Fenton 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...
متن کاملOxidation of TNT by photo-Fenton process.
A series of photo-Fenton reactions have been performed for the degradation of 2,4,6-trinitrotoluene (TNT) in a 4.2-l reactor. The degradation reaction rate of TNT followed a pseudo-first-order behavior; and the rate constants for 2.4mW cm(-2)UV only, 2.4mW cm(-2)UV/H(2)O(2), Fenton, photo-Fenton (2.4mW cm(-2)) and photo-Fenton (4.7mW cm(-2)) were 0.002min(-1), 0.007min(-1), 0.014min(-1), 0.025m...
متن کاملefficacy of fered-fenton advanced oxidation process for organic loading (cod) removal from saline tannery wastewater
the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...
متن کاملOptimization of organic compounds removal from Wastewater by Electrocoagulation
Introduction: As the most hazardous sewage, hospital wastewater contains various contaminants, and its uncontrolled discharge can seriously damage the environment. Bandar Abbas is located in an arid and semi-arid region therefore, hospital wastewater should be treated through an appropriate and economic method. This study aimed to determine the efficiency of electrocoagulation with aluminum and...
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...
