    Flocculation and Air Requirements for Dissolved Air Flotation

    Benchscale and pilotplant studies were used to investigate the effects of flocculation time and floe size on the performance of dissolved air flotation and to determine air requirements for three different types of water supplies The results show that long flocculation periods are not needed and suggest that floe particles of lo30 Frn should be prepared for flotation
