Considerations and Parameters in Thickener Selection

A controlled underflow is necessary. Thickener selection is the appliion of these needs to the basic process concepts. Perhaps the most conservative approach to sizing and appliion is the use of comparative data from similar plants or similar industries. Thickeners areroutinely used in a great number of industries from which there is

High Rate Thickeners

Description. The HighRate 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 highrate machines. Furthermore, they are normally positioned far away from the center of the plant so to allow
