Dissolved air flotation Description
Dissolved air flotation is one of the most effective methods whose specific gravity is close to 1.0 from water.Dissolved air flotation is liquid/solid or liquid/liquid separation process to remove tiny suspended solids that density close to the water, colloid , oil and grease etc. Benenv dissolved air flotation is an innovation combined with traditional dissolved air flotation concept and modern technology.
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. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device.
