THICKENERS - Thermopedia

A thickener is an equipment structure used for the continuous gravity settling (sedimentation) of solids in suspensions. Suspension is fed into one or more basins or chambers and, whilst it is passing through, the solids settle out. The thickened solids are removed together with a …

Thickening - Resource Book

Continuous thickeners have undergone several modifications that have resulted from the development of a wide variety of organic polymeric flocculants. As a result, there are now two basic types of continuous thickeners: Conventional and High-rate. Conventional Thickeners These thickeners differ in the way they are built.

Paste Thickening and Backfill Mineral Industry Solutions

The type of paste thickener underflow generally used for surface stacking of tailings is called “thickened tailings.” Thickened tailings are a suspension of solids which are relatively non-settling and non- segregating and which have a higher concentration and viscosity than that of conventional tailings.

There are three main types of thickeners/clarifiers: bridge support, column support, and traction. In a bridge support thickener, such as the one shown below, the rakes and drive mechanism are suspended from a bridge that spans the diameter of the tank. They are usually only economical for diameters of fewer than 100 feet.

Continuous Thickening Theory

In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U.

Flour is the most common thickener used in recipes, from turkey gravy to apple pie, and for good reason: It’s versatile, and in most kitchens, it’s always on hand. But flour isn’t a pure starch (it contains protein and other components), so it has only about half the thickening power of other starches.
