Palm oil mill effluent (POME) is one of the largest wastes produced by palm oil industries. The electrochemical process offers an alternative to treat POME with several advantages. Anodic oxidation as one of the mechanisms from the electrochemical process has high efficacy to oxidize the organic content. This oxidation ability depends on electrode materials. In this study, graphite was used as electrode materials. The effects of voltage, electrolysis time and electrolyte support was investigated. The results show the highest removal efficiency obtained were 71% of COD reduction and complete color removal at optimum condition. Using graphite as an electrode was found efficient compared to other traditional materials and capable to reduce time the POME treatment compared to conventional methods.
