Phosphorus recovery by sludge acidification and dewatering

A pilot-scale Danish study of phosphorus extraction from acidified anaerobic and aerobic sludge samples has revealed removal to be more effective from anaerobic sludges, even though the digested sludge alkalinity increases the total acid demand.
