Beschreibung
Zusammenfassung:	A method of reducing activity of sulfur and/or nitrogen metabolizing bacteria is provided. The method includes adding a composition of an alkali metal salt of chlorite and/or an alkali metal salt of chlorate and hydrogen peroxide to process water of a cooling tower and increasing a concentration of the composition from about 0 ppm to about 300 ppm in about 1 to about 100 minutes. The method results in significant savings of caustic and reduces sulfur and/or nitrogen metabolizing bacteria in the process water. L'invention concerne un procédé de réduction de l'activité de bactéries métabolisant le soufre et/ou l'azote. Le procédé comprend l'ajout d'une composition d'un sel de métal alcalin de chlorite et/ou d'un sel de métal alcalin de chlorate et de peroxyde d'hydrogène pour traiter l'eau d'une tour de refroidissement et l'augmentation d'une concentration de la composition d'environ 0 ppm à environ 300 ppm en environ 1 à environ 100 minutes. Le procédé permet des économies significatives de caustique et réduit les bactéries métabolisant le soufre et/ou l'azote dans l'eau de traitement.
