Dissolved air flotation - Wikipedia

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 flotationTHE USE OF DISSOLVED AIR FLOTATION IN MUNICIPAL,Flotation instead of sedimentation in chemical treatment plants The settling tank in traditional chemical treatment plants (or enhanced primary treatment plants) is designed for an overflow rate of 1-2 m/h. This may, however, be considerably increased by the use of polymers as flocculants.Comparing dissolved air flotation and conventional,,Dissolved air flotation (DAF) is generally considered more effective than sedimentation (S) in the treatment of algal-rich water.
