Continuous-Flow Aerobic Granular Sludge Treatment of Dairy Wastewater

The authors conducted a study on treating synthetic dairy wastewater using aerobic granular sludge (AGS) in laboratory-scale continuous flow reactor (CFR) system. system consisted of an anaerobic reactor, and settling sedimentation tank, with different hydraulic retention times tested over 90-day period. monitored characteristics effluent treatment performance found that the achieved excellent removal rates for chemical oxygen demand total carbon, exceeding 90%. As result, met Portuguese laws direct release into water environment. Moreover, AGS improved capacity from 272 to 80 mL/g, demonstrating its effectiveness as viable alternative this type effluent.
