Gravity thickeners

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. The thickener has the same design features as a primary sedimentation tank used for wastewater treatment, and most often has cylindrical geometry.

Biosolids are usually considered to be the useful fraction of the sewage sludge. They are generally higher in solids concentration and lower in pathogen content, having gone through a stabilisation process such as chemical dosing, digestion and/or drying.
