Contaminant Removal Case Studies and White Papers

  1. Ozone-Biologically Active Filtration For Potable Reuse In California's Inland Communities: Benefits And Barriers
    5/17/2016

    California’s inland communities have been hit hard by four years of drought, lower groundwater levels, and reduced allocations from the State Water Project.

  2. Need More Water? Think Ozone-BAC For 'One Water' Resolution
    8/25/2017

    If you thought reverse osmosis was the one and only choice for potable water reuse, think again. Ozonation followed by biological activated carbon (ozone-BAC) is more suited to inland communities and may be better at removing chemicals of emerging concern (CECs).

  3. Moving Forward For America's Drinking Water
    4/28/2016

    Our nation’s record of progress in advancing public health under the Safe Drinking Water Act is significant.

  4. Ozone To Enhance Removal Of Iron And Manganese And Reduction Of THM
    4/27/2017

    The U.S. EPA's promulgation of the Stage 2 Disinfection By-Products Rule required  the Public Works Department of Danvers, MA, to establish a Two-Phase upgrade of the plant’s treatment process in order to comply.

  5. Indirect Potable Reuse With UV-Oxidation - Big Spring, Texas (Case Study)
    12/12/2016

    In an effort to reduce reliance on dwindling surface and groundwater supplies in Texas, the Colorado River Municipal Water District (CRMWD) constructed a new Raw Water Production Facility (RWPF) in Big Spring. Big Spring is a 27,000-member community located in West Texas approximately 300 miles west of Dallas. This RWPF treats secondary wastewater to a standard that allows it to be re-introduced directly into the raw water supply for the water treatment plants of Big Spring, Odessa, and other communities in the region.

  6. City Of Austin, Texas Installs A Total of 4,500 Pounds‐Per‐Day Of On‐ Site Hypochlorite Capacity Using the Microclor® OSHG System
    4/6/2017

    With 100 years of service history, Austin Water has seen enormous change in its 540 square miles of service area. Planning for the next 100 years has city and utility planners considering a diversity of sources, system resilience, and sustainability while being mindful of conservation goals. In the city’s newest water treatment plant, WTP4, Austin Water was able to combine those planning elements into a state‐of‐the‐art treatment plant. The plant, which is located on Lake Travis, is capable of treating 50 million gallons a day (MGD) with the ability to expand to 300 MGD.

  7. Largest Ozone Facility In North America Meets Regulatory Requirements And Remediates Taste & Odor Problems
    4/27/2017

    The North Texas Metropolitan Water District began working to add ozone to its four interconnected water treatment facilities which operate as the Wylie Water Treatment Plant (WTP).

  8. Mitigating Environmental Impact Of Gold Mine’s Wastewater Through Ozone Oxidation And Aquifer Re-injection
    4/27/2017

    Installing and operating an ozone oxidation system for wastewater remediation at a gold mine located in a remote region of Alaska is full of challenges.

  9. Science Guides Public Health Protection For Drinking Water
    5/19/2016

    As a country, we’ve come a long way toward providing clean air, water, and land — essential resources that support healthy, productive lives. But we have more work to do to make sure that every American has access to safe drinking water.

  10. City Of Springfield, MO, Upgrades Disinfection System From Gas Chlorine To On‐Site Sodium Hypochlorite Generation
    8/15/2016

    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.
