Title: Microorganism growth rate acceleration - by magnets introducing paramagnetic oxygen molecules to microorganisms
Inventor: VOX WILHELM DIPL ING DR
IPC: C12N1/00
Filed: 1973-05-02
Abstract: The paramagnetic properties of oxygen are used to remove O2 from the atmospheric air and to introduce it to the fluid in an aeration tank of activated sludge treatment systems, or to microorganisms in the pharmaceutical, yeast or beer brewing industry. Magnets are arranged in a plane with pole shoes and magnetically soft iron plates either in or near the surface of the fluid to be aerated.
