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 (DAF) units, when compared for instance to plain sedimentation units, are economic and performing machines to achieve separation of suspended solids, and/or sludge thickening, floating them through the action of a rising air stream. Air is dissolved under pressure into water to produce, once pressure is released, air bubbles with a diameter of 20 to 50 microns that

Once this portion of saturated effluent enters the flotation tank, the pressure is released back to atmospheric pressure. This immediately results in the recycled flow becoming supersaturated, resulting in the generation of micro bubbles as the dissolved air comes back out of solution. These bubbles attach to, and form within, the solids or chemical flocs entering the vessel, causing them to
