Since 1980, more than one quarter of the activated sludge biotreatment systems installed in Canadian mills have been of the type designed to enclose pure oxygen. These designs were selected in part for their compact footprints and partly on claims of their lower sludge production and their ability to handle foul condensates.This review shows that these systems are operated over a surprisingly wide range of volumetric organic loadings and ratios of food to microorganisms (F/M). Nevertheless, their performance in meeting effluent regulations for BOD, TSS, and acute toxicity has been as good as that of other activated-sludge designs. Application: Mills that operate oxygen activated sludge systems are generally satisfied with their performance.
