flotation cells mechanical

In mechanical flotation cells, where the specific power is – kW/m 3, the bubble generation occurs in the rotor–stator zone. In this zone, due to the external inertial stress from turbulent pressure fluctuations, gas breakage is the prevailing bubble formation mechanism.

In treating oily water from oil refineries, the separation of oil by mechanical flotation is called froth flotation. It is achieved by adding an organic coagulant or demulsifying agent. Flotation units are constructed with three or four cells in series. Froth flotation by injection of air may also be used for the separation of surfactants.
