Kaewchai, S. and Prasertsan, P. Screening and application of thermotolerant microorganisms and their flocculant for treatment of palm oil mill effluent Songklanakarin J. Sci. Technol., 2002, 24(3) : 413-420 Among fifteen thermotolerant polymer-producing isolates, three strains SM 29, WD 90, and SM 38 produced polymer posessing very high flocculating activities (24.81, 14.63 and 10.84, respectiv...

The biggest agricultural sector that contributes to the Malaysian economy is the oil palm industry. The effluent generated during the production of crude palm oil known as palm oil mill effluent (POME). POME undergoes anaerobic treatment that requires long retention time and produces large amount of methane that consequently contributes to global warming. In this study, an isolated bacteria was...

This study evaluates the physicochemical characteristics, total and available copper zinc in soils affected by four palm oil mills effluent (POME) of Oghareki Oghara Kingdom, Delta State, Nigeria using standard methods. The results showed generally increased pH, organic matter, electrical conductivity, phosphorus, exchangeable bases cation exchange capacity (CEC), compared to non-POME-contamina...

This study aimed to investigate anaerobic co-digestion of palm oil mill effluent (POME) with cassava peels (CP) and cabbage waste (CW) for biomethane production. The digestion (AD) in 10L capacity bioreactors loaded separately three different ratios (3L/ 520g, 3L/ 600g 680g) POME/CP, POME/CW POME only (control) was operated under ambient temperature (25 - 36⁰C) pH range 6.5 8.5 45 days. Standar...

An anaerobic digestion of palm oil mill effluent (POME) for production of biogas was carried out at pilot scale under thermophilic condition. The objective of this research is to maintain short hydraulic retention time (HRT) and high degradation of the POME to biogas by applying recycle sludge. Fresh POME from PTPN IV without further treatment was used as feed. The fermentation process occurred...

The principle of maximum entropy (POME) developed in communication and information sciences has recently been found to have wide ranging applications in hydrology and water resources. This paper surveys some of these applications with particular reference to (1) derivation of frequency distributions, (2) parameter estimation, (3) evaluation of data acquisition systems, (4) derivation of functio...

The discharge of palm oil mill effluent (POME) without effective treatment is highly toxic to the environment and receiving waters due its high chemical oxygen demand , biochemical increased levels suspended solids. ponding system regarded as a conventional method for POME but requires long retention time extensive areas. Other processes, such physicochemical treatment, have also been applied t...

The direct discharge of palm oil mill effluent (POME) wastewater causes serious environmental pollution due to its high chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Traditional ways for POME treatment have both economical and environmental disadvantages. In this study, a membrane anaerobic system (MAS) was used as an alternative, cost effective method for treating POME. Six...

High amount of turbidity was identified as one the important factor affecting successful cultivation microalgae in palm oil mill effluent (POME). In this study, Chlorella sorokiniana cultivated POME, under different dilutions 80, 60, 40 and 20% (v/v) with distilled water. The aim study is to investigate effect POME on specific growth rate microalgae. results found that, C. grew both sterilized ...

Palm oil industries have been contributing significantly towards the country’s economy and increase standard of living among Malaysians. However, it has also been identified as the major contributor for discharging the largest pollution load throughout the country. Owing to high biochemical oxygen demand (BOD) and chemical oxygen demand (COD), the palm oil mill effluent (POME) cannot be dischar...
