Dissolved air flotation - Wikipedia

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 causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.

Overview of flotation as a wastewater treatment technique ...

The use of flotation is showing a great potential due to the high throughput of modern equipment, low sludge generation and the high efficiency of the separation schemes already available. It is concluded that this process will be soon incorporated as a technology in the minerals industry to treat these wastewaters and, when possible, to recycle process water and materials.

Wastewater treatment by flotation - SciELO

The flotation process, when applied in wastewater treatment, use methods of air injection in such a way that small air bubbles (<0.1mm) should be formed. This is necessary due to the small size, low density and usually hydrophilic properties of the solids to be removed.
