  • Dissolved Air / Gas Flotation Separators Sewage

    Dissolved Air Flotation (DAF) System Dissolved Air Flotation (DAF) is a PhysioChemical Treatment where air is intimately contacted with an aqueous stream at high pressure, dissolving the air. The pressure on the liquid is reduced through a back pressure valve, thereby releasing micronsized bubbles that sweep suspended solids and oil from the polluted stream to the surface of the airflotation unit.
