palm oil mill effluent ponding system

Comparing the pollution load of the palm oil mill industry with domestic sewage, in average, the water pollution of the total palm oil mill industry is equal to the wastewater generated by around 3 million people per day - in terms of BOD 5 (Annex A2 and map). Both empirical and rational design models were presented. Some first order kinetic coefficients were calculated for rubber mill effluents based on data for existing ponding systems. These constants ranged from 0,065 to 0.27 day1. In general, there are four types of treatment systems adopted by the palm oil industry, Pool sewage treatment system is the most used and effective treatment. The waste water has high organic matter content, biochemical oxygen demand BOD is about 25000ppm, required by qualified deal before emissions. panied by the generation of effluent. This polluting effluent with its high content of chemical oxygen demand (COD), 50,000 mg/L, biological oxygen demand (BOD), 30,000 mg/L, oil and Adoption of such models were deemed closest to a way of designing ponds. Most palm oil mills in Malaysia have adopted the ponding system for the treatment of POME [ 20 ]. The coefficient for a pond exhibiting plug flow was found to be 0.068 day~x. Kinetic coefficients for palm oil mill effluent for both completely mixed and plug flow systems were also presented. The Malaysian experience in effluent control in the palm oil industry due to the opening of the factory vastly. Ponding is proposed as a viable low-cost treatment method for .palm oil and rubber mill effluents. −Typical palm oil mill process and POME generation points Separator sludge Crude palm oil Clarification Drying Digester and pressing Thresher Sterilizer (Direct injection) Fresh fruit bunches Sludge pit Sterilizer condensate Hydrocyclonewashwater Treated effluent Open ponding Mill boiler Fresh water Motive steam, 3 barg Applications of ponding systems for palm oil mill effluent, rubber effluent and domestic sewage in Malaysia were discussed. It is about 85 % of palm oil mills in Malaysia had taken this method as their way to treat the POME. This palm oil mill effluent treatment system is cost-effective, only needs adequate space, less investment costs. Palm oil mill effluent (POME) contains a high concentration of organic matter. aquatic life. The reason of using ponding system is due to its cost that is low cost in term of labour compared to other treatment method [5]. Palm oil mill effluent (POME) is a po-tential environmental pollutant. Insufficient data prevented the derivation of kinetic constants for domestic sewage oxidation ponds. Theoretical considerations were reviewed and discussed in relation to the design of ponds. The term oxidation pond has also been loosely used and can mean aerobic, facultative, maturation, or sometimes it may even be used for anaerobic pond. These constants ranged from 0,065 to 0.27 day1. (Palm Oil Mill Effluent Treatment, 2015) Ponding is a general term which includes waste stabilization lagoons (ponds) and oxidation ponds. The most common method in treating Palm oil mill effluent (POME) is using a conventional ponding method. Currently, some 85% of POME treat-ment of more than 400 mills in the country is based on open ponding system, which involves biologi- On average, 1.5 m3 water is needed to pro-cess 1 t of fresh fruit bunches and half of this ends up as POME. The current POME treatment trend is now gearing toward biogas capture technology and integrated POME treatment system with the ultimate aim of achieving zero discharge concept in the palm oil mill.
