Journal of Indian Water Works AssociationSummary: The technique of electrocoagulation (EC) is investigated with iron and aluminum electrodes. Comparative study of iron and aluminum as electrodes material on removal of COD and Color is conducted to investigate the feasibility ofmost efficient electrode material for the process. The effect of relevant operating conditions such as current density 6) and electrolysis time were investigated for evaluation of performance of the electrodes.
The result indicate that electrocoagulation technique is effective in the removal of COD and Color. Results indicate that COD removal efficiency of 95 % achieved at current density of 7.81 to 7.97 mA/cm2 at electrode spacing of 20mm at electrolysis time of 60 min with iron electrode. In case of aluminum electrodes the optimum COD removal efficiency of 91% achieved at the current density of 23.44 to 23.59 mA/cm2 at electrolysis time of 75 min at electrode spacing 20 mm.
The color removal of 100% is noticed with iron electrodes at all the current densities and all electrode spacing. However in case of aluminum electrodes the color removal efficiencies noticed in the range ofS2 to 95%. Maximum of 95 % color removal occurred with iron electrodes at current density of 23.44 to 23.59 mA/cm2 at electrode spacing of 10 mm. Iron as an electrode material is observed to be more efficient in the removal of COD and Color than aluminum. Iron is efficient in the removal of pollutants even at lower current densities.
