What Is a Hi-Rate Thickener? Hi-Rate Thickeners are advanced sedimentation equipment designed to accelerate the settling process of solids in slurry. Unlike conventional thickeners, they use flocculants and specialised feed well designs to optimise sedimentation. This results in: Faster separation of solids from liquids. Reduced slurry volume.

Feed Solid Concentration. Conventional thickener design uses center underflow outlets with the floor sloped at 1:12–2:12 toward the center. Lighter duty applications such as clarifiers usually use a 1:12 slope. ... The center outlet is typically a 45-degree cone on bridge-type thickeners and a trench on center column thickeners.
