A few studies have proposed that the dissolved air flotation (DAF) process can certainly improve the effluent quality to some extent (Teixeira & Rosa 2006; Edzwald 2010). However, the presence of algae in raw water, low turbidity as well as high energy consumption and low adhesion efficiency pose great challenges to DAF in practical use.
