Dissolved Air FLoatation

Dissolved air flotation (DAF) is a water treatment  process that clarifies Waste water  (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the wateror 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 tofloat to the surface of the water where it may then be removed by a skimming device
