Palm Oil Mill Effluent (POME) Treatment by Using An Electrocoagulation Method

Electro-coagulation (EC) is an electrochemical technique which has been employed in the treatment of various kind of wastewater. In this study, the potential use of EC for the treatment of POME was investigated This study evaluates the removal of COD, AN, SS and Color as parameters. Al and Fe. electrodes were connected to the positive and negative pole of DC power supply. The amount of COD, AN, SS and color was measured at initial pH and in electric potential of 10, 15, 20, 25 and 30 volts. The experiment was started up for 30 minutes running tune and 30 minutes of retention time after the experiment finish. Results show that both plates show a good potential in removing parameters. Al plates show an impressive potential when removing COD, AN, SS and Color, 51.7%, 78.7%, 82.9% and 76.4% respectively at 25V, while Fe plates at 20V electric potential show 62.4%, 73%, 93.5% and 64.1% removal efficiencies respectively to COD, AN, SS and Color. In the effect of distances, Al removed 82.6%, 83%, 85.3% and 90.7% of COD, AN, SS and Color in 5 cm distance between electrode, while Fe electrode shows 84.5%, 92%, 95.2% and 75.4% removal efficiencies in 10 cm distance between electrodes.
