Treatment of Leachate from Garbage using Electrocoagulation Type MP-P (MonoPolar-Paralel) Methode

Leachate water is a very dangerous liquid due to its organic and inorganic content that can pollute water body around the landfill, hence treatment is needed. Electrocoagulation is one of the methods that can be used. The research aims to determine a characteristic of leachate water at TPA Sukawinatan (COD, pH, BOD₅, TSS, and Cd content), the effect to electrodes distance (aluminium anode and iron cathode) and optimum time of treatment Leachate Water using electrocoagulation type MP-P (MonoPolar-Parallel) method. The electrical potential was set at 12 volts and time variations of 30,60,75, 90 and 120 minutes and electrodes distances of 6, 7 and 8 cm. The result obtained shown that COD decreased to 529.20 mg/L, pH became 8.34, BOD₅ decreased to 17.6 mg/L, TSS became 108 mg/L and <0.0015 mg/L of Cd content. The optimum electrodes distance to treat leachate water was found 8 cm in 120 minutes fo electrocoagulation type MP-P. (paper)
