Abstract (en)

[origin: EP0401721A2] For introducing gas microbubbles into a liquid, aeration elements (12) which are charged with gas via a gas supply line (14) are arranged in the bottom region of a container (10). The aeration elements are part of the gas supply line. The weight of the aeration elements with the gas supply line is selected so that special fixtures for the gas supply line are not necessary. <IMAGE>
