How to Size a Thickener 911 Metallurgist

08/03/2016· A = Thickener area in square feet per ton of dry solids thickened in 24 hours. F = Initial density (Parts Water to Sol­ids by weight). D = Final density to which pulp will settle or density at which you want to discharge pulp from thickener. R = Settling rate in feet per hour. Usually it is desired to discharge pulp from the thickener at its final density as shown in the above test. However

Thickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume. An alternative to gravity thickening is dissolved air flotation.

21/08/2018· Gravity thickeners consist of open tanks with a feed inlet at the top and a means of collecting the sludge at the bottom by a rake. As the contents are slowly stirred by the rake rotation, the solids settle and are drawn off the bottom in a continuous underflow. Gases escape from the surface, and clear solution is removed by the overflow weir. Chemicals are added to the feed to aid settling
