Dissolved Air Flotation Process in Wastewater 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.
