Thickening and Clarification Introduction Thickeners are used in continuous process applications where liquid solid separation by sedimentation is involved. Thickeners have three basic purposes Concentration, or raising the density of a mixture of solids and liquids (feed slurry). Clarification, which involves removing solids from the mixture.

Difference Between Clarifier and Thickener

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.
