Description Treatment of composite wastewater generating from the industrial estates is a great challenge. The
present study examines the applicability of aerated electrocoagulation and modified peroxi-coagulation
processes for removing color and COD from composite wastewater. Iron plates were used as anodes and
cathodes in both electrochemical processes and experiments were carried out in a working volume of 2 L.
Aeration enhanced the efficiency of electrocoagulation process significantly. More than 50% of COD and
60% of color were removed after 1 h of electrocoagulation process operated at pH 3 and applied voltage
of 1 V. Efficiency of the modified peroxi-coagulation process was significantly higher than that of aerated
electrocoagulation. COD and color removal efficiencies of the modified peroxi-coagulation process were
found as 77.7% and 97%, respectively after 1 h of electrolysis operated at 1 V, solution pH 3 and 50 mM
hydrogen peroxide addition. This improved efficiency of modified peroxi-coagulation compared to
aerated electrocoagulation is mainly due to the attack of in-situ generated hydroxyl radicals
