Fundamentals of Dissolved Air Flotation | SpringerLink

It is this second phenomenon that is used for generating the air microbubbles necessary for dissolved air flotation. The implementation is quite simple: the pressure of the water is increased from about 1 bar (atmospheric pressure) to a pressure usually between 4 and 6 bar and, at the same time, air is injected (at the same pressure as the water, of course) so that it can dissolve …
