Dissolved Air Flotation System
Products Description
DAF system dissolved air flotation units for waste water treatment plant is an efficient flotation method for water clarification.The term refers to the method of producing flotation by dissolving air in the water under pressure and then releasing the pressure. When the pressure is released the solution becomes supersaturated with air as millions of small bubbles form. These bubbles attach to any particles in the water causing their density to become less than that of water. The particles then rapidly float to the surface for collection and removal, leaving the clarified water behind.
