The air flotation machine is a dissolved air system that generates a large number of fine bubbles in the water. The air is attached to the suspended particles in the form of highly dispersed tiny bubbles, resulting in a state where the density is less than that of water. ...

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 ...
