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.

Pretty intense: the intensification of sewage sludge processes

Sludge intensification processes increase the sewage sludge solids concentration through thickening/dewatering or the biogas generation by digestion. But at what point do you stop extracting more water from the sludge or enhancing biogas production?
