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%.
