Fenton Oxidation Process

Fenton pretreatment has been used for treating dye wastewater. The effects of the dos of H2O2 and FeSO4, reaction time and pH on the removal COD were investigated. It was found that, when the reaction conditions are as follows: COD 2850 mg/L dyeing wastewater, the dosage of H2O2 is 140mmol/L, FeSO4 17.02 mmol/L, pH 7.6, and reaction time 1.0 h, the CODcr of dye wastewater removal rate of up to 70%. Fenton pretreatment process of dye wastewater has a broad prospect.

The worldwide population is developing and along these lines, the world may event incredible freshwater shortage. Our water assets are lacking and, thus, water management and reusing techniques are the main choices for receiving freshwater later on decades. Accordingly, there is an incredible requirement for the advancement of proper, reasonable and quick wastewater. The common plan of this investigation is based on assessment and comparison, of the chance of apply advanced treatment techniques (Aeration process and Fenton oxidation process) for the exclusion of residuals organic pollutant present in Dye wastewater. The various procedures, which influence the compound oxidation, for colors in their fluid arrangements are considered by utilizing Aeration and Fenton's responses. These Processes are Aeration and Fenton Oxidation Process- (Hydrogen peroxide dose). Finally, EC, COD, BOD, Turbidity, TDS, TSS, and Phosphate, when the oxidation procedure is determined to guarantee the flawless obliteration of natural colors during their expulsion from wastewater. The Compared optimum conditions were 6ml/l of Fenton (H2O2) demonstrate that Fenton's oxidation procedure effectively accomplished excellent evacuation capability.

AbstractAdvanced oxidation of an azo dye, Basic Blue 9 (BB9) by Fenton oxidation was investigated in batch experiments. The UV-vis spectral changes of in aqueous solution during Fenton process were studied. It was easier to destruct the azo linkage group than to destruct the aromatic rings of (BB9) by Fenton process. The effects of different reaction parameters such as initial ferrous concentration, initial hydrogen peroxide (H
