SYNERGISTIC BLENDS OF ANTIMICROBIALS USEFUL FOR CONTROLLING MICROORGANISMS IN INDUSTRIAL PROCESSES

摘要

The present invention provides a method of controlling bacterial contamination using synergistic interactions of antimicrobials. The invention consists of combinations of chlorine dioxide and organic acid whose combined antimicrobial effect is greater than the sum of their individual activities, i.e., synergistic.

主权项

1. A method of controlling undesirable microorganism concentration in an aqueous system, the method comprising the steps of:
(a) introducing chlorine dioxide into an aqueous system and (b) introducing an organic acid into the aqueous system. wherein the organic acid is selected from the group consisting of citric acid, propionic acid, benzoic acid, and their salts and wherein the chlorine dioxide has a dosage rate of at least 1 ppm in the aqueous system being treated and the ratio of chlorine dioxide to organic acid is from 1:1 to 1:15,000.
