substantial reduction of COD and toxicity. The further biological treatment was favored by acquiring degradable low molecular weight components.

The effects of operating parameters including the Fenton reagent dosage, the initial pH value, and the reaction time on the treatment efficiencies of the Fenton oxidation process were observed. About 47.0% of the chemical oxygen demand (COD) removal efficiency was reached under the optimum conditions: hydrogen peroxide of 90.0 mM, ferrous ions of 20.0 mM, pH value of 3.0, and reaction time of 120 min. The COD degradation of the Fenton process followed the pseudo first-order reaction kinetics, and the apparent activation energy E, was determined to be 41.6 kJ mol-1. After the Fenton pretreatment under the optimum reaction conditions, the BOD5/COD ratio of wastewater increased from 0.32 to 0.69, which was suitable for further biological treatment. The improvement of biodegradability was attributed to the removals of aromatics and some other bio-refractory compounds from the wastewater, as confirmed by gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FTIR) and fluorescence excitation-emission matrix (EEM) spectroscopy analyses. Fenton process was proven to be an effective method for the pretreatment of DAF manufacturing wastewater prior to biological treatment.

Both samples presented high organic load, high toxicity and low biodegradability. These were the reasons why oxidative treatment was proposed. Fresh and mature leachate showed different behaviors in the oxidation experiments. The final extents of removal were attained in comparable time intervals in both oxidation systems. Maximal removal of organics by the Fenton’s oxidation reached more than 50 % according to COD. Zero or first order kinetics were found the best to describe the organic components (in terms of COD and DOC) removal by the Fenton’s oxidation for both landfill leachates. Higher reaction rate values of the Fenton’s oxidation were achieved with fresh leachate samples. The efficiency of initial organics removal with ozone was about 70 % for mature leachate, while in case of the fresh one only 41 % of COD were removed. The best fits of COD and DOC experimental data from oxidation of fresh and mature leachates were obtained by a combined kinetic model. No significant improvement of the biodegradability of landfill leachates was achieved using these treatment procedures. Regarding toxicity, ozonation showed to be more effective than the Fenton’s oxidation. Advanced oxidation experiments confirmed that the Fenton’s oxidation and ozonation are comparable oxidative treatment techniques for the reduction of organic pollution in the investigated municipal landfill leachates. However, neither of them is effective enough to be used as a pretreatment method followed by biological treatment.

The optimum removal of total suspended solids (TSSs, 81%) by chitosan coagulation was achieved at actual pH (4.3) for 400 mg L−1 coagulant dose. The maximum organic matter removals by F (85%) and PF (95%) processes were achieved after 2.0 and 1.0 h, respectively by using 15,000/1852 (w/w) ratio of H2O2/FeSO4. On the opposite, in PC experiments, after an initial decrease in the early minutes of the treatment, a subsequent increase versus irradiation time was observed for both UV absorbance at 280 nm and chemical oxygen demand (COD); probably a partial oxidation made some organics detectable only after treatment.

On the other hand, acute toxicities of raw, physicochemical pre-treated, and Fenton and Fenton-like oxidations applied samples of OOMW on activated sludge microorganisms using respiration inhibition test (ISO 8192) are presented. Chemical pre-treatment (acid cracking and coagulation–flocculation) positively affected the biodegradability and inhibition on activated sludge was considerably removed (>67% COD and >72% total-phenol removal). Fenton and Fenton-like processes showed high COD (>80%) and total-phenol (>85%) removal performance on evaluated effluents. Inhibitory effect of Fenton-like reagents applied samples on activated sludge mixture was considerably removed. In addition to the toxicity, total-phenol and COD removal efficiencies of applied processes, their associated operating costs were also determined in this paper.

Hydroxyl radical formation rate and time dependent concentration were determined in pure water, in aqueous fulvic acid (FA) and humic acid (HA) solutions, and in natural surface waters. Indirect determinations of hydroxyl radical were made by quantitating hydroxyl radical reactions with probe compounds under controlled conditions. High probe concentrations were used to determine radical formation rates and low probe concentrations were used to determine time dependent radical concentration. Two independent probes were used for intercomparison: benzoic acid and 1-propanol. Good agreement between the two probes was observed. Natural water matrices resulted in lower radical formation rates and lower hydroxyl radical concentrations, with observed formation rate and yield in natural waters up to four times lower than in pure water. HA and FA also reduced hydroxyl radical formation under most conditions, although increased radical formation was observed with FA at certain pH values. Hydroxyl radical formation increased linearly with hydrogen peroxide concentration. AU - Lindsey, Michele E. AU - Tarr, Matthew A.

