    Chatsworth Water Works Commission provides both water and wastewater services to the 5,000 residents of the cities of Chatsworth and Eton, GA.

  4. City Of Springfield, MO, Upgrades Disinfection System From Gas Chlorine To On‐Site Sodium Hypochlorite Generation
    7/24/2018

    In April 2013, City Utilities started up three Microclor Model MC‐1500 skid systems, each rated at 1,500 pounds per day of free available chlorine.

  5. Case Study Report For Z-88® Radium Removal – City Of San Angelo, TX
    8/9/2018

    The City of San Angelo, TX selected WRT’s Z-88 Radium Removal treatment system for reducing high levels of radium in their wells. The city’s Phase I treatment plan was fulfilled in 2014 with the installation of the first Z-88 Radium Removal treatment system. This large treatment facility has been reducing the levels of radium below the Maximum Contaminant Level (MCL) since it’s inception.

  6. A Multi Process Approach With One Single Solution
    10/22/2018

    A joint effort between the city of Hollister, the San Benito County Water District and the Sunny slope County Water District, the group proposed the West Hills Water Treatment Plant (WHWTP) project to improve drinking water quality, water supply reliability, and to balance regional water resources in the Hollister Urban Area (HUA). Historically, HUA relied primarily on local groundwater basins for meeting their drinking water demands. While groundwater met all drinking water regulations, it is high in minerals and hardness that often resulted in scaling and the need for further conditioning.

  7. Top Research Institute Turns To On-Site Generation For Drinking Water System
    9/18/2018

    As one of the top 20 American research institutes in the United States, Texas A&M has hundreds of laboratory facilities on its campus where a variety of proven water treatment technologies are used to control the quality of the water used in research.

  8. Arsenic Removal Pilot Study Meets California Standards
    10/3/2018

    Well water from several locations in Ridgecrest, California area is high in arsenic, carbonates and pH. Due to the high levels of arsenic, some wells are not being used to supply municipal water to the city of Ridgecrest and were shutdown. Due to local demand, the feasibility of treating these wells to remove most of the arsenic before blending with water from other wells is being investigated.

  9. Case Study Report For Z-88® Radium Removal – City of Bridgeton, NJ
    8/14/2018

    WRT’s Z-88® Radium Removal treatment system was selected to remove high concentrations of radium in two treatment facilities for the City of Bridgeton, NJ.  Both treatment facilities are now producing safer drinking water since the installation of the Z-88® Radium Removal treatment systems in 2009 and 2010.

  10. Iron, and Manganese Arsenic Pilot Study In The Golden State
    10/1/2018

    This report summarizes results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to demonstrate the effectiveness of water treatment products that employ oxidation and filtration to remove iron, manganese and arsenic to levels well below MCL’s. Operating data collected during the study will be used to confirm the design of fullscale facilities.
