On of the most promising technologies in the disposal of agro-industrial organic wastes is biodegradation under anaerobic circumstances. The major, profitable product of anaerobic degradation is biogas, from the environmental aspect a renewable resource. To enhance biogas production and produce a methane-rich final product an integrated anaerobic membrane bioreactor filled with moving biofilm carriers was designed. In this study, the intensification of anaerobic fermenter was investigated by using polyvinyl-alcohol (PVA) gel beads as biofilm carriers. The solid retention time can be increased by attaching microorganisms to PVA-gel beads and as a result the efficiency of biogas production can be improved. Two laboratory-scale anaerobic fermenters were run in parallel, one with biofilm carriers and one without. The results showed that, compared to the control system, in the carrier-filled fermenter the efficiency of biogas production was enhanced by 28% as a result of the biofilm formation on the surface of the carriers. In addition, the COD concentration of the effluent was decreased by 80-88%, 10% more than in the control reactor.
