What is the Sludge Thickening Process in Water Treatment

Mar 06, 20180183;32;Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base. Dissolved air flotation is another type of sludge thickening process. Small air particles attach to the suspended solid material.
