ELEKTROKOAGULASI LIMBAH CAIR KELAPA SAWIT VARIASI KUAT ARUS, LAMA WAKTU DAN JARAK ELEKTRODA

Abstract

Electrocoagulation is one method that can be used in the processing of palm oil effluent. The electrocoagulation method is one of the renewable methods in treating waste. Waste treatment by electrocoagulation is more efficient than other methods. This electrocoagulation research uses variations in current strength, electrode distance and electrocoagulation time to reduce the COD value of palm oil effluent. Based on the results of the study, the 2 ampere test sample had a COD value of 332.02 mg/L with a COD reduction of 70.48%. The 0.5 cm electrode distance test sample had a COD value of 281.95 mg/L with a COD reduction of 74.93%. The test sample for 240 minutes of electrocoagulation had a COD value of 116.79 mg/L with a COD reduction of 89.62%. The electrocoagulation process with a constant time of 120 minutes can reduce COD up to 74.93%. The use of electrocoagulation time of 240 minutes can reduce COD up to 89.62%.
