Sludge Thickening,Sludge Thickening Process,Thickening Process

Sludge thickening is a a low investment process used commonly in wastewater treatment plants to remove as much water as possible from the liquid sludge. The method involves increasing the concentration of the solids in the sludge so that they can be easily dewatered.

Gravity Thickening SpringerLink

Thickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes.

How a Thickener Works Mineral Processing Metallurgy

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.
