Palm Oil Mill Effluent Pome Treatment System

It was estimated that a processing plant with a capacity of 10 tons fresh fruit per hour would need a water treatment plant comparable to that required by a population of half a million inhabitants brezing 1986.

Palm oil mill effluent pome treatment system. The application of membrane separation technology coupled with adsorption treatment pre treatment can be effective means of treating palm oil mill effluent pome the pre treatment process was done by stirring the raw palm oil mill effluent pome with 0 20 g l of palm kernel shell based activated carbon pks ac in 35 94 min with stirring speed 39 82 rpm and able to reduce 71 26 of suspended solid. Wong and springer 1980. Hybrid treatment of palm oil mill effluent pome treatment was performed. Large volumes of untreated palm oil mill effluent pome pose threat to aquatic environment due to the presence of very high organic content.

Pome is the main cause of environmental pollution due to its high acidity high biological oxygen demand bod and chemical oxygen demand cod. Palm oil mill effluent is a thick brownish liquid that contains high solids oil and grease cod and bod values. Waste stabilization ponds activated sludge system closed anaerobic digester and land application system. Several treatment technologies have been used for pome treatment since the direct.

Some of the palm oil mills have adopted open tank digester and extended aeration systems in pome treatment. 3 atmospheric methane concentrations incredibly increased by 30 in. Introduction palm oil mill effluent pome is a viscous brown liquid with fine suspended solids at ph between 4 and 5 1 and a highly polluting wastewater that directly and indirectly contaminates the environment. Stepwise feeding of pome at 0 2 m3 day 1resulted in 80 removal of contaminant.

Palm oil mill effluent is a highly polluting material due to its high biological oxygen demand bod low ph and colloidal nature. Anaerobic aerobic wetland sequential system and drum drying treatment is proposed. In domestic sewage wastewater treatment there is ponding activated sludge extended aeration and diffused air in use in malaysia asairinachan 1979. Anaerobic ponds arc usually the first stage in the treatment of pome.

After 360 days the organic removals have sustained demonstrating the plant s fitness. In general there are four types of treatment systems adopted by the palm oil industry which are as follows. 2 the chemical properties of pome vary widely throughout the year because of mill operations and seasonal cropping.
