FLOTATION

In natural flotation, release of gas in the form of bubbles from, for example, a fermentation is the cause of scum at the surface of the liquid. Aided flotation is a natural flotation improved by blowing air bubbles into the suspension, and is useful for the separation of greases dispersed in a turbid liquid.
