Dissolved air flotation(DAF), which is applied more and more to water plants, is reviewed, including its origin, its development in China and other countries and its advantages and disadvantages.Besides, the theory of dissolved air flotation is introduced from the point of view of thermodynamics, kinetics and the hydraulic characteristics of the flotation tank, which would be beneficial to the designers and the plant operators.At the end of this paper, the types of source water to which DAF process is more appropriate is discussed.
Key words： flotation; water supply treatment; low tunbidity water
