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 from the bottom and is sometimes called the subnatant or ‘floated’ water.

Dissolved air flotation Wikipedia

Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil 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. The released air forms tiny bubbles which adhere to the suspended matter

Gas dispersion measurements in a flotation cell

Nov 01, 2003· In other words, measurements of local superficial gas velocity give an indication of how the incoming air is dispersed in a flotation cell (Gorain et al., 1996). During the last decade, several invasive techniques have been suggested to allow the gas rate to

dispersed-air flotation and this can be achieved by measurement of the contact angle. This is the angle between the plane surface of a solid particle and an air bubble in water (Fig. 1). At equilibrium the interfacial tensions at a point of three-phase contact must balance, thus T = T + T AS WS AW CosG or
