Understanding the Thickening Process

The thickening process is the primary method of producing high solids slurries for the minerals industry. In simple terms, dewatering in a thickener involves gravity acting on the density difference between the solid particles and the carrier liquid (usually water), enabling the solid particles to settle.

Sludge thickening and stabilization processes

Oct 09, 2017· The equipment developed for thickening consists of gravity belt that moves over rollers driven by a variable- speed drive unit. The sludge is conditioned with polymer and fed into a fed/distribution box at one end, where the sludge is distributed evenly across the width of the moving belt. The water drains through the belt as the concentrating

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. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

Sludge Thickening an overview ScienceDirect Topics

Centrifuges, which are devices that amplify the forces at work in gravity separation, are of several different types. Centrifuges are used for separation of grit and other relatively heavy solids at the head end of wastewater treatment facilities, as well as for sludge thickening and/or dewatering at the “other end” of such facilities.
