  • Application Guide: Dissolved Air Flotation Optimization | Hach

    In industrial processing plants, a Air DAF is often used to reduce loadings and clarify wastewater. Tiny air bubbles are released into the tank causing small particulates to float to the top where they are skimmed off. To remove larger suspended solids, coagulant is dosed into the feed water—this helps to speed up

  • What is Dissolved Air Flotation DAF

    From Wikipedia: Air " air DAF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a tank or basin
