    Dissolved air flotation DAF is a clarification process that utilizes air to remove suspended matter from the surface of treated water. DAF works by dissolving air under pressure and then releasing millions of tiny air bubbles into the water at atmospheric pressure. This process allows the dissolved air bubbles to adhere to a suspended matter ...

    In accordance with Henrys Law, more air is dissolved into a given volume of water at increased pressures. A 65 psi system requires less recycled water and produces smaller air bubbles than those operated at lower pressures. Recycled water serves to transport dissolved air to the flotation unit.
