· Dissolved Air Flotation works on the principle of letting air, dissolved in water under pressure, form micro bubbles (10-50 micron) at the bottom of a tank. The microbubbles rise up to the surface, and as they form and grow, the bubbles take oil, greases, and small solids with them. The physics of this process are described below.

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.

Dissolved Air Flotation (DAF) is a water treatment process that removes suspended solids, oil, and grease from wastewater by using air bubbles as a flotation agent. The process works by adding small air bubbles to the wastewater, which cause the suspended particles to float to the surface, where they are removed by skimming.

Dissolved Air Flotation Systems-also known as DAF systems or DAF units-are a highly effective means of reducing TSS, BOD, COD and FOG in wastewater from all manner of sources. This is achieved by dissolving air in the water which then releases tiny bubbles. These bubbles adhere to the suspended matter, causing them to float to the surface

In dissolved air flotation (DAF), relatively small air bubbles (approximately in 10–100 μm) are formed when air is dissolved in a cultivation solution under a high-pressure condition [45, 60 ]. The suspended cells are forced to rise to the surface due to the air bubbles and then collected by skimming [ 8 ].
