Removal of Dye from Real Textile Wastewater by Sono-Electro-Fenton Oxidation Process

Abstract

Sono-Electro Fenton processes were applied to the oxidative decolorisation of real textile wastewater in this study. The sono-electro Fenton process was performed by indirect sonication in an ultrasonic water bath, which was operated at a fixed 35-kHz frequency and 80 W powers. Electrolysis was provided by using a DC power supply. It was determined that efficiency on removing dye from real wastewater: as 97.03% for Pt-Co, 96.40% for 436 nm, 97.95% for 525 nm, 98.15% for 620 nm in RES colour removal was determined for the sono-electro fenton under the optimum conditions which are 150 µL/L H₂O₂, 0.15 A current density and at pH 2.7 respectively.
