Dissolved Air Flotation - an overview ScienceDirect

Dissolved air flotation. Heavier than water particles can also be made to float. Dissolved air flotation, the most common approach, works by attaching small bubbles of air to suspended solids. The bubbles are generated by saturating a recycled stream of water with air under pressure, then releasing the pressure rapidly to produce clouds of microbubbles.

Dissolved Air Flotation - an overview ScienceDirect

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.

From the time of the early 20 th century, Dissolved Air Flotation (DAF) had been used in the separation process. In the DAF system, air is dissolved in the wastewater under a pressure of several atmospheres, followed by release of the pressure to the atmospheric level. In this case, the recycle flow system has been studied. For this kind of system, a portion of the DAF effluent is being ...
