Solid – Liquid Separation – Thickening
The separation of solids from liquids is usually achieved by gravity sedimentation in thickeners. For fine particles this is a slow process. In general, 75–80 % of the water can be separated and removed by thickeners. For further water removal, filters are used where in excess of 90% of the water can be removed.

Sludge treatment − gravity thickening | Sludge Processing
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.

How to Operate a Thickener
Keep the worm chamber on the drive mechanism full of oil, and take care of the grease fittings daily. The lifting screw gear ought to be greased well, and it is a good idea to keep grease on the central shaft for about a foot below the worm gear. And don't fall into the thickener; it doesn't look well.