The aim of this study was to review the recent developments mainly in UV/H2O2 process and Fenton’s reactions. Ultraviolet (UV) radiation is an essential factor in photochemical oxidation. In the development of UV radiation sources the energy efficiency and the use of toxicant free materials have become major objectives. Also the emitted wavelength plays a significant role. Besides, there are alternatives for UV radiation sources, such as radio frequency (RF) plasmas, which can operate in water without additional chemicals. A remarkable development in the field of chemical oxidation has been novel catalyst materials for Fenton’s reaction enabling the efficient reaction in neutral or almost neutral conditions, instead of pH below 3. In addition, varieties of method integrations, e.g., combinations of AOPs or AOPs integrated to biological processes, and other enhancements such as combining ultrasound (US) with AOP have led to improved water treatment efficiencies.

In this paper, COD reduction potential of leather tanning industry wastewaters by Electro-Fenton (EF) oxidation, as one of the AOPs, was experimentally evaluated. The wastewater sample was taken from an outlet of an equalization basin in a common treatment plant of an organized tannery industrial region in Istanbul, Turkey. Treatment of the wastewater was carried out by an electrochemical batch reactor equipped with two iron electrodes, which were connected parallel to each other. The oxidation process was studied for optimization of H2O2 and the electricity consumptions were observed at different contact times under different pH conditions (3.0, 5.0 and 7.2). In each case, electricity consumption for decreased COD mass was estimated. In this process, COD was reduced by 60–70% within 10 min. By taking into consideration the local sewerage discharge limit, applicability of EF process for the tannery wastewaters was evaluated. AU - Kurt, Ugur AU - Apaydin, Omer AU - Gonullu, M.

Advanced treatment methods including Fenton process, polyaluminium chloride (PAC) coagulation and ion exchange were applied on OID effluent. In Fenton process removal efficiencies for suspended solids (SS), chemical oxygen demand (COD), SAC436 (spectral absorption coefficient), SAC525 and SAC620 were determined 61%, 36%, 35%, 49% and 67%, respectively. After Fenton process, wastewater samples were coagulated with PAC. Optimum removal efficiencies for SS, COD, Fe ion, SAC436, SAC525 and SAC620 were determined 83%, 18%, 93%, 32%, 36% and 58%, respectively. Ion exchange experiments were conducted on chemically coagulated wastewater samples to improve the quality of wastewater. Optimum dosage of resins was determined. The experiments revealed that 1:1 resin ratio (20 mL H-type resin:20 mL OH-type resin) gave the best removal rates for the parameters considered in this study.

To establish cost-efficient operating conditions for the application of Fenton's reagent, the effects of operating conditions such as the dosages of H2O2, the molar ratio of [Fe2+]/[H2O2], the value of solution pH and the system temperature on the removal of COD were evaluated systematically.

A kinetic study was carried out using a modified pseudo-first-order model. The results showed the COD removal for bleaching effluents by Fenton's reagent followed the first-order reaction kinetics, and the activation energy Ea was detected to be 1.68 kJ mol−1 based on the experiments performed at different temperatures. In addition, the results of GC/MS analysis showed organic pollutants in effluents were degraded into organic acids of lower molecular weight under the attack of hydroxyl radicals generated in Fenton's reaction.

Experimental procedure is performed with diluted OMW with COD 19 g/L and pH 5.2. The application of zero-valent Fe/H2O2 procedure allows high removal efficiency of pollutants from OMW. The optimal experimental conditions were found to be continuous presence of iron metal, acidic pH (2–4) and 1 M hydrogen peroxide solution. The experimental results show that the removal of 1 g of COD need 0.06 M of H2O2. At pH 1, the maximum COD removal (78%) is achieved after 1 h. Therefore, with a pH value within 2 and 4 the maximum COD removal reached 92%. Phenolic compounds are identified in treated and untreated OMW by gas chromatography coupled to mass spectrometry (GC–MS).

