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) 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 ...

A better approach is to physically remove the algae and reduce the concentration of phosphorus in the water. A simple process of clarification via Dissolved Air Flotation (DAF) and phosphorus precipitation can stop an algae bloom in its tracks. We've used the DAF process many times to help with algae removal in surface bodies of water.
