Abstract

Problems in co-treating landfill leachate and sewage in the wastewater treatment plant in Fredericton. N.B.. Canada, led to the study of field samples and laboratory experiments. Batch reactors fed with settled sewage were operated under different leachate contents to evaluate some kinetic parameters The waste characteristics were analyzed. Leachate toxicity was sufficiently reduced after on-site partial treatment and by sewage dilution. However, an increase in sludge production overloaded the sludge processing unit. Too much leachate addition to the sewage would inhibit biological oxidation. 1 Introduction Land