Still H2O2 alone is not effective for high concentrations of certain refractory contaminants because of low rates of reaction at reasonable H2O2 concentrations. Improvements can be achieved by using transition metal salts (e.g. iron salts) or ozone and UV-light can activate H2O2 to form hydroxyl radicals, which are strong oxidants. Oxidation processes utilising activation of H2O2 by iron salts, classically referred to as Fenton’s reagent is known to be very effective in the destruction of many hazardous organic pollutants in water. The first part of our paper presents a literature review of the various Fenton reagent reactions which constitute the overall kinetic scheme with all possible side reactions. It also summarises previous publications on the relationships between the dominant parameters (e.g. [H2O2], [Fe2+], …). The second part of our review discusses the possibility of improving sludge dewaterability using Fenton’s reagent. AU - Neyens, E. AU - Baeyens, J.

It has been observed that none of the methods can be used individually in wastewater treatment applications with good economics and high degree of energy efficiency. Moreover, the knowledge required for the large-scale design and application is perhaps lacking. In the present work, an overview of hybrid methods (the majority are a combination of advanced oxidation processes) has been presented. Hybrid methods viz Ultrasound/H2O2 or ozone, UV/H2O2 or ozone, Ozone/H2O2, Sono-photochemical oxidation, Photo–Fenton processes, catalytic advanced oxidation processes, use of advanced oxidation processes in conjunction with biological oxidation, SONIWO (sonochemical degradation followed by wet air oxidation), and CAV-OX have been discussed with specific reference to the principles behind the expected synergism, different reactor configurations used and optimum considerations for the operating and geometric parameters. An overview of different chemicals degraded has been presented. Some of the important works evaluating the application of these processes to real effluents have been described in detail. Some guidelines for the future work required to facilitate efficient large-scale operation have been given. A model effluent treatment scheme based on the various techniques discussed in the present work has been presented. AU - Gogate, Parag R. AU - Pandit, Aniruddha B.

The influence of the main operating parameters, Fe(II) concentration (5.0×10−5 to 4.0×10−4 M), pH (2–6) and temperature (10–30 °C) has been studied. Based on HPLC analysis, the main route of simazine removal has been proposed to be the dechlorination reaction to generate 2-hydroxy-4,6-bis(ethylamino)-s-triazine. Nevertheless the dealkylated first intermediate of the herbicide was also identified by chromatography techniques. By means of a pseudoempirical model based on the classic Fenton’s chemistry and the mass balances for a continuos perfectly mixed reactor, the theoretical evolution profiles of the species involved in the process have been calculated.

This methodology is suitable for application in small treatment and remediation facilities. Reagent concentrations of H2O2 and Fe2+ were found to influence the reaction time and temperature, as well as the degree of mineralization and biodegradability of the sample contaminants. Some H2O2/Fe2+ combinations (H2O2 greater than 10% and Fe2+ greater than 50 mM) resulted in a strong exothermic reaction, which causes peroxide degradation and violent gas liberation. Up to 75% TOC removal efficiency was attained in water and 70% in soil when high H2O2 (20%) and low Fe2+ (1 mM) concentrations were used. Besides increasing the degree of mineralization, the Fenton's reaction enhances the biodegradability of petroleum compounds (BOD5/COD ratios) by a factor of up to 3.8 for contaminated samples of both water and soil. Our experiments showed that low reagent concentrations (1% H2O2 and 1 mM Fe2+) were sufficient to start the degradation process, which could be continued using microorganisms. This leads to a decrease in reagent costs in the treatment of petroleum-contaminated water and soil samples. The simple measurements of H2O2 concentration or CO2 evolution were effective to evaluate the Fenton's reaction efficiency. AU - Mater, L. AU - Rosa, E. V. C. AU - Berto, J. AU - Corrêa, A. X. R.

Some parameters, like temperature, initial concentrations of Fe(II) and H2O2 and the use of natural or artificial light were evaluated aiming to find the optimal conditions to promote the efficient degradation of the dyes. The experimental results showed that the Fenton's process run under solar light was the most effective. Pseudo-first order degradation rate constants were obtained from batch experimental data. It is suggested that Fenton's and photo-Fenton's type reactions are viable techniques for the treatment of such types of reactive dyes, according to the high levels of colour, aromatic content (UV254) and DOC removal.

