Dissolved Air Flotation Process in Wastewater Treatment
Dissolved air flotation (DAF) is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters – and other waters – by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure – then releases it at atmospheric pressure.
Evaluating dissolved air flotation for oil/water separation …
Dissolved air flotation (DAF) is a commonly used treatment process in many facilities for treating oil/water emulsions. In a DAF process, air bubbles are injected to reduce the net density of the oil droplets where the adhesion of air bubbles on these droplets provides sufficient buoyancy for oil/water separation [9]. Fine air bubbles (in the ...

Dissolved Air Flotation
Dissolved air is the most common type of flotation gas used in potable water treatment. The dissolved air flotation (DAF) process mixes a clarified stream from the outlet of the unit with air at 3–9 bar, to produce a supersaturated (compared with saturation at atmospheric pressure) solution of air in water.
