Container Type Dissolved Air Flotation Water Treatment Machine

Dissolved Air Flotation (DAF) 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.
