- Characteristics of palm oil mill liquid waste of effluent RANUT (Reactor Anaerobic Fixed bed) was not meet yet the basic quality requirement of liquid waste for TSS (Total Suspended Solid) and COD (Chemical Oxygen Demand).. Therefore it requires further treatment to reduce pollutants contained, so its characteristics can meet the quality standard. In this research, electrocoagulation is used as a technique to treat the waste. The research was carried out by using the factorial design with three factors, those are kind of electrode material, voltage, and distance of electrode. Type of electrode material used is aluminium, zink and iron. Voltage variation are 11, 12 and 13 Volt, while the distances of electrode used are 1.0; 1.5 and 2.0 cm. While the constant variabels are pH 6.5, and retention time 3 hours. The treatment was operated in batch reactor with volume of 2000 mL. The Responses would be observed are changes of pH, removal percentage of turbidity, color, TSS, and COD. Analysis of pH was carried out by using a pH meter SensIon156, COD by HACH Method 8000, TSS was according to SNI 06-2413-1991, the color by method 8025, and turbidity by Nephelometric method. Research results found that electrocoagulation could increase the price of waste pH. Best pH is 7-8 which was obtained by using aluminium electrode. Highest percentage of pollutant removal is obtained by using aluminium electrode at voltage 12 Volt and distance of electrode 1.5 cm, with their exclusion percentage of turbidity is 98.40%, color is 97.55%, TSS is 95.30% and COD is 93.46%. It was known that the value of TSS and COD were under the basic quality requirement of palm oil mill liquid waste. The results also showed that the influence of each factors and the influence of interactions between factors on the responses is significant.
