Abstract (en)

[origin: WO9832538A2] A device for induced air flotation that uses a self aspirating and radially discharging funnel-shaped nozzle for producing extremely fine gas bubbles. The nozzle in addition may be used with a flotation cell that consists of a mixing chamber and an annular channel around it thereby enabling vertical motion of the liquid through from top to bottom of the annular channel.
