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.

PFAS (per- and polyfluoroalkyl substances) are generated from the breakdown of fluorinated polymers. The activation barrier for their breakdown is huge and the only fully commercialised processes possibly capable of destroying PFAS are thermochemical ones.
