This study investigated gas production from Water Hyacinth Extracted by the anaerobic process. The substrate used in this study was water hyacinth extract and microorganisms came from cow dung in a semi-continuous single-stage operation. The 5 liter bioreactors were operated. Organic Loading Rates (OLRs) were 1.63, 2.29 and 2.94 kg COD/m3-day respectively, which corresponded to hydraulic retention time (HRT) of 10, 8 and 6 days. The experiments were performed at the temperature of 30oC. The initial biomass in all reactors was approximately 41,980 mg Mixed Liquor Suspended Solids per Liter. The maximum methane yield at STP (104.50 L/kg of COD degraded or 295.42 L/kg of TVS degraded) was observed at an OLR of 1.63 kg COD/m3-day. At this OLR and HRT, the efficiency removal of COD and TVS was 89.53% and 72.49%, respectively.
