Abstract

1294624 Apparatus for treating liquids with gases FRIED KRUPP GmbH 19 April 1971 [12 Feb 1970] 21540/71 Heading B1R Apparatus for treating liquid in a container with gas below the surface of the liquid comprises a flat disc having on its underside ribs which extend outwardly from a central portion thereof and which project from the disc into the liquid beneath it and having a central hole, a vertical rotatably mounted hollow shaft which serves to rotate the disc and communicates with the gas to be introduced into the liquid, and means to rotate the shaft. The ribs may be curved along their length and may project over the central hole.
