Adoption of such models were deemed closest to a way of designing ponds. Some first order kinetic coefficients were calculated for rubber mill effluents based on data for existing ponding systems. Theoretical considerations were reviewed and discussed in relation to the design of ponds. 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]. 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. Kinetic coefficients for palm oil mill Applications of ponding systems for palm oil mill effluent, rubber effluent and domestic sewage in Malaysia were discussed. Both empirical and rational design models were presented. 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. 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. It is about 85 % of palm oil mills in Malaysia had taken this method as their way to treat the POME. panied by the generation of effluent. Currently, some 85% of POME treat-ment of more than 400 mills in the country is based on open ponding system, which involves biologi- 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. (Palm Oil Mill Effluent Treatment, 2015) Ponding is a general term which includes waste stabilization lagoons (ponds) and oxidation ponds. These constants ranged from 0,065 to 0.27 day1. The Malaysian experience in effluent control in the palm oil industry due to the opening of the factory vastly. 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. These constants ranged from 0,065 to 0.27 day1. aquatic life. Most palm oil mills in Malaysia have adopted the ponding system for the treatment of POME [ 20 ]. Ponding is proposed as a viable low-cost treatment method for .palm oil and rubber mill effluents. The most common method in treating Palm oil mill effluent (POME) is using a conventional ponding method. 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). −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 Insufficient data prevented the derivation of kinetic constants for domestic sewage oxidation ponds. 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.
