Thickeners are specialized viscosity-modifying ingredients added to obtain a required viscosity. Modern high-performance thickeners for aqueous, oil-based, and surfactant systems provide effective and efficient thickening at a minimal 0.5-2% use. Mild and naturally derived thickeners are preferable. Some are even more effective than conventional thickeners and leave a …

High Rate Thickeners High rate thickeners are designed specifically to maximise the flocculation efficiency of flocculants. They differ from conventional thickeners in feed well design, size and control. Unlike conventional thickeners, high rate thickeners must use flocculants. The basic design of a high rate thickener is below.

A key component of most thickener operations is the motion of a thickened sediment across the floor of the tank to an underflow, usually located centrally. In most conventional thickeners and in many high rate and paste thickeners, this transport is aided by a set of two or four rake arms (see the schematics in Fig. 1, Fig. 3).
