Sludge Thickening - an overview | ScienceDirect Topics

The first principle is used in grit chambers, and the second in vortex separators. Velocity-associated “centrifugal” forces may be used to enhance gravity separation. As well as the centrifuges used in sludge thickening, this is an important process in the “Pista” type grit separator. Some form of washing is recommended for collected grit.

Bitumen Extraction Explained | Oil Sands Magazine

Gravity separation cells are large diameter cone-bottomed vessels with a steep side slope. The shape of the vessel facilitates the separation of heavy solids from the light, aerated bitumen froth. Oil sands slurry from the Hydrotransport pipeline enters the vessels through a feedwell, which evenly distributes the slurry below the froth layer.
