 Fixed film biomethanation of distillery spentwash using low cost porous mediaR. Seth, S.K. Goyal and B.K. Handa Resources, Conservation & Recycling, 1995, vol. 14, issue 2, 79-89 Abstract: Investigations were conducted using a low cost support media for microbial attachment and growth for the anaerobic treatment of sugarcane molasses based distillery spentwash employing fixed film reactor (FFR) technology. An HRT of 3 d corresponding to an OLR of 22 kg COD m−3d−1 based on reactor liquid volume (VL) (VL = 0.534 Veb, empty bed volume) with COD reduction of 71.8% and gas yield of 0.45 m3 kg−1 COD removed has been achieved in the methane phase. Volatile solids analysis has revealed that about 75% of the biomass is attached to the inert media surface leading to a major contribution in the performance of the methane reactor. Solids retention time (SRT) of 106 d has been calculated at an HRT of 3 d, thereby demonstrating superiority of FFR technology over other conventional anaerobic treatment methods. Further, the waste treatment is affected by the entire media height due to continuous effluent recycling. Comparison with granular activated carbon (GAC) has revealed that the media used in the present study has comparable or even better performance due to larger size of the pores in the media.
