Jun 18, · Gravity thickening increases the solids concentration by allowing the particles to settle to the base of a vessel, producing a concentrated (thickened) solids stream at the vessel base and a supernatant (diluted) stream at the surface. Sedimentation, or settling, is the simplest of the thickening processes.

THICKENING. Traditionally used to reduce the amount of liquid in the digestion phase of the plant, thickening can be accomplished either through gravity style thickening tanks or mechanical means. Thickening tanks typically are larger and require more footprint, however they do not require buildings and yield polymer savings to achieve their ends.
