dissolved air flotation - an overview | ScienceDirect Topics

2.5.1 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 the atmosphere, the dissolved air comes out of the liquid forming fine bubbles bringing fine particles with them.
