What Is Dissolved Dissolved Air Flotation (daf)

Flotation can be used as a pre treatment in the purification process for biological purification for example but is often also used as the only step in the purification process The diagram shows the most commonly used set up This is referred to as dissolved air flotation (DAF) Air is dissolved in water under pressure (5 7 bar).The M W Watermark™ Dissolved Air Flotation (DAF) clarifier is a very effective tool in removing suspended solids fats oils metals and non soluble BOD from a waste stream In a DAF clarifier microscopic air bubbles are produced and mixed with the incoming wastewater.
