G. M. Wesner, Wesner, El Dorado Hills Culp, W.N. Clarke · 1978
Information on the potential for on-site use of anaerobic digester gas in municipal wastewater treatment plants is presented, and experience in on-site use in the U.S. is reviewed. Gas production data, process design criteria, and cost estimates for gas cleaning and storage and on-site electricity generation are presented. Energy requirements for activated-sludge treatment are compared with the energy available from anaerobic digestion.
