  • Method for measuring hydrogen peroxide in water
    Patent number: 10317381
    Abstract: An apparatus and method for measuring hydrogen peroxide concentration in water to an accuracy of 0.1 ppm comprises a colorimetric assay method to determine hydrogen peroxide concentration. The assay is monitored spectophotometrically at a desired wavelength. Each sample is corrected relative to a control sample and hydrogen peroxide concentration determined with respect to a standard curve.
    Type: Grant
    Filed: October 31, 2017
    Date of Patent: June 11, 2019
    Inventors: Jim Shubat, Gerben Op Den Buijs, Ludo Feyen

  • WATER INTEGRITY IN TREATMENT AND DISTRIBUTION SYSTEMS
    Publication number: 20150336824
    Abstract: As a measure of water integrity in water treatment and distribution systems, stabilized hydrogen peroxide is used as the secondary disinfectant. The concentration of hydrogen peroxide is monitored throughout the system and, if needed, additional hydrogen peroxide is injected into the system to maintain the level at established standards.
