This study aimed to utilize Palm Oil Mill Effluent (POME) and preheated Empty Fruit Bunches (EFB) as a source for enhanced biogas production in Expanded Granular Sludge Bed (EGSB) Reactor. The reactor was operated continuously for 48 days with 2 days Hydraulic Retention Time (HRT), POME : EFB mixing ratios of 1 : 0 ; 0.10 ; 0.15 ; 0.20 ; operating temperature of 35 ± 20C and 55 ± 20C. The best improved was achieved from co-digestion of POME with EFB at a mesophilic temperature of 35 ± 20C and mixing ratios of 1: 0.10, highest total biogas volume achieved was 7,400 ml (0.1359 – 0.1619 m3 CH4/kg Chemical Oxygen Demand (COD) removed), Volatile Fatty Acid (VFA)/Total Alkalinity (TA) ratios 0.1418 – 0.1582, and COD removal 61.97 – 78.87 %. The methane content was 46.10 %. Under a thermophilic temperature of 55 ± 20C and mixing ratios of 1 : 0,10, the highest total biogas volume achieved was 1.350 ml (0.0859 – 0.1358 m3 CH4/kg COD removed) VFA/TA ratios increased to 0.4498 – 0.6685 with COD removal 61.97 – 74.65 %.

Key words: biogas, POME, EFB, co-digestion, expanded granular sludge bed.
