Abstract

The invention relates to a gas introduction system for introducing gas into a flowable medium in a vessel 1. To enable the gas to be introduced in the form of the finest bubbles possible, it is proposed to provide bottom nozzles 7 on the vessel bottom 6 for the introduction of gas into the medium, which nozzles are connected to quick-opening and -closing valves. <IMAGE>
