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 …
