THE EFFECTS of PH and HYDROGEN PEROXIDE CONCENTRATION on CHEMICAL OXYGEN DEMAND (COD) and COLOR REMOVAL FROM LEACHATE by ELECTRO-FENTON METHOD

Abstract

This study investigated how COD and color removal efficiencies from leachate changed with pH (2.5-4) and H2O2 (1000-3000 mg/L) by electro-Fenton method. Maximum COD and color removals were 68% and 69%, respectively, with electrical energy consumptions of 0.79 and 0.108 kWh/m3. Since the removal efficiencies obtained could not meet the discharge limits in Turkey, it would be more appropriate to apply electro-Fenton together with other treatment methods to achieve higher COD and color removal efficiencies.
