Abstract:
1. A method for treating microbial growth in an industrial water system containing an anionic anti-scale or an anionic anti-corrosive agent, or both an anionic anti-scale and anionic anti-corrosive agent comprising: adding a composition to a body of water in an industrial water system, the body of water comprising an anionic anti-scaling or anionic anti-corrosive agent or both an anionic anti-scaling and anti-corrosive agent and the composition comprising: a peroxide source, which provides a peroxide, a phase transfer agent comprising at least one from among a positively charged quaternary ammonium compound, a positively charged phosphonium salt, and a positively charged sulfonium salt, and optionally, adding an alkaline compound to the composition or body of water to raise the pH of the body of water to a pH value of greater than 7.0, wherein the composition interferes less with the anionic anti-scaling, anionic anti-corrosive agent, or both the anionic anti-scaling and anionic anti-corrosive agents than a composition without an peroxide source and the composition has antimicrobial or biocidal activity.
