ABSTRACT:
To increase the efficiency of the gas transfer in an element for the transfer of gas into liquids, in particular, for the transfer of oxygen in sewage treatment plants, with a porous gas transfer member into which gas is introduced via a feeder line and after passage through a porous gas transfer member is given off in the form of gas bubbles into the liquid surrounding the gas transfer member, it is proposed that the gas transfer member be in the form of a circular-cylindrical pipe consisting of porous material which is closed at both end faces by an end section made of porous material, and that the pipe be horizontally and sealingly positioned on a gas feeder line which opens into the pipe on the lower side of the pipe halfway between the two end faces.
