Study on Performance of Electro-Fenton for Color Removal from Real Textile Wastewater Based on ADMI

The Electro-Fenton process with applied H2O2 and electro-generated ferrous ion was investigated for treatment of real textile wastewater. The effects of various factors such as current density, H2O2 dosage and reaction time on color and COD removal from real textile wastewater were evaluated. Likewise, the amounts of energy consumption and generation of ferrous ion were calculated. The results indicated that the application of 11.25mA/cm2 current density with 73mM H2O2 provided 67.9% decolorisation within 45min of electrolysis time. Moreover, in this condition, energy consumption was 8.37 KWh/kg of CODr. Finally, the ADMI method and maximum absorbance at wavelength of 400nm as two methods of color measurement were compared for decolorisation of real textile wastewater.
