Abstract

The study was carried out on dye wastewater treated by AOPs (advanced oxidation process) for the removal of
residual COD on a laboratory scale. This study compares the treatment efficiency of COD removal by Fenton’s treatment
& combined Fenton & Ultrasonic cavitation performed at the same time interval. Raw wastewater showed COD around
2800 – 2900 mg/l. The effect of different parameters & dosage combinations such as pH, COD/ H2O2 & H2O2/Fe+2 were
analyzed. About 81% reduction in COD is observed at pH 3, COD: H2O2 as 2:1 and H2O2: Fe+2
as 10:1 by Fenton’s
treatment & 88% by combined Fenton & Sonolysis treatment. Hence, it is suggested that combined Fenton & Ultrasonic
cavitation proves to be more efficient treatment for COD reduction and thereby improving biodegradability of the
wastewater.