The experiments were conducted in six different operating modes. For all tests, total dosage of ferrous (Fe2+) salt and hydrogen peroxide (H2O2) was kept at 2000 mg L− 1 and 4000 mg L− 1, respectively and the total reaction time was maintained at 160 min. The kinetics of the decomposition of organic matter in terms of dissolved chemical oxygen demand (DCOD) by H2O2 followed the pseudo-first order reaction. For DCOD decomposition, the removal rate constant equation of DCOD, k1 = 2.95 × 10− 6[H2O2]00.17[Fe2+]01.60 was obtained, where k1 is the reaction rate coefficient of DOCD decomposition. The consumption rate constant equation of H2O2, k2 = 1.85 × 10− 3[H2O2]0− 1.70[Fe2+]02.90 was obtained, where k2 is the reaction rate coefficient of hydrogen peroxide consumption. Batch and semi-batch studies indicated that oxidation with Fenton's reagent is feasible for treating ABS wastewater. AU - Popuri, Srinivasa R.

A temperature dependent kinetic model for the hv/Fe(III)/H2O2 system, incorporating 12 major reactions with no fitted rate constants or activation energies, was developed, and successfully explained the experimental measurements. Particularly, the thermal enhancement of Fe(OH)2+ photolysis which is the most significant step in the hv/Fe(III)/H2O2 system was effectively explained by two factors; (1) the variation of the Fe(OH)2+ concentration with temperature, and (2) the temperature dependence of the quantum yield for Fe(OH)2+ photolysis (measured activation energy=11.4 kJ mol−1). Although in both the hv/Fe(III)/H2O2 and Fe(III)/H2O2 systems, elevated temperatures enhanced the formation of OH, the thermal enhancement was much higher in the dark Fe(III)/H2O2 system than the hv/Fe(III)/H2O2 system. Furthermore, it was found that the relative thermal enhancement of the formation of OH in the presence of OH scavengers (tert-butyl alcohol) was magnified in the Fe(III)/H2O2 system but was not in the hv/Fe(III)/H2O2 system.

Binders and other additives may also affect the toxicity of the paint depending on the specific characteristics of the paint. This study deals with Water-based paint wastewater, which is hard to treat. Fenton oxidation process was principally used to treat the wastewater. Treatability runs were carried out by using rust (oxidized iron) particles obtained as a waste of the metal rolling process, as the Fenton’s catalyst. In order to change the variables such as dimensions of the column, packing material size, reactive dosage, pH value and reaction time, the experiments on the basis of packed columns and mixed reactors were carried out to increase the COD removal. COD eliminations with pH adjustment were about 20%. With the contribution of Fenton process in both column and mixed-reactor studies, the COD removal was improved by about 80%.

Particular attention was paid to the effect of initial pH, dosage of H2O2 and to improvement in biodegradation. The results showed that higher COD and total phenol removal rates were achieved with a decrease in initial pH and an increase in H2O2 dosage. At an initial pH of less than 6.5 and H2O2 concentration of 0.3 M, COD removal reached 44–50% and approximately 95% of total phenol removal was achieved at a reaction time of 1 h. The oxygen uptake rate of the effluent measured at a reaction time of 1 h increased by approximately 65% compared to that of the raw coking wastewater. This indicated that biodegradation of the coking wastewater was significantly improved. Several organic compounds, including bifuran, quinoline, resorcinol and benzofuranol were removed completely as determined by GC–MS analysis. The advanced Fenton oxidation process is an effective pretreatment method for the removal of organic pollutants from coking wastewater. This process increases biodegradation, and may be combined with a classical biological process to achieve effluent of high quality.

Semi-batch experiments in the LWR were designed to investigate the performance of the process for two different industrial wastewater samples. The effect of various operating parameters such as pressure, H2O2 concentration and the initial concentration of industrial wastewater samples on the extent of mineralization as measured by total organic carbon (TOC) content have been studied with the aim of maximizing the extent of degradation. It has been observed that higher pressures, sequential addition of hydrogen peroxide at higher loadings and lower concentration of the effluent are more favourable for a rapid TOC mineralization. In general, the novel combination of hydrodynamic cavitation with AFP results in about 60–80% removal of TOC under optimized conditions depending on the type of industrial effluent samples. The combination described herein is most useful for treatment of bio-refractory materials where the diminution in toxicity can be achieved up to a certain level and then conventional biological oxidation can be employed for final treatment. The present work is the first to report the use of a hydrodynamic cavitation technique for real industrial wastewater treatment. AU - Chakinala, Anand G. AU - Gogate, Parag R. AU - Burgess, Arthur E.

