Dissolved air flotation

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...
