Flotation thickeners

Dissolved air flotation (DAF) provides thickening of sludges by encouraging the solids to float to the surface, rather than allowing them to sink to the tank base as with gravity thickening, where they can be removed by a skimmer. DAF is applied when the sludge solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by conventional settling.

How do you solve a problem like PFAS?

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.
