Principal of Operation Dissolved Air Flotation. DAF or Dissolved Air Flotation is a simple but ingenious concept. Make tiny bubbles by dissolving gas (air typically) into water under pressure according to Henrys Law of gas whereby the pressure applied to gas will dissolve it into liquid (water).
DAF Wastewater Treatment System. Dissolved air flotation [DAF] is a treatment process which removes suspended solids, oil and grease from wastewater. Many applications use the DAF process but it is particularly useful for industrial wastewater treatment as it can reduce COD by up to 90%. Dissolved air flotation involves the creation of tiny air
