摘要： A flotation device having a flotation tank for receiving liquid to be purified, a saturator for receiving a pressurized liquid-gas mixture and at least one feeder. A line leads from the saturator to the feeder through which the pressurized liquid-gas mixture may be introduced into the flotation tank. The feeder includes a flow channel that has different flow cross sectional areas along the extension thereof. The flow channel may be a Venturi nozzle.
