Design and development of a novel thickener feedwell using

The feedwell performance in gravity thickeners and clarifiers relies on the efficient mixing between solid particles and flocculant to achieve effective flocculation, as well as energy dissipation of theg feed stream. A populationputational fluid dynamics PB CFD model has been developed and validated to provide new insights into the operation and performance of industrial

Thickener Feed System Design WesTech Engineering, Inc.

Conventional thickener feedwell designs have two maings: short circuiting, where the feed stream momentum carries the flow prematurely down and around the feedwell, past the shelf and deflector, and out of the feedwell and inefficient flocculation, where only a small area around the inlet of the feed provides good mixing.
