Flotation consists of attaching air bubbles to suspended material, causing a net reduction of specific weight. The micron size bubbles are produced by dissolving air into the wastewater at elevated pressures followed by its subsequent release to atmospheric pressure. When the pressure is reduced to atmospheric conditions, the dissolved air, present in excess of saturation, is released as extremely fine bubbles attaching themselves to the suspended solids.

The solids, fats and floes float to the top of the dissolved air flotation cell and are removed by a skimming or scraping device. To effect flotation, a recycle pressurization system is used. Part of the treated effluent is drawn-off, into which air is dissolved at an elevated pressure and mixed downstream of the pressure release device.
