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.

AB - This study evaluates the effectiveness of Fenton's oxidation (FO) process and ozone (O3) oxidation compared with a coagulation–flocculation (CF) process to remove effluent toxicity as well as colour and COD from a textile industry wastewater. 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.

AB - Removal of simazine from aqueous solution by Fenton's reagent oxidation was investigated. 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.

AB - Advanced oxidation of amoxicillin was realized in aqueous solution by using Fenton's reagent treatment. 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.

AB - The use of Fenton's reagents in destruction of waste material present in Tambla Tributory (Durgapur,India) industrial wastewater has been investigated. 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.

AB - The protection and conservation of natural resources is one of the main priorities of modern society. 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.

AB - The performance of combined Fenton oxidation and membrane bioreactor (MBR) process for the advanced treatment of an effluent from an integrated dyeing wastewater treatment plant was evaluated. 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). The final effluent of MBR can meet the reuse criteria of urban recycling water - water quality standard for miscellaneous water consumption GBT18920-2002.

AB - A central composite factorial design methodology was employed to optimise the amoxicillin degradation using the Fenton's oxidation treatment. 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.

AB - Industrial and remedial processes produce wastewater containing chelated heavy metal. 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.

AB - The removal of organic matter (TOC and COD) from a cosmetic wastewater by Fenton oxidation treatment has been evaluated. 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.

AB - The effectiveness of Fenton process in municipal landfill leachate treatment, as a pre- or post-treatment approach, has been demonstrated. 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.

AB - The central composite design (CCD) technique was used to study the effect of the Fenton's peroxidation on the removal of organic pollutants from olive oil mill wastewater (OMW). 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.

AB - Industrial wastewater typically contains various metal ions. 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.

AB - The recycling of domestic wastewater is an effective means of coping with the water shortage in Tunisia. 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.

AB - Phenol oxidation by Fenton's reagent (H2O2 + Fe2+) in aqueous solution has been studied in depth for the purpose of learning more about the reactions involved and the extent of the oxidation process, under various operating conditions. 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.

AB - Various chemical wet oxidation techniques to remove toxic non-biodegradable pollutants from wastewater were compared in this work. 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.

AB - In this study, Reactive Black 5 (RB5) was removed from synthetic wastewater using Fenton’s oxidation (FO) process. 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.

AB - Nowadays there is a continuously increasing worldwide concern for development of alternative water reuse technologies, mainly focused on agriculture and industry. 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.

AB - The technological and economic aspects of using the Fenton process to treat industrial wastewater containing morpholyne and diethylethanolamine, as well as sodium salts of naphthalene sulfonic acid and of ethylenediaminetetraacetic acid based on data obtained in pilot tests are discussed. 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.

AB - Decolourisation of wastewater using Fenton (Fe2+/H2O2) and Fenton-like (Fe3+/H2O2) reactions was investigated and compared to that of a typical azo dye, C.I. 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.

AB - The decomposition of polycyclic aromatic hydrocarbons in a creosote oily solution and in synthetic solutions containing naphthalene and pyrene was investigated in the presence of an amphoteric surfactant using electrooxidation by comparison to Fenton oxidation process. Electrolysis was carried out using a parallelepipedic electrolytic 1.5-L cell containing five anodes (expanded titanium covered with ruthenium) and five cathodes (stainless steel) alternated in the electrode pack, whereas Fenton oxidation process was carried out in 500 mL Erlenmeyer glass-flasks in which H2O2 and Fe2+ were added. Using electrochemical oxidation, the sum concentration of 16 polycyclic aromatic hydrocarbons investigated could be optimally diminished by up to 80–82% by applying a current density of 9.23 mA cm−2 and a pH of 4.0 or 7.0 for 90-min reaction period. By comparison, the best yield (46%) of Fenton oxidation process for polycyclic aromatic hydrocarbons degradation was recorded by using H2O2/Fe2+ molar ratio of 11.0 and a pH of 4.0.

AB - The study was undertaken to compare from technical and economic point of view the treatment of antibiotic aqueous solution containing amoxicillin, ampicillin, and cloxacillin by Fenton, photo-Fenton, TiO2 photocatalytic and UV/ZnO processes. 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.

