Abstract

1303163 Aerating liquids BADISCHE ANILIN- & SODA-FABRIK AG 7 May 1970 [8 May 1969] 22051/70 Heading B1C Liquid is aerated by means of an ejector which dips into the liquid. The ejector has a central tube 3 through which liquid flows, e.g. from a pump, and induces a flow of air through a surrounding tube 4. The air and liquid pass through a mixing tube 5 completely immersed in the liquid, inducing through the tube 5 the circulation of the liquid in the container. The liquid may be a lake or river, or be in a container 1 as shown. The process may be used to speed up fermentations, or to aerate sewage. The liquid flows through the tube 3 at between 5 and 100 m/sec., the diameter of the mixing tube 5 is 2-20 times the diameter of the tube 3, and the length of the mixing tube 5 is 2-30 times the diameter of the mixing tube.
