Sludge Thickening an overview ScienceDirect Topics
As part of a general plant upgrade, a centrifuge sludge thickening system was installed to separate liquid from the sludge more effectively, creating a thickened sludge with 6–8% dry solids content. This enabled much more efficient transportation—an average of only one tanker per week is now needed—cutting transport costs significantly.
Sludge thickening
Thickening aims at increasing the dryness (content of dried matters) of sludge without modifiying the liquid character of the sludge. This thickening can be done simply by gravitating mechanic ways (thickening or flottation).Dryness of thickened sludge at the gravity belt thickener outlet can range between 6 and 8%.
Sludge Thickening an overview ScienceDirect Topics
Sludge is introduced at a central feed well and the supernatant overflows a peripheral weir. The sludge is thickened by the action of a specially designed rake which also moves the thickened sludge to a central hopper, of included angle 60°, for intermittent discharge under hydrostatic head (Albertson, 1992).
HUBER Solutions for Sludge Thickening Huber
Thickening is the first step for reducing the sludge volume by removal of free sludge water. Thin sludge is concentrated to thick sludge. Thick sludge has a higher viscosity, but must still be pumpable. Sludge settles in gravity thickeners and is compressed by the weight of its own solids.