AB - In this paper, a comparison of various advanced oxidation processes (O3, O3/UV, H2O2/UV, O3/H2O2/UV, Fe2+/H2O2) and chemical treatment methods using Al2(SO4)3 · 18H2O, FeCl3 and FeSO4 for the chemical oxygen demand (COD) and color removal from a polyester and acetate fiber dyeing effluent is undertaken. Advanced oxidation processes (AOPs) showed a superior performance compared to conventional chemical treatment, which maximum achievable color and COD removal for the textile effluent used in this study was 50% and 60%, respectively. Although O3/H2O2/UV combination among other AOPs methods studied in this paper was found to give the best result (99% removal for COD and 96% removal for color), use of Fe2+/H2O2 seems to show a satisfactory COD and color removal performance and to be economically more viable choice for the acetate and polyester fiber dyeing effluent on the basis of 90% removal.

AB - Soil contamination by persistent organic pollutants (POPs) is a problem faced in many countries as a result of rapid industrialisation. The suitability of Fenton oxidation for degradation of recalcitrant POPs as a short-term remediation approach has led to intense research within the field over the last few decades. 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.

AB - The oxidative decolorization of Reactive Black 5 (RB5) in aqueous solution has been studied using Fenton (H2O2/Fe2+) and photo-Fenton (H2O2/Fe2+/UV) processes. 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.

AB - Background Olive mill wastewater (OMW) generated by the olive oil extracting industry is a major pollutant, because of its high organic load and phytotoxic and antibacterial phenolic compounds which resist biological degradation. 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.

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.

AB - Abstract For 50 years, farmers around the world have relied on the herbicide atrazine—one of the triazine family of herbicides—to fight weeds in corn, grain sorghum, sugar cane, and other crops. 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. Graphical abstract

AB - This article presents an overview with critical analysis of technical applicability of advanced oxidation process (AOP) in removing chelating agents from aqueous solution. 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.

AB - Waste effluents from textile industries are a major source of water pollution. 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.

AB - Alkanolamines in the wastewater from gas treating plants are not readily biodegradable. 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.

AB - The degradation of organic matter present in olive-oil mill wastewater from two-phase olive-oil extraction process was carried out by chemical oxidation reaction. 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.

AB - Background, aim, and scope The optimal conditions of o-toluidine degradation by fluidized-bed Fenton process were determined using Box–Behnken designs (BBD). 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.

AB - The potential of the Fenton’s reagent for oxidation of p-aminophenols, which are the main developers used in white and black processes, was assessed. 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.

AB - Propylene glycol (PG) wastewater seriously threatens aquatic lives and causes health damage to human beings. 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.

AB - The degradation of salicylic acid (SA) was carried out utilizing classical Fenton reagents and modified Fenton with ferric iron salt and goethite as source of iron catalyst. 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.

AB - The present study was used to probe the treatment of simulated wastewater containing cresols by Fenton process. 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.

AB - This work studied the destruction of various M–EDTA complexes and trace organic pollutants in treated reusable wastewater under advanced oxidation using UV irradiation and ozonation. Effect of dosage of hydrogen peroxide and acidity of reaction matrices on oxidation efficiencies were investigated. The rate constant of mineralization presents a decreasing trend as Fe(III)–EDTA > Fe(II)–EDTA > Al(III)–EDTA > Pb(II)–EDTA > Na(I)–EDTA > Zn(II)–EDTA > Cu(II)–EDTA. 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. When 150 mg l−1 of H2O2 was added in the effluents, the mineralization markedly increased to 80%, 92% and 89%, respectively.

AB - The examination of the effectiveness of the chemical oxidation using Fenton's reagent (H2O2/Fe2+) for the reduction of the organic content of wastewater generated from a textile industry has been studied. 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.

AB - The study evaluated the effect of Fenton's oxidation on the particle size distribution (PSD) of significant parameters reflecting the organic carbon content of olive oil mill wastewater (OMW). 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.

AB - In this study, the electro-Fenton and fluidized-bed Fenton processes under the given conditions were used to oxidize aniline. 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.

Operating variables, such as the pH, concentrations of H2O2 and Fe2+, are used to explore the respective effects on the oxidation and decolorization of the textile wastewater. 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%.

AB - Recently more attention has been paid to emerging pollutants in water. 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.

AB - The mineralization and biodegradability increase and their combination of two traditional and two relatively new organic contaminants by Fenton reagents with three different types of iron, Fe2+, Fe3+, and Fe0 were investigated. 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.

AB - This study presents the efficiency of Fenton process in the degradation of organic compounds of nuclear laundry water. 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.

AB - The purpose of this study is to efficiently operate Fenton’s oxidation process with quantitative analysis of the amount of the organic substances removed by oxidation and coagulation in treatment of the non-biodegradable landfill leachate by Fenton’s reagents. 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.

AB - A study has been conducted to enhance degradation of a mixture of polycyclic aromatic hydrocarbons (PAHs) by combining biodegradation with hydrogen peroxide oxidation in a former manufactured gas plant (MGP) soil. 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.

