SYSTEM AND METHOD FOR SULFUR BIOADAPTATION IN A STABLE DISPERSION FORM FOR INDUSTRIAL BIOREACTOR FEEDING

摘要

The invention refers to a system for sulfur (S) bioadaptation in a stable dispersion form for feeding industrial bioreactors, which are composed of: a) a tank with a liquid medium made up of a supernatant dilution or part of a sulfur oxidizing bacterial culture, b) a recirculating pump fed from the tank, and c) an eductor which is connected at its input to the recirculation pump, and connected at its output back to the tank, closing the recirculation circuit. There is a supply of S in fine powder form present in the eductor's feeding path. Where the supernatant or part of a sulfur oxidizing bacterial culture is diluted between 100 and 10 times in sulfur containing culture medium. The second aspect the invention discloses a method for sulfur bioadaptation in a stable dispersion form for feeding industrial bioreactors, which includes: a) initiating recirculation through a recirculation pump, in a tank which contains a liquid medium made up of a supernatant dilution or part of a sulfur oxidizing bacterial culture; b) connecting a supply of fine sulfur powder to an eductor, which is connected to the recirculation pump at its input, and its output connected back into the reservoir. The incorporated sulfur is pulverized by the suction produced within the eductor.