The combined process consisted of chemical coagulation, hydrolysis/acidification and Fenton oxidation. Chemical coagulation treatment with polymeric ferric sulfate (PFS)/lime alone proved to be effective in removing the COD (>70%) and part of the color (>50%) from the JWW. Fenton oxidation combined with hydrolysis/acidification as pretreatment offered a noticeable BOD removal efficiency. The average removal efficiencies for COD, BOD, SS, color and aromatic compounds of the combined process were about 95%, 94%, 97%, 95% and 90%, respectively, with the average effluent quality of COD 58 mg/L, BOD 19 mg/L, SS 4 mg/L and color 15(multiple), consistent with the national discharge limits for textile wastewater. The result indicated that the combined procedure could offer an attractive solution for JWW treatment with considerable synergistic advantages.

In addition, the process can increase the biodegradable fraction of organic constituents in leachate, particularly in mature or biologically recalcitrant leachate. Oxidation and coagulation both play important roles in the removal of organics. Initial pH, dosages of Fenton reagents, aeration, final pH, reagent addition mode, temperature, and UV irradiation may influence final treatment efficiency. In this paper, current knowledge of performance and economics of Fenton processes for treatment of landfill leachate as reported for laboratory, pilot and full-scale studies is reviewed, with the conclusion that the Fenton process is an important and competitive technology for the treatment or pretreatment of landfill leachate.

The sole treatment by Fenton's oxidation involving the introduction of 6 g FeSO4 and 266 g H2O2 in a liter of wastewater at pH of 3.5 and 30 °C for 30 min at batch conditions reduced COD, BOD5, sulfide, total chromium and color up to 69%, 72%, 88%, 5%, 100% and T. ferrooxidans alone showed maximum reduction to an extent of 77, 80, 85, 52, 89, respectively, in 21 d treatment at pH 2.5, FeSO4 16 g/L and temperature of 30 °C. The combined treatment at batch conditions involving 30 min chemical treatment by Fenton's oxidation followed by 72 h biochemical treatment by T. ferrooxidans at batch conditions gave rise up to 93%, 98%, 72%, 62% and 100% removal efficiencies of COD, BOD, sulfide, chromium and color at pH of 2.5 and 30 °C.

Typical operating variables such as reagent concentration (CH2O2 = 1.0?0.2 M; CFe(II) = 0.01?0.1 M) and temperature (T = 293?323 K) exerted a positive influence on the chemical oxygen demand and total carbon removal. The optimum working pH was found to be in the range 2.5?3.0. The exothermic nature of the process involved a significant increase of the temperature of the reaction media. The process was well simulated by a semiempirical reaction mechanism based on the classic Fenton chemistry. From the model, the reaction between ferric iron and hydrogen peroxide [k = 1.8 ? 1015 exp((?12577 ± 1248)/T)] was suggested to be the controlling step of the system. Also, the simultaneous inefficient decomposition of hydrogen peroxide [k = 6.3 ? 1012 exp((?11987 ± 2414)/T)] into water and oxygen was believed to play an important role in the process. On the basis of stoichiometric calculations for hydrogen peroxide consumption, an estimation of the process economy has been completed.

The process efficiency which depends on several important process parameters such as initial pH, iron catalyst and oxidant concentration, and the UV irradiation type, was investigated. To consider the combined effects of studied process parameters, three-factor three-level Box–Behnken experimental design combined with response surface modeling was applied. The quadratic models predicting the mineralization of simulated industrial wastewater by the applied photo-Fenton processes were developed. ANOVA was applied to evaluate the significance of models and models’ components. The obtained results indicated that both models can be characterized as highly accurate and predictive for the mineralization of simulated industrial wastewater. Our results show that both photo-Fenton processes can be successfully applied for the treatment of the studied simulated industrial wastewater. The presence of oxalates in simulated industrial wastewater strongly influenced the conditions for the maximal efficiency of applied photo-Fenton processes regarding the type of UV irradiation. The optimal conditions were determined to be: initial pH 3.88, [Fe2+] = 5.01 mM (along with [Fe3+] = 8.0 mM) and [H2O2] = 30 mM in the case of photo-Fenton process operated with UV-C irradiation; and pH 1.9, [Fe2+] = 8.39 mM (along with [Fe3+] = 8.0 mM) and [H2O2] = 30 mM in the case of UV-A light application. The “pseudo”-second order mineralization kinetic of simulated industrial wastewater was determined in both cases with the calculated rate constants at determined optimal conditions: k1obs = 12.94 × 10−2 M−1 s−1 and k2obs = 9.71 × 10−2 M−1 s−1 for UV-C/Fe/H2O2 and UV-A/Fe/H2O2 processes, respectively.

