Dissolved air flotation - Wikipedia
Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be remove

Separation of oil from water by dissolved air flotation
2002年9月4日 Measurements indicated that a saturator efficiency of about 90% was achieved and it was found that increasing the working pressure of saturator had less effect in the separation of oil droplets than increasing recycle ratio. Optimum conditions for separation are obtained with an air to oil ratio of 0.0075 corresponding to a recycle ratio

Folded Flow® Dissolved Air Flotation Separator - SAWEA
The Folded Flow® dissolved air flotation (DAF) separator is a significant innovation in water and wastewater flotation technology. Simple in concept, it “folds” the flow by removing effluent from the same end of the tank as the influent is introduced. This results in a higher hydraulic loading rate. The Folded Flow® hydraulic design takes ...
