High-rate thickeners also have a smaller tank volume, so less volume is required for storing the product if the tank has to be emptied. Because of this, high-rate thickeners can start up and shut down faster than conventional thickeners. However, due to their smaller size, high-rate thickeners require faster settling rates.

Thickeners are used primarily to settle water. Slurry enters the feed well where it is mixed with flocculant. The flocculant assists with settling the silts and foreign particles. The rakes slowly turn to capture the sludge which is directed to the discharge cone. Clearwater overflows the top of the thickener via a to be discharged back into the process.

Deep Cone Thickener. Deep cone thickener is a type of gravity settling equipment for strengthening flocculation and hydrostatic pressure compression. It was invented by the British National Coal Board. Its upper part is cylindrical and its lower part is conic with a small cone angle and a deep thickener tank. The structure is shown in Fig. 1.
