Air is dissolved in water which is recycled from part of treated water under 3~5 atm, then released to the flotation tank under atmospheric condition. Released water generates micro bubbles by which the flocs are removed from water by flotation.
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 flocs float to the top of the dissolved air flotation cell and are removed by

Dissolved air flotation DAF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
With the use of the DAF, dissolved air flotation, or flotation assisted by the use of a mixture of water and microbubbles, properly located in a suitable plant or machine, the problem of a poor sedimentation is solved. Flotation of suspended solids is assisted by microscopic air bubbles that ensure removal efficiency up to 99 .
