Sludge Thickening

Gravity Thickener. A gravity thickener is much like a clarifier in that the sludge/water mixture enters through the center in the influent line. This reduces the hydraulic force of water and sludge that enters the thickener. In the lower portion of the thickener is the sludge rake, which moves sludge to the hopper, where sludge is collected and ...

Beginners guide to thickeners

Many thickener installations operate with water recovery below design limits largely through conservative control and low prioritization of thickener optimization. The operation of the thickener must accommodate fluctuations – control for disturbances – in the process feed stream to deliver a clear overflow and thickened underflow.
