ResultThe flotation tank is divided into the contact zone and the separation zone [4]. In the contact zone, the supersaturated water is injected into the flotation tank through a nozzle. The resultant pressure reduction releases air from the solution as micro-bubbles, i.e., bubbles with diameters ranging from 10 to 100 μm.
