  • How Dissolved Air Flotation Systems For Water Treatment

    Dissolved air flotation DAF is a water treatment process designed to remove oils, solids, and greases. In fact, the process helps clarify wastewaters and other waters by eliminating different types of suspended matter. The DAF process dissolves air in the water under pressure then releases it at atmospheric pressure.
