Production of Crude Palm Oil (CPO) is increasing from year to year and is predicted to reach 41.6 million tons per year in 2018. Each ton of CPO will produce 3,28 m3 of POME during the production process. Improper handling of POME, besides causing soil pollution and flying, will release methane gas that categorized as GHG. BPPT cooperate  with PTPN V utilized POME to produce biogas and then be converted into electricity in a Biogas Power Plant (PLTBg) in Terantam with a design capacity of 700 kW. The reactor used is a closed Anaerobic Lagoon (CAL) reactor equipped with a recirculation pump. From the evaluations, the technology chosen was not optimal from the operation, its evaluaed from the accumulation of cakes and sludge collected in the reactor which could be disturb during an anaerobic reaction. The next technology development will be carried out with the development of PLTBg in Sei Pagar using CSTR technology. At the same reactor capacity, CSTR has a faster HRT compared to CAL. CSTR is also easier in control of pH and temperature, also requires less land.Keyword : POME, Biogas, CSTR, Covered Lagoon, HRT, OLR

Based on An / OSBR, the paper explores the different sludge loading and nitrate concentrations under the conditions of An / OSBR effects of biological phosphorus removal systems.The influent phosphorus concentration constant at 10 ± 0.5mg / L, in order to compare the end of the anaerobic and effluent TP concentration.The results showed that: ①With the increasing of nitrate concentrations , PAOs release phosphorus in the anaerobic reaction zone is decreased, nitrate appears to reduce the synthesis of PHB, which is due to PHB synthesis and denitrification requires a simple carbon source as hydrogen donor, resulting in competition;② With the COD sludge load increases, the effluent TP concentration decreased, when the COD sludge load ≥ 0.46mgCOD/mgMLSS · d, the effluent TP concentrations is less than 1mg / L;③ When the reaction temperature was 25 °C and 15 °C , the releasing phosphorus in anaerobic and COD sludge load have a good correlation,Linear relationship between the two were: y = 0.72 +71.91 x ( 25 °C), y = 2.81 +73.33 x (15 °C);
