| description | The present invention relates to a fast acting chemical treatment for preventing the generation of hydrogen sulfide odor by the microbial metabolic activities of sulfate reducing bacteria. Specifically, the invention relates to a method for preventing hydrogen sulfide odor generation in a sulfur species-containing aqueous medium, which includes adding to the aqueous medium chlorhexidine and salts thereof, in an amount effective for the purpose of a sulfide generation inhibition.
La présente invention porte sur un traitement chimique à action rapide pour empêcher la génération d'une odeur de sulfure d'hydrogène par les activités métaboliques microbiennes de bactéries réduisant les sulfates. De façon spécifique, l'invention porte sur un procédé pour empêcher la génération d'une odeur de sulfure d'hydrogène dans un milieu aqueux contenant des espèces de sulfure, ledit procédé comprenant l'addition au milieu aqueux de chlorhexidine et de sels de celle-ci, dans une quantité efficace dans le but d'empêcher la génération de sulfure. |
