  • PERACID COMPOSITIONS WITH CONDUCTIVITY MONITORING CAPABILITY
    Publication number: 20220072591
    Abstract: Peroxycarboxylic acid compositions comprising compatible ionic compounds to deliver conductivity signals to enable monitoring of the peroxycarboxylic acid concentration by conductivity when diluted for use are disclosed. Methods of measuring peroxycarboxylic acid concentration by conductivity are also disclosed. Beneficially, conductivity measurement allows a user to determine concentration of the peroxycarboxylic acid at a point of use without cumbersome titration steps to determine the concentration providing various benefits at an application of use.
    Type: Application
    Filed: October 25, 2021
    Publication date: March 10, 2022
    Inventors: Junzhong Li, Caleb Power, Allison Prideaux, Richard K. Staub, Vaideeswaran Sivaswamy, John Paul Koehl
  • BIOCIDAL COMPOSITIONS WITH HYDRONIUM ION SOURCES FOR BIOFILM CONTROL
    Publication number: 20210368787
    Abstract: Biocide compositions efficacious for biofilm control, including treatment and/or prevention, comprising the synergistic combination of biocide(s) with a source of hydronium ions are disclosed. Methods of deactivating, removing and/or preventing biofilms with the compositions are also provided.
