The Malaysian palm oil industry has been growing steadily during the past few decades establishing a prominent place in the economy of the nation. In 2014, the land under oil palm cultivation was about 5.39 million hectares in Malaysia with 443 palm oil mills in operation (MPOB Statistics, 2015). The production of crude palm oil (CPO) was 19.96 million tonnes in 2015, contributing to more than 33.15% of the world production of palm oil. However, the production of palm oil also generated a large amount of palm oil mill effluent (POME) at the average production rate of 0.67 t-1 FFB processed. Based on the crude palm oil production in 2015, the volume of POME generated was about 99.51 million tonnes. The POME originated from three sources, 1) steriliser condensate, 2) separator sludge or sludge centrifuge, and 3) hydro cyclone wastewater or clay bath used for cracked mixture separation (kernel separation).
