Gravity separation

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical i.e. the components of the mixture have different specific weight.

Difference Between Clarifier and Thickener

The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids. Thickeners are used to concentrate solids, while clarifiers are used to purify liquids. A thickener will give you a high density underflow while a clarifier will not.

The object of efficient thickening is to obtain a high dry solids content in a short time period. Thus, quantification expressions for the extent and rate of gravity thickening are important. The extent of thickening is a function of the amount of water removed during settling and is expressed as the solids concentration of thickened sludge.
