چکیده
Palm oil processing operation is invariably accompanied by palm oil mill effluent (POME) considered to be an environmental pollutant. While anaerobic digestion and the present tertiary treatment technologies of POME are able to meet the current regulatory effluent discharge requirement of biological oxygen demand (BOD) 100 mg litre – the current limit set by the Department of Environment (DOE) – the existing technologies are unable to consistently meet the proposed stringent BOD regulatory requirement of 20 mg litre to be imposed by the DOE. This article investigates the possibility of integrating several bioprocesses for POME treatment at the Malaysian palm oil mills by transforming the POME into several high valueadded products; with BOD 20 mg litre attainable at its final discharge. This integrated approach has the potential of achieving zero-effluent discharge along with the production of biogas, biofertiliser and recycled water, in treating industrial wastewater to reduce pollution.

The Performance Evaluation of Anaerobic Methods for Palm Oil Mill Effluent (POME) Treatment: A Review
Palm oil mill effluent (POME) is an important source of inland water pollution when released into local rivers or lakes without treatment. In the process of palm oil milling, POME is generat‐ ed through sterilization of fresh oil palm fruit bunches, clarification of palm oil and effluent from hydro-cyclone operations [Borja et al.,1996a]. POME is a viscous brown liquid with fine suspended solid...

Producing crude palm oil (CPO) will have side effect on producing palm oil mill effluent (POME). Besides of high COD /BOD contents, POME still contains high amount of nutrients (nitrogen, phosphor and mineral). Traditional treatment of palm oil mill effluent using facultative anaerobic method not fully eliminated COD and BOD into allowable limit. The objective of this research was to utilize p...
