NeoTech DAF process consists of super saturation of discharge water from the effluent end of the system tank with air. The super saturated water stream is then mixed with the waste stream and pressurized in pressure tube. A sudden release of pressure from the saturated stream millions of microscopic bubbles form and attach themselves to the contaminants of oil and solids in the wastewater, thereby changing their buoyancy and floating them to the water surface where they can be skimmed and removed from the water.NeoTech also offer a combined chemical pretreatment to improve DAF solids removal efficiencies. The use of chemical flocculants with DAF is based on system efficiency, application contaminant characteristics and cost.Dissolved Air Flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended mattersuch as oil or solids. The removal is achieved by dissolving air in thewater or wastewater under pressure and then releasing the air atatmospheric pressure in a flotation tank basin. The released air formstiny bubbles which adhere to the suspended matter causing thesuspended matter to float to the surface of the water where it may thenbe removed by a skimming device.
