COD REMOVAL FROM MUNICIPAL WASTEWATER USING ELECTROCOAGULATION BY DIFFERENT AL/FE ELECTRODES

In the present study different combinations of Al and Fe electrodes are used for improving treatment efficiency in electrocoagulation (EC) process to purify domestic wastewater. Various factors be studied assessment COD removal form pH (3–9), time (10–60 min), density current (9.0–40 A/m2). Depending on influencing factor Al–Al Fe–Fe able minimize percentage up 85.0 % 90% respectively. Similarly 86.0 87.50 were removed, when aluminium iron combined as Al–Fe Fe–Al Further, operating parameters investigated COD. The reported that, combination affects greatly using EC technique.
