Studies on the Control Index of Activated Sludge. VI. The Dimethyl Disulfide Formation Ability in Mixed Liquor of Activated Sludge.

Abstract

Formation of dimethyl disulfide (DMDS) from methionine added in the mixed liquor of activated sludge was investigated. Though the formation of DMDS was influenced by culture time, the content of methionine added, concentration of mixed liquor suspended solids, pH and temperature of the liquor, the condition of activated sludge influenced more significantly the formation of DMDS. As the condition of activated sludge became worse, the formation of DMDS increased, which was found on addition of not only L-methionine but also D-methionine.
