Drinking Water Filtration Case Studies and White Papers

  1. Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow
    4/25/2017

    The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.

  2. Improving The Quality Of Tertiary Effluent For Indirect Potable Reuse With Geographic Constraints
    4/24/2017

    The Mazzei Sidestream Venturi Injection – Pipeline Flash Reactor System provides a feasible alternative for dissolution of ozone at the Clark County Water Reclamation District (CCWRD) in Las Vegas, because it allowed for flexibility in basin design to meet geographic site constraints.

  3. State-Of-Art Filters Triple Filter Run Times And Maximize Performance
    3/16/2017

    A plant manager in Colorado became frustrated by the consistently short filtration run-times and the large amount of water wasted by the four dual-cell bottom filters used to clean the region’s drinking water. Xylem’s Leopold Type XA underdrain with I.M.S 200 media retainer, new filter media (12” silica sand/18” anthracite), and wash troughs, emerged as the top choice.

  4. Dual Membrane Plant System Audit

    How do you know if you are in control of microorganisms in your dual membrane plant? See how one water treatment plant performed a system audit using ATP technology to confirm microbiological treatment efficacy through each stage of the process.

  5. Rapidly Pinpoint Biological Hotspots In Your Distribution System
    12/14/2016

    After reports of Naegleria fowleri amoeba being found in some Louisiana municipalities’ drinking water systems, regulators mandated that free chlorine residual be maintained at a minimum of 0.5 mg/L throughout distribution networks in the state. In September 2014, Thornton, Musso & Bellemin Inc. (Zachary, LA) conducted an extensive sanitary survey in a small municipality to establish baseline numbers and troubleshoot hotspots.

  6. Granular Activated Carbon Removes PFOA From Drinking Water
    12/7/2016

    In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.

  7. Better Water For Less Than Half The Cost
    11/4/2016

    When Anderson Regional Joint Water System (ARJWS) in South Carolina began experiencing a cyanobacteria (blue-green algae) bloom that was beyond its treatment plant’s ability to handle, they turned to the experts at Clemson University and an innovative, targeted, and cost-effective method of treatment to meet its customers’ expectations for taste and odor. Read the full case study to learn more.

  8. Global Pharmaceutical Company EnviQ Membrane Bioreactor (MBR)
    11/4/2016

    The Serum Institute is a global pharmaceutical company that is one of the world’s largest producers of vaccines. The Institute was planning an expansion to their manufacturing plant in Pune, India, that resulted in an additional water requirement for the plant’s needs.

  9. Mobile Membrane Systems Provide Emergency Response
    9/21/2016

    When emergencies inevitably arise, municipal operators need to be prepared to respond immediately to restore services in order to provide safe, reliable water to their customers. Take for example the City of Cisco, Texas.

  10. Mountain Regional Water District Deploys Next Generation On-Site Hypochlorite And Tank Mixing Technology To Meet Expanding Water Management Needs
    8/15/2016

    The Mountain Regional Water District is a Special Service District of the county that was established by the Summit County Commission in 2000 to regionalize water service by consolidating several public and private water companies.
