Dissolved Air Flotation an overview ScienceDirect Topics

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

How Dissolved Air flotation Systems for Water Treatment

13/2/2018 Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters and other waters by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure then releases it at atmospheric pressure.
