How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full.

Gravity Thickening

Gravity or flotation thickeners are normally used to accomplish thickening; centrifuges have also been used as sludge thickeners. Gravity thickening is the subject at hand while air flotation and centrifugation are presented in other chapters. 1.2.
