In the published literature, deflocculation of aerobic biological flocs under low dissolved oxygen (DO) (< 0.5 mg/L) conditions is typically reported as occurring as early as after 1 h of oxygen deficiency. However, results of this study involving aerobic sludge from three different sources repe...
