Abstract

1405264 Aerating liquids BADISCHE ANILIN- & SODA-FABRIK AG 13 Oct 1972 [14 Oct 1971] 47273/72 Divided out of 1303163 Heading B1C In a process for oxygenating a body of liquid e.g. waste liquid containing activated sludge, air is introduced into the body of liquid together with a submerged jet of the liquid partly by the inductive action of the jet and partly by a pump. The jet of liquid having a speed of from 5 to 100 metres per second and being directed into an open-ended confined mixing zone 3 of hydraulic diameter 2 to 20 times the diameter of the liquid nozzle 1 and of length 2 to 30 times its hydraulic diameter. Liquid from the vessel 4 is circulated by a pump 7 and fresh waste liquor may be introduced continuously by a line 8, treated liquor overflowing at 5 to settling tanks. The combined air/liquid jet nozzle 1 may be located horizontally, vertically or at any intermediate position.
