Photo-Fenton and sequencing batch reactor coupled to photo-Fenton processes for textile wastewater reclamation: Feasibility of reuse in dyeing processes

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

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...

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...

Decolourisation of textile dyeing Wastewater by modified solar Photo-Fenton Oxidation

In a laboratory study, decolourisation of real textile dyeing wastewater by modified solar photo-Fenton (Steel scrap/ H2O2 ) process under irradiation with sunlight was examined. Batch experiments were conducted to determine optimal operating conditions .The optimal doses of H2O2 and steel scrap were 15 mL/L and 1 g/L, respectively at pH 3.Colour removal of 89% was obtained under optimum condit...

Textile Dyeing Wastewater Treatment by Coupling Fenton’s Reagent and Aerobic Sequencing Batch Reactor Processes

The oxidation of organic compounds and color removal of a synthetic dyeing effluent when treated with a combination of Fenton’s Reagent and biological oxidation in a sequencing batch reactor was evaluated in this work. A central composite design approach was used to find the best conditions of temperature, hydrogen peroxide and ferrous ion concentrations that maximize color and dissolved organi...
