How Dissolved Air flotation Systems for Water Treatment

Feb 13, 2018 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.
