Naval derusting wastewater containing high concentration of iron, treated in UV photo-Fenton-like oxidation.
The UV photooxidation with Fe(III) and H2O2 was employed to treat a naval derusting wastewater, which contains the high COD (chemical oxygen demand) and various metal concentrations exceptionally with high concentrations of citric acid and iron. Because of its iron containment, the Fenton-like reaction automatically took place with the added amount of H2O2. The decomposition rate was found in a...
متن کاملTreatment of saline wastewater contaminated with hydrocarbons by the photo-Fenton process.
The application of the photo-Fenton process to the treatment of saline wastewater contaminated with hydrocarbons is investigated. Aqueous saline solutions containing raw gasoline were used as a model oil-field-produced water. The dependence on concentrations of the following reagents has been appropriately evaluated: hydrogen peroxide (100-200 mM), iron ions (0.5-1 mM), and sodium chloride (200...
متن کاملApplicability of Fenton and photo-Fenton Processes to Combined Industrial and Domestic Wastewater
The applicability of Fenton and photo-Fenton processes as a pretreatment stage to combined wastewater was investigated. The wastewater was obtained from the inlet of the aeration tank in 42 Evler industrial and domestic wastewater treatment plant. The effects of different process variables such as initial Fe2 (c0 8 33 mmol L –1) and H2O2 (c0 65 165 mmol L –1) concentrations, pH (3 7.75) and rea...
متن کاملFenton and solar photo-Fenton processes for the removal of chlorpyrifos insecticide in wastewater
The degradation of chlorpyrifos in water by Fenton (H2O2/Fe 2+) and solar photo-Fenton (H2O2/Fe 2+/solar light) processes was investigated. A laboratory-scale reactor was designed to evaluate and select the optimal oxidation condition. The degradation rate is strongly dependent on pH, temperature, H2O2 dosing rate, and initial concentrations of the insecticide and Fe 2+. The kinetics of organic...
متن کاملFenton and Solar Photo-fenton Oxidation of Industrial Wastewater Containing Pesticides
Assessment the efficiency of Fenton process (Fe 2+ /H2O2), versus photo-Fenton reaction (TiO2/Fe 2+ /H2O2/UV) for removal of Chloropyrifos, and COD from pesticide wastewater were investigated. Solar compound parabolic collectors (CPC) pilot scale with borosilicate tubes was used for photo-Fenton process. The effect of reaction time, initial pH and dosage of H2O2, FeSO4, TiO2 were studied for bo...
