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.

flotation dewatering gravity

Mechanical thickening is usually done with either a rotary drum, gravity belt, DAF or centrifuge but a good three belt press can dual function as a thickening device by utilizing the gravity deck portion of the press and an earlier take off point. This can offer substantial saving if a facility can combine thickening and dewatering in one unit.
