How a Thickener Works

Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were

Principle of rake thickener Xinhai

Here is the working principle of rake thickener. The rake thickener consists of circular thickening tank, central column, feed pipe, a steady flow tube, and rake frame. Under the action of gravity, the flocculated solid particles gradually settled to the bottom of the thickening tank.

Inclined Plate Clarifier Basic Theory of Operation

Inclined Plate Clarifier Basic Theory of Operation The Inclined Plate Clarifier, or Lamella, was first described and quantified by Hazen in 1904. The Lamella consists of a series of closely spaced flat plates inclined at an angle of from 45 to 60 degrees from horizontal.

Thickener an overview ScienceDirect Topics

In principle, this method allows the minimum area to be calculated, and also allows assessment of a thickener's ability to tolerate overload (i.e., act as a surge tank). In practice, the method assumes an ideal slurry: one in which the settling rate is a function of local concentration only.

Thickeners McLanahan

Thickeners should be viewed as a continuous settling and thickening process. When the Thickener is in a steady state, the solids are being withdrawn at the same rate as which they are being fed. Therefore, a principle of mass in equal to the mass out should be observed, and instruments for measuring both the feed, as well as the underflow

Rotary vacuum-drum filter Wikipedia

A Rotary Vacuum Filter Drum consists of a drum rotating in a tub of liquid to be filtered.. The technique is well suited to slurries, and liquids with a high solid content, which could clog other forms of filter.The drum is pre-coated with a filter aid, typically of diatomaceous earth (DE) or Perlite.After pre-coat has been applied, the liquid to be filtered is sent to the tub below the drum.

High Rate Thickeners Solid Liquid Separation

Description. The High-Rate thickeners became popular in the mid 1980's and are relatively newcomers to the sedimentation line of equipment. As already discussed previously Thickeners are a major component in a plant layout and occupy large spaces which may be saved by introducing high-rate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow

The feed slurry is pumped or fed by gravity to the thickener and shall have the energy to aid mixing of flocculent solution with it. The feed well is sized adequately to take care of the venting of the entrapped air in the feed
