Dissolved Air Flotation an overview ScienceDirect Topics

Dissolved air flotation. Heavier than water particles can also be made to float. Dissolved air flotation, the most common approach, works by attaching small bubbles of air to suspended solids. The bubbles are generated by saturating a recycled stream of water with air under pressure, then releasing the pressure rapidly to produce clouds of
