Drinking Water Disinfection [Case Studies White Paper]

  1. Direct Filtration Of Spring Water
    10/23/2012

    The Franklin Water Treatment Plant, near the Utah/Idaho state border, serves approximately 600 residents. Traditionally, water was drawn from springs and chlorinated.

  2. Water Utility Turns To State-Of-The-Art UV Technology To Help Address Drought
    11/24/2014

    The 2013 year was the driest in recorded history with many areas of the San Joaquin Valley reporting groundwater levels more than 100 feet below previous historical lows. 

  3. Ozone System Delivers For Miramar Water Treatment Plant Upgrade And Expansion Project
    8/15/2015

    A combination of growing demand, aging infrastructure and regulatory requirements acted as drivers for a new ozone system at the Miramar Water Treatment Plant in San Diego, CA.

  4. Monitoring Water Quality With UVC LEDs
    11/2/2015

    Rapid detection of changes in water quality is critical in water delivery systems, wastewater treatment, and industrial plants for process optimization, environmental regulatory requirements, and consumer health.

  5. Ozone Disinfection System Provides Treatment In Arizona
    6/19/2015

    Water is disinfected before it enters the distribution system to ensure that dangerous microbial contaminants are killed.

  6. 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. 

  7. Is Coagulation Followed By Filtration Viable To Remove Arsenic When Raw Water Arsenic Levels Are High?
    10/9/2018

    The objective of the pilot study was to demonstrate “proof of concept” if coagulation followed by filtration was a viable technology to remove arsenic in water from Well No. 6 when raw water arsenic levels are so high, >70 ppb. Preparations were made to reduce the pH of the raw water if it was required. Also, two unique arsenic adsorptive medias were evaluated as a final polishing step to the effluent of the coagulation/filtration process.

  8. Clarification And Filtration Upgrades Using ACTIFLO Technology
    1/12/2017

    The City of Somersworth has a historical background dating back to the early 1900s when it became the first community to start using chlorine to disinfect it’s drinking water.

  9. Retrofit Significantly Reduces Backwash Cycle Interval, Duration And Water Use For Georgia Utility
    5/1/2017

    The North Columbus Resource Facility recently completed a $12-million replacement of its settled water filtration, removing the existing Wheeler filters, their three-part media and 10-inch poured concrete underdrains, which were no longer efficient.

  10. Coastside County Water District, California Drives System Reliability And Sustainability With Microclor® On‐Site Hypochlorite Generation, Encore® Metering Pumps And PolyBlend® Polymer Activation
    7/18/2018

    Located in northern California, the Coastside County Water District (CCWD) provides treated water to the scenic town of Half Moon Bay and several unincorporated communities in the area. The system is served by two treatment plants, the Nunes Water Treatment Plant (4.5 MGD) and Denniston Creek Water Treatment Plant (1.0 MGD) and water is distributed through about 100 miles of transmission and distribution pipe.
