Dissolved Air Flotation

Dissolved Air Flotation - Wikipedia

Dissolved Air Flotation (DAF) is een waterbehandeling proces dat afvalwater (of andere types water) zuivert door het verwijderen van zwevende stoffen, zoals olie, vet of vaste stoffen. De verwijdering wordt verkregen door het oplossen van lucht in het toegevoegde water, gerecycleerde water of direct in het afvalwater onder druk en het daarna ...

Dissolved Air Flotation (DAF) Systems - Evoqua

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.

dissolved air flotation - an overview | ScienceDirect …

Dissolved air flotation is also usually combined with stone flocculation and is one of the most energy consuming methods of harvesting, so, it has not been considered here. Again, the ability of at least some strains of B. braunii in self-floating eliminates the requirement of the air flotation step.

Dissolved Air Flotation (DAF) Systems | Fluence

Our dissolved air flotation solutions provide high-quality, high-capacity, and efficient clarification. DAF works by producing a stream of microfine bubbles that attach to solids and lift them to the surface, where they can be removed by a surface scraping mechanism.
