Versatile DAF Dissolved Air Flotation System Product Description Dissolved air flotation (DAF) is an efficient and fast method for separating solid particles from water and wastewater. Part of the treated wastewater is circulated into the dissolved air tank. Under the pressurized air state, the air is supersaturated and dissolved, and then mixed with the raw water with flocculant added at the entrance of the flotation tank. Due to the pressure reduction, the supersaturated
