Sludge Thickening - an overview ScienceDirect Topics

Thickened sludge may be piped or tankered to a sewage works. Coagulant sludge may aid primary sedimentation of the sewage, thus reducing the solids load to the subsequent biological stages and helping in the removal of phosphate. Thickened waterworks sludge may also be mixed with digested sewage sludge for disposal.

THK Hybrid System Thickens Without Polymer Treatment ...

Kopper: Generally speaking with a gravity belt or rotary drum thickener, the polymer dose is 6 to 10 pounds per dry ton of solids. If we assume the avoidance of 8 pounds of polymer per dry ton, and a price of $2.50 per pound, a 120 gpm THK system processing 2,360 dry tons per year would yield annual polymer savings of $52,600.
