Use Of Coupled Biological Dissolved Air Flotation Processes

Dissolved air flotation. Dissolved air flotation DAF is a water treatment process that clarifies wastewater by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin.
