CODIGESTION WITH GLYCEROL FOR IMPROVED BIOGAS PRODUCTION

摘要

Codigestion of organic wastes during anaerobic treatment of municipal wastewater was identified, as part of Sydney Water's Energy R&D Program, as one way in which Sydney Water can optimise solids processing and biogas production. Sydney Water aims to harness the natural anaerobic digestion process to maximise its renewable energy generation and possibly expand its services to customers beyond traditional water industry services. To quantify the potential benefits of codigestion for Sydney Water, two pilot-scale glycerol codigestion experiments, with continuous and intermittent dosing, were completed. The outcomes from these trials informed the implementation of a full-scale, 12-month glycerol codigestion trial at a wastewater treatment plant.
