Centrifuges

Centrifugal dewatering increases the sludge concentration by encouraging the particles to migrate to the walls of a rapidly rotating cylindrical vessel under the influence of a centrifugal force. Relatively high rotation speeds are employed to produce a cake product having a substantially higher solids concentration than the thickened sludge product produced by centrifugal thickening.

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?
