Dissolved Air Flotation Process in Wastewater Treatment

Superficial air flotation (SAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as grease 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 basin. More

DAF_Dissolved Air Flotator - Paramount Limited

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD 5), and oils and greases (O&G) from a wastewater stream. Contaminants are removed through the use of a dissolved air-in-water solution produced by injecting air under pressure into a recycle stream of clarified DAF effluent.

DAF - Dissolved Air Flotation | Wastewater Treatment Systems

Dissolved air flotation operates on the principal of the transfer of floc to the surface of water through attachment of air bubbles to the floc. The floc accumulated on the surface, known as the ‘float’, is skimmed off as sludge (Section 7.19).The clarified water is removed from the bottom and is sometimes called the subnatant or ‘floated’ water.