In Part I of the study, the optimal conditions for each of applied photo-Fenton processes (UV-C/Fe/H2O2 and UV-A/Fe/H2O2) were determined and used in this study for model development and verification. The mechanistic model simulates the influence of various factors: the type of UV irradiation, the changes in concentrations of pollutants, catalysts and oxidant, on photo-Fenton process performance. pH dependent equilibrium of ferrous, ferric, oxalate and formate species was simulated as well. The model was tested to evaluate its accuracy in predicting the system behavior at different pollutant concentrations. Good agreement of the data predicted by model and the empirically obtained values was confirmed by calculated standard deviation for each experimentally monitored parameter. The developed mechanistic model describing the behavior of photo-Fenton process treating simulated wastewater can be characterized as interpretable, transparent, flexible and accurate. The comparison of electrical energy costs for each of the studied processes was performed. The obtained results indicate that the process using UV-C source is more efficient and cheaper. However, the simulation of process effectiveness using the solar UV-A irradiation recorded at annual basis for the location of proposed wastewater treatment plant speaks in the favor of solar UV-A/Fe/H2O2 process application instead of artificial UV irradiation.

The influence of parameters such as the presence of NaCl and starch was evaluated and optimal iron and H2O2 dosage determined. Complete decolorization of Remazol Red RR was achieved at all investigated NaCl and starch concentration. Mineralization, in terms of COD reduction, was 96% in the homogeneous and 93% in the heterogeneous reaction, but decreased with increasing NaCl and starch concentrations. The homogeneous oxidation showed the highest efficiency in treating synthetic wastewater containing Remazol Blue RR or a mixture of Remazol Red RR and Remazol Blue RR. Nevertheless, the mineralization was significantly lower than for Remazol Red RR, which shows the dependence on dye structure. Similar amounts of iron-containing sludge were produced in the two processes, while the release of iron ions was reduced by 50% when using heterogeneous photo-Fenton. Promising results were obtained when reusing the iron powder as catalyst; complete decolorization was achieved during 20 batches. AU - Punzi, M. AU - Mattiasson, B. AU - Jonstrup, M.

The experimental design methodology was first applied to the chemical oxidation process in order to determine the values of temperature, ferrous ion concentration and hydrogen peroxide concentration that maximize dissolved organic carbon (DOC) and colour removals and increase the effluent's biodegradability. Additional studies on the biological oxidation (SBR) of the raw and previously submitted to Fenton's oxidation effluent had been performed during 15 cycles (i.e., up to steady-state conditions), each one with the duration of 11.5 h; Fenton's oxidation was performed either in conditions that maximize the colour removal or the increase in the biodegradability. The obtained results allowed concluding that the combination of the two treatment processes provides much better removals of DOC, BOD5 and colour than the biological or chemical treatment alone. Moreover, the removal of organic matter in the integrated process is particularly effective when Fenton's pre-oxidation is carried out under conditions that promote the maximum increase in wastewater biodegradability.

The effect of time, pH, H2O2 concentration, FeSO4.7H2O concentration and the mass of mesoporous activated carbon on the degradation of organics in the wastewater were critically examined. The kinetic constants and the thermodynamic parameters for the oxidation of organics in wastewater were determined. The quantitative removal of COD, BOD and TOC from the wastewater was evaluated.

Parameters affecting the Fenton process, such as pH, dosages of Fenton reagents and the settling time, were determined by using jar test experiments. 86.4% of color and 92.4% of chemical oxygen demand (COD) could be removed at pH 4, 50 mg/l H2O2, 25 mg/l FeSO4 and 30 min settling time. The coagulation using polyaluminium chloride (PAC) and ferrous sulfate (FeSO4) was beneficial to improve the Fenton process treated effluent in reducing the flocs settling time, enhancing color and COD removal. The overall color, COD and suspended solids (SS) removal reached 100%, 93.4% and 87.2% under selected conditions, respectively. Thus this study might offer an effective way for wastewater treatment of water-based ink manufacturer and printing corporation.