AB - Chemical oxidation technologies are often employed for the treatment of complex industrial effluents that are not amenable to conventional biological methods. 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. Copyright © 2004 Society of Chemical Industry

AB - The experimental design methodology was applied having in mind the optimization of the azo dye Orange II degradation using the Fenton's reagent (mixture of H2O2 and Fe2+). 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.

AB - Advanced oxidation technologies (AOTs) have been widely investigated for their potential application in post-tertiary sewage treatment due to their ease of operation, high efficiency in organic mineralisation, inactivation of pathogens and low formation of disinfection by-products. 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.

AB - Both Fenton oxidation and the combination of aerobic Sequencing Batch Reactor (SBR) + Fenton oxidation were investigated in a bench-scale study to degrade and reuse a real textile wastewater with a TOC = 465 mg L− 1 C, COD = 2100 mg L− 1 O2 and Escherichia coli = 80,000 CFU mL− 1, according to RD 1620/2007 (Spanish Normative for wastewater reclamation and reuse). 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.

AB - The simultaneous use of Fenton reagent and irradiation for the treatment of textile wastewaters generated during a hydrogen peroxide bleaching process is investigated. 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.

AB - In the present work, the possibility of using chemical oxidation through Fenton's reagent for the pre-treatment of cork cooking wastewaters was exploited. 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).

AB - The Fenton oxidation process was applied as a pretreatment process to degrade non-biodegradable organic matters in pigment wastewater. 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.

AB - Treatment of simulated desizing wastewater by the Fenton process along with chemical coagulation was investigated. 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.

AB - Remediation of industrial wastewaters represents a stringent problem in modern society, which requires particular understanding and ad hoc solutions. 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.

AB - The addition of solid particles, namely synthetic zeolites NH4ZSM5 and HY, was investigated in order to enhance the efficiency of AOPs for dye wastewater treatment. 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.

AB - Due to stringent discharge limits, various pollutants (xenobiotics, biorecalcitrants, persistent) need to be handled carefully. 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.

AB - The use of the Fenton’s reagent (FR) (a mixture of H2O2 and Fe2+) for the kinetic determination of individual chemical species is proposed. 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.

AB - The oxidation of protocatechuic acid (PA), a typical phenol-type compound present in food processing wastewater, has been carried out by means of Fenton's reagent. 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. Keywords: Fenton's reagent; protocatechuic acid; kinetics; phenolic compounds; water treatment; hydrogen peroxide.

AB - A mixture of six phenolic acids, corresponding to an initial TOC of 370 mgC/L, was studied by Fenton's peroxidation aiming to improve the biodegradability of agro-industrial wastewaters. 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.

AB - The aim of our work was to compare Fenton's oxidation with existing biological SBR (sequencing batch reactor) reactor employed for treatment of the leachate, generated in local municipal landfill (35,000 inhabitants). 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.

AB - Three multiple input and multiple output-type fuzzy-logic-based models were developed as an artificial intelligence-based approach to model a novel integrated process (UF–IER–EDBM–FO) consisted of ultrafiltration (UF), ion exchange resins (IER), electrodialysis with bipolar membrane (EDBM), and Fenton’s oxidation (FO) units treating young, middle-aged, and stabilized landfill leachates. 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.

AB - With acrylic acid (AA) and allylthiourea (AT) as the monomers, an “instantaneous” granular hydrogel was prepared using Fenton reagent as redox initiator under an ambient temperature in air atmosphere, and then characterized by means of Fourier transform infrared spectroscopy and scanning electron microscope. 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.

AB - Background, aim, scope Treatment of wastewater has become significant with the declining water resources. 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.

AB - An experiment was conducted in a batch reactor for a real printing and dyeing wastewater pretreatment using Fenton process in this study. 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.

AB - The effectiveness of the Fenton's reagent (H2O2/Fe2+) in the treatment of carpet dyeing wastewater was investigated under different operational conditions, namely, H2O2 and FeSO4 concentrations, initial pH and temperature. 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.

AB - The applicability of Fenton's oxidation as an advanced treatment for chemical oxygen demand (COD) and color removal from anaerobically treated poultry manure wastewater was investigated. 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.

AB - A combination of hydrodynamic cavitation and heterogeneous advanced Fenton process (AFP) based on the use of zero valent iron as the catalyst has been investigated for the treatment of real industrial wastewater. 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.

AB - This study evaluated the effectiveness of Fenton's technique for the treatment of semi-aerobic landfill leachate collected from Pulau Burung Landfill Site (PBLS), Penang, Malaysia. 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.
