Jun 18, 2020 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.

Flotation. Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation DAF process mixes a clarified stream from the outlet of the unit with air at 39 bar, to produce a supersaturated compared with saturation at atmospheric pressure solution of air
From Wikipedia Dissolved Air Flotation Dissolved air flotation DAF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin.
