Two-stage anaerobic process coupled with single-stage aerobic process for raw palm oil mill effluent treatment

Malaysia is the second large contributor in the palm oil industry after Indonesia. Yearly, approximately 13 million tonnes of crude palm oil are produced. During the crude palm oil extraction process, huge amount of brownish-oily liquid sludge, known as palm oil mill effluent (POME), are generated....

Yearly, approximately 13 million tonnes of crude palm oil are produced. During the crude palm oil extraction process, huge amount of brownish-oily liquid sludge, known as palm oil mill effluent (POME), are generated.

Therefore, this study aimed to employ the principle of two-stage anaerobic process followed by a single stage aerobic process for the treatment of fresh raw POME. The treatment efficiency of this system was examined by evaluating the removal of several important parameters, namely chemical oxygen demand (COD) and sludge reduction reported in terms of total suspended solids.
