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.
