An overview of oil–water separation using gas flotation …
A Sweep Factor, one of the design parameters used in gas flotation, defines the number of times per minute gas bubbles will contact with any particular volume element in the flotation cell (Juniel et al., 2004, Lee and Frankiewicz, 2004, Walsh, 2012). Higher collision probability can be realized by designing a flotation column with a larger ...
