Wastewater Contaminant Removal White Papers & Case Studies

  1. Protecting Water Resources: A Multifaceted Approach
    11/7/2017

    As the cost of and demand for potable water increases, engineers, planners, and utilities need reliable, innovative methods for protecting this valuable resource. Cost-effective and environmentally sustainable wastewater collection and treatment systems are vital components in the water cycle and therefore require careful analysis. While there is no single solution for every site or community, traditional ‘big-pipe’ systems are rarely appropriate in sensitive environments; fortunately, today there are more options than ever to consider.

  2. MABR-based Wastewater Treatment Plant Built From The Ground Up In The Caribbean
    10/26/2017

    The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality. Its existing plant was old and did not meet regulation nor industry standards. Fluence, together with its partner SD&C Inc., built an MABR-based wastewater treatment plant from the ground up, utilizing whatever existing pieces of equipment could be used from the old plant.

  3. Treatment Plant Upgrade Includes Conversion To On-Site Sodium Hypochlorite Generation To Ease Operations And Increase Safety

    Fairmont, Minnesota, known as the City of Lakes, is located in Martin County in southern Minnesota. The city’s water treatment plant serves a mix of customers including approximately 3,900 residential taps, 500 commercial and 17 industrial customers. Looking to the future, Fairmont city leaders began to investigate upgrading the city’s water treatment plant in 2010. The existing plant had been in operation for well over 70 years and relied on gas chlorine for disinfection.

  4. Ecomuseum Zoo: High Efficiency Filtration Reduces Turbidity & Maintenance Costs
    9/12/2017

    ​The Ecomuseum Zoo is home to the most impressive ambassadors of Quebec’s wildlife. All residents of the Ecomuseum Zoo are there for a special reason: orphaned, injured or born under professional human care, each of them could not return to the wild. Hence, they have found a forever home at the zoo.

  5. Automated Residual Boosting System Improves Chloramine Levels, Eliminates Nitrification In 400,000-gal Tank
    7/31/2017

    Like many municipalities in urban and suburban areas, San Bruno’s source water comes both from its own groundwater supply and through a purchase agreement with a major water utility — in this case, San Francisco Public Utilities Commission (SFPUC). And, like many municipalities in California, SFPUC, along with San Bruno, switched from free chlorine to chloramines in 2003 largely to reduce disinfection by-products.

  6. Granular Activated Carbon: A Long-Term Solution For Meeting DPB Compliance
    7/31/2017

    When the Cobb County-Marietta Water Authority (CCMWA) anticipated the need to upgrade the Hugh A. Wyckoff water treatment plant, they turned to granular activated carbon (GAC) technology after vetting several alternatives. The plant, a wholesaler in a two-plant system, processes up to 72 million gallons per day and serves about 350,000 people. Comprising of Wyckoff and the James E. Quarles treatment plant, CCMWA is the second largest water provider in Georgia.

  7. Mapping And Identifying The Source Of Water Quality Issues
    6/28/2017

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  8. Has The Ideal Biocarrier Finally Been Developed?
    6/1/2017

    In order to improve the efficiency of biofilm technologies, a high-performance biocarrier has been developed, based on requests for ideal carrier characteristics.

  9. Filter Technology Saves Colorado Plant 50,000 GPD
    5/16/2017

    Combined with the installation of the new filter media and wash troughs, this particular type of underdrain and media retainer brought the water treatment plant’s operations up to speed.

  10. Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant
    5/15/2017

    In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.
