Investigation and Design of a Picket Fence Thickener for

Themon thickener is the Circular Basin Type Thickener. The Flocculant treated feed slurry enters through the central feed well or central diffuser drum, which disperses the feed gently into the thickener. The feed suspension falls until it reaches a height where its density matches the density of the surrounding suspension and it spreads at that level. Solids concentration increases

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
