Dissolved air flotation (DAF) Dissolved air flotation (DAF) represents the state of the art for the separation of suspended solids in modern paper mills. Dissolved air flotation is used in treating white water from the paper machine, in clarifying filtrates from thickening stages in stock preparation and in separating solids from mill effluent.
