liquid sludge conversation to dry sludge

liquid sludge conversation to dry sludge

Sludgeconsolidation processes can be categorised as either thickening or dewatering, depending on the extent of water removal. Thickenedsludgeretains the free-flowingliquid-like properties ofsludge. Dewateredsludge(called cake) has a higher suspended solids concentration. The cake does not flow like aliquidand so cannot be pumped.
