Dissolved Air Flotation - an overview ScienceDirect Topics

5.3.5.1 Dissolved-Air Flotation. In the dissolved-air flotation system, a liquid stream saturated with pressurized air is added to the dissolved-air flotation unit, where it is mixed with the incoming feed. As the pressure returns to atmosphere, the dissolved air comes out of the liquid, forming fine bubbles that bring fine particles with them ...
