Dissolved Air Flotation - an overview | ScienceDirect Topics

Dissolved Air Flotation. DAF technology can range from simple circular basins equipped with a configuration of submersible nozzles, which bubble pressurized air up through a near stagnant pool of wastewater, to dynamic systems designed with multiple compartments, which capitalize on different water retention times in each compartment and a combination of settling, flotation, and impingement to ...

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 or basin. The released air forms tiny bubbles which adhere to the suspended ...
