EDDY Pump is Top Choice for Gravity Thickener Processing

Gravity thickeners are similar to clarifier tanks and settling tanks that allow for suspended solids from slurries to gradually sink to the bottom of the tank. As the solids collect at the bottom of the tank, it forms into a sludge like material that needs to be constantly removed by the use of high powered non clog slurry pumps for disposal.

Difference Between Clarifier and Thickener

HOW THICKENERS WORK. Clean water rises to the top of the Thickener and overflows a peripheral weir into a collection launder. Once collected in the overflow launder, clean water exits through a single flanged outlet and can flow via gravity to a water storage tank or clean water pond for reuse.

Improve Clarifier and Thickener Design and Operation

Clarifiers and thickeners are essentially ide ntical units; a clarifier produces clean water, while a thickener concentrates a solids slurry as the desired product. In this discussion, thickener will be used to describe both units. Also, a gravity separation of solids from water is assumed to take place.
