  • Publication number: 20230278897
    Abstract: A system and method for controlling microbiological growth in a water system and premise plumbing system which uses stabilized hydrogen peroxide as a disinfectant and maintains water energy matrix control. Maintenance of stable hydrogen peroxide residual in the system in combination with active temperature monitoring enables better control of the water energy matrix and reduction of hot water temperature while maintaining microbiological control.

  • 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.

  • Publication number: 20170305768
    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 standard. An apparatus and method for measuring hydrogen peroxide concentration in water to an accuracy of 0.1 mg/L within water treatment and distribution systems 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.
