Dissloved Air Flotation System

Product Description


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.

Technical parameters

Features

2. Recycle flow dissolved air flotation.
3. High efficiency pressurization system providing high quantity dissolved-air water to create large 
quantities of small bubbles.
4. Custom design on different dissolved air flotation equipment and recycle flow ratio according to 
the type of wastewater and treatment requirement to achieve target removal effect and stability.
5. Adjustable stainless steel chain type skimmer to suit the different quantity of sludge.
6. Integrated coagulation tank and or flocculation tank and cleaning water tank(as optional)is 
available to save the space and cost. 
7. Automatic and remote controllable.
8. Material of construction: carbon steel epoxy painted, carbon steel FRP line, stainless steel 
SS304/SS316L.
