Fenton and solar photo-Fenton processes for the removal of chlorpyrifos insecticide in wastewater

Fenton 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...

Photo-fenton, Coupled Biological-photo-fenton and Reverse Osmosis Processes for Textile Wastewater Reclamation: Feasibility of Use in Dyeing Processes

Sunlight-Assisted Photo-Fenton Process for Removal of Insecticide from Agricultural Wastewater

Pesticides and insecticides are harmful and toxic organic chemicals that are used for controlling pests and insects in agriculture, thereby considered as necessary evil. Agricultural wastewater, contaminated with such toxic pesticides, pollutes surface and groundwater. Pesticides are able to reach surface waters either directly or indirectly via the discharge of agricultural drainage water from...

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...

Applicability 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...
