  9. Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
    5/22/2006

    Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks.
