Residual dye in hydrolyzed form is the major organic constituent present in dyebath effluent resulting in the scarcity of water resources. The objective of this study is to remove organic pollutants by electrooxidation using graphite and RuO2/IrO2/TaO2 coated titanium (MMO) as electrodes. Among the two electrode materials used, graphite was found to be better in terms of COD removal, current efficiency and energy consumption. Nearly 85% of COD was removed using graphite where as only 40 % COD removal was achieved using MMO material as electrode. The influence of chloride ion and current density on the degradation of organics was studied. The results indicate that the electro oxidation is an effective technique for the treatment of dyebath effluent.