Conventional wastewater treatment processes are inefficient for the removal of these types of toxic and hazardous pollutants from wastewater. Electro Fenton is one of the powerful and environmentally friendly emerging technologies for the remediation of wastewaters containing organic, especially aromatic compounds. This paper reviews the fundamentals and recent developments in electro Fenton process. Electro Fenton process utilizes different electrolytic reactors such as bubble reactor, filter press reactor, divided double-electrode electrochemical cell, divided three-electrode electrochemical cell and double compartment cell. Different cathodes as working electrode and anodes as counter electrode used in this process are analyzed. The effects of various operating parameters and their optimum ranges for maximum pollutant removal and mineralization are reviewed. Also various pollutants removed by this process are evaluated. Quick removal and mineralization of pollutants and their intermediate reaction products were reported. AU - Nidheesh, P. V. AU - Gandhimathi, R.

The wastewater was originated from a factory producing a variety of pharmaceutical chemicals. Treatability studies were conducted under laboratory conditions with all chemicals (having COD varying from 900 to 7000 mg/L) produced in the factory in order to determine the operational conditions to utilize in the full-scale treatment plant. Optimum pH was determined as 3.5 and 7.0 for the first (oxidation) and second stage (coagulation) of the Fenton process, respectively. For all chemicals, COD removal efficiency was highest when the molar ratio of H2O2/Fe2+ was 150–250. At H2O2/Fe2+ ratio of 155, 0.3 M H2O2 and 0.002 M Fe2+, provided 45–65% COD removal. The wastewater treatment plant that employs Fenton oxidation followed by aerobic degradation in sequencing batch reactors (SBR), built after these treatability studies provided an overall COD removal efficiency of 98%, and compliance with the discharge limits. The efficiency of the Fenton's oxidation was around 45–50% and the efficiency in the SBR system which has two reactors each having a volume of 8 m3 and operated with a total cycle time of 1 day, was around 98%, regarding the COD removal.

The optimal conditions for Fenton reaction were found at a ratio [Fe2+]/[COD]0 equal to 0.1. Both leachates were significantly oxidized under these conditions in terms of COD removal (77 and 75% for leachate from wastewater sludge composting and leachate from organic fraction of municipal solid wastes, respectively) and BOD5 removal (90 and 98% for leachate from wastewater sludge composting and leachate from organic fraction of municipal solid wastes, respectively). Fenton's reagent was found to oxidize preferably biodegradable organic matter of leachate. In consequence, a decrease in the biodegradability of leachates was observed after Fenton treatment for both leachates. Nevertheless, Fenton reaction proved to be a feasible technique for the oxidation of the leachate under study, and it can be considered a suitable treatment for this type of wastewaters.

A stoichiometric coefficient for the Fenton reaction was found to be 0.5 mol of organic compound/mol of hydrogen peroxide, except for the formic acid where a value of approximately one was obtained (due to the direct formation of carbon dioxide). The treatment eliminates the toxic substances and increases the biodegradability of the treated water (measured as the ratio BOD5/COD). Biodegradability is attained when the initial compound is removed. AU - Chamarro, E. AU - Marco, A. AU - Esplugas, S.

The experimental part incorporated the following three schemes: biological treatment only (stage 1), chemical oxidation prior to biological treatment (stage 2), and biological treatment followed by chemical oxidation (stage 3). Biodegradation was accomplished employing three identical sequencing batch reactors (SBRs), each having a liquid volume of 10 L, while chemical treatment involved the addition of Fenton’s reagent in the range 25–300 mg/L, in a batch-type operation. Following an acclimation period of approximately 60 days, biological treatment resulted in a high percent reduction in chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), and total phosphorus (TP), and in a moderate decrease in color. The process was found to be independent of the variations in the anoxic time period studied; however, an increase in solids retention time (SRT) improved COD and color removal, although it reduced the nutrient (TKN and TP) removal efficiency. Furthermore, both combined treatment alternatives resulted in enhanced color reduction, in comparison to stage 1. Overall, chemical oxidation prior to biological treatment (stage 2) appears to be the best option regarding the treatment of the textile wastewater used. AU - Fongsatitkul, P. AU - Elefsiniotis, P.
