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.

Another flotation method, called dissolved-air flotation (DAF), is common in the treatment of oily wastewater. In DAF, a stream of wastewater is saturated with air at elevated pressures up to 5 atm (40-70 psig). Bubbles are formed by a reduction in pressure as the pre-saturated water is forced to flow through needle valves or specific orifices.
