Abstract: Palm oil industry is one of the three major agro - industries in the South of Thailand. For every ton of palm oil produced, it generates about 0.87 ton of effluent which is very high in organic matter and causes serious problems to the natural water. A laboratory scale anaerobic treatment was used to treat palm oil mill effluent containing 58,475 mg ]-'BOD, 110,400 mg 1-' COD, 71,930 mg 1-' (PONIE) total solids, 43280 mg 1-' suspended solids and pH of 4.5. Pretreatment of POME by two thermotolerant fungal isolates revealed that the isolate ST29 cultivated under aseptic condition at 45OC and shaker speed of 200 rpm gave 61.5% COD removal and 91.4% oil & grease removal within 2 days while the isolate ST4 cultivated under septic condition gave the values of 84.2 and 62.2% respectively after 3 days incubation. The effects of hydraulic retention time (HRT), organic loading rate (OLR), COD: N ratio and temperature on the anaerobic digestion of POME were investigated. The highest COD reduction of 81.10% was achieved from the optimum conditions at 10 days HRT, OLR of 9.50 kg COD m4d-', C0D:N ratio of 65 and 50?C. Biogas production, in general, was greater than 0.30 m3/m3/d. Comparison on anaerobic treatment using POME and biopretreated POME revealed that the biopretreated POME gave higher efficiency on COD removal and biogas production
