Outline of Final Research Achievements

Effects of microwave pretreatment of dewatered sludge on anaerobic digestion was examined. Although biogas production potential of dewatered sludge from an oxidation process was low, that increased by 80% by microwave pretreatment. Effects of microwave was estimated to be both heat solubilization of EPS and improve of biodegradability of suspended organic matter. As a result of a continuous digestion experiment, it was demonstrated that gas yield improved by microwave pretreatment.
