Improve Clarifier and Thickener Design and Operation ... The compression regime is not well studied, and since it normally operates only at the very bottom cone of the thickener, it goes beyond conventional design requirements. ... This is done by constructing operating lines as illustrated in the thickener design example.

Thickeners are solidliquid separation equipment in which a slurry forming a pulp is fed to a tank provided with an internal mechanism in which solids are settled by gravity and can concentrate in the bottom of the tank and at the same time the clarified water overflows towards the surface to be collected in the peripheral launder of the tank.

Dynamic Thickeners. Dynamic Thickeners are commonly used for the separation of silt and water from sludge. They are circular tanks with a shallow cone section and internal rake. The sludge is fed into the top of the thickener where flocculent is added. The rake rotates slowly and gradually pulls the settled silt towards the central discharge port.
