Beginners guide to thickeners - Metso Outotec

2017-6-16  Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.

Continuous Thickening Theory

2018-1-28  In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U. The rate at which solids move downward by gravity

Thickener - an overview ScienceDirect Topics

The most common thickener is the cylindrical continuous thickener (Fig. 10). Feed enters through a central feed well at the surface, and eventually settles into a thickened sludge blanket in a conical base, where a slowly revolving mechanism rakes it to a central discharge. Clear liquid overflows into a launder around the periphery of the tank.
