CHAPTER 6: DESIGN AND CONSTRUCTION OF SLUDGE TREATMENT FACILITIES 6.1 THE APPROACH In STP, sludge means the following. • Primary sludge When raw sewage is settled in a primary clarifier, the suspended solids settle down by gravity. These are drawn out from the conical floor of the clarifier. This is called primary sludge (PS). It will have mostly

What is the Sludge Thickening Process in Water

06/03/2018 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. They enable the solids to break up and float to the surface. These suspended solids have a lower gravity than water

Sludge Thickening an overview ScienceDirect Topics

Sludge thickening is a process in which the solids concentration is increased and the total sludge volume is correspondingly decreased, but the sludge still behaves like a liquid instead of a solid. Thickening commonly produces sludge solids concentrations in the 3% to 5% range, whereas the point at which sludge begins to have the properties of a solid is between 15%

Gravity Thickener Design Example Wastewater Treatment

09/04/2021 Gravity Thickener Design Example. For the purposes of this example, the solids to be thickened are excess activated sludge with an initial solids concentration of 7 gm/l (0.434 lb/ft3). This sludge continuously enters the thickener, and the thickened sludge is continuously withdrawn at a concentration of 21 gm/l (1.302 lb/ft3).
