Sludge Thickeners The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5% from cone bottom clarifiers to 2%-4% from the rake bottom clarifiers. The sludge thickener must have sufficient capacity to accumulate and thicken the sludge between filter press cycles.
