Improve Clarifier and Thickener Design and Operation

Guess the thickener area for the first iteration. Several iterations of area may be required to achieve a practical thickener size and pumping rate. For a circular thickener with a 15.24 m (50 f t) dia.: A= Pi r 2 = 182.4 m 2 (7) The applied solids feed rate can now be calculated as a flux - see Eqs. 8a and 8b.

Beginners Guide to Thickeners - Outotec

In high rate thickener (HRT) designs the rise rate or solids loading will dictate the required tank diameter for any given throughput. In high compression (HCT) and paste (PT) applications the bed depth or the mass of solids in the thickener must also be selected to ensure the desired underflow density from the thickener is achieved.

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 ...
