Dissolved Air FlotationKemco Systems
Dissolved air flotation is a water treatment process that clarifies wastewater by removal of suspended solids oils greases BOD COD and metals. This is achieved by dissolving air in the wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank. The released air forms tiny bubbles which adhere to the

Sludge treatment − dissolved air flotation Sludge
2020-6-18 · How DAF works. Dissolved air flotation (DAF) provides thickening of sludges (i.e. thickens the sludge) by encouraging the solids to float to the surface rather than allowing them to sink as in gravity thickening.. DAF is applied to increase the sludge solids concentration when these solids are neutrally buoyant (i.e. neither sink nor float) and so cannot be readily removed by settling.
