Isothiazolone biocides have been used effectively for decades to control microbial growth in a variety of industrial water treatment applications. The most frequently used product is a 3:1 ratio of 5-Chloro-2-Methyl-4-Isothiazolin-3- one (CMIT) and 2-Methyl-4-Isothiazolin-3-one (MIT). Typically CMIT/MIT is dosed into cooling systems as a liquid, but a novel solid version was recently developed. The CMIT/MIT solid is safer to handle and easier to transport that liquid biocide formulations. We report efficacy of CMIT/MIT against microorganisms, including Legionella, biofilm-formers and sulfate-reducers. The basic characteristics of the new solid tablet will be discussed based off of laboratory and field trials.
