Sago wastewater having intolerable odor with higher chemical oxygen demand (COD) leads to environmental damage. When it is treated appropriately, wastewater may possibly be utilized for irrigation and aquaculture. The present study reveals the biogas generation during the treatment of realtime sago wastewater using a laboratory-scale up-flow anaerobic sludge fixed film reactor with a working volume of 28.07 L. The reactor attained the steady-state on 14th day itself due to the combination of up-flow anaerobic sludge blanket reactor and fixed film process in a single reactor. The results indicated that the maximum biogas was attained at 0.151 m3/kg COD with the maximum COD removal efficiency being 92.076% at an organic loading rate of 0.119 kg COD/m3d with 4.5 d hydraulic retention time.
