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
