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 RuO

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 whereas 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
electrooxidation is an effective technique for the treatment of dyebath
effluent.
