Removal of Basic Dyes from Textile Wastewater by Applying Advanced Oxidation Process Using Fenton Reagents (original) (raw)

In this study Advanced oxidation process using Fenton reagents is considered for the application of textile dye-house wastewater treatment. A representative basic dye-house wastewater sample has been brought from K.K. Textile Factory and its characteristic is analyzed and the result shows that dye-house wastewaters, containing basic dyes, are hazardous to the environment since their COD & BOD values are higher than the free discharge limit values and also they are highly colored even at the lower dye concentration operation cases. After characterizing the wastewater, advanced oxidation of a Basic Blue 41 dyes using solar -Fenton treatment was investigated in batch experiments using Box–Behnken statistical experiment design and the response surface analysis. Dyestuff, H2O2 and Fe2+ concentrations were selected as independent variables in Box– Behnken design while color and COD removal were considered as the response functions. Color removal increased with increasing H2O2 and Fe2+ con...
