Membrane thickeners

Membrane technology provides separation of suspended solids from liquid through a highly-selective permeable polymeric or ceramic material under positive or suction pressure. Membranes can therefore be used to thicken sludge by allowing water to pass through through the membrane, leaving the thickened solids on the unpermeated side.

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.
