Drinking Water Treatment Case Studies and White Papers

  1. 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.

  2. Nitrification In Monochloramine-Treated Water
    5/9/2018

    A water utility in the Midwest USA uses Monochloramine treatment in their two surface water treatment plants to disinfect raw water and establish residual disinfectant prior to discharge to their distribution system. 

  3. Remote Diagnostics Will Reduce Service Costs And Increase Uptime Of Filtration Systems
    2/5/2015

    Filtration OEMs can use built-in device diagnostics to monitor and maintain automation component performance.

  4. WSSC Achieves Over 60% Reduction In Hydraulic Plan Review for Water And Wastewater Systems
    12/1/2016

    Washington Suburban Sanitary Commission (WSSC) Development Services Group reviews hydraulic plans for approximately 160 proposed development plans per year. This includes water and sewer system extensions as well as approximately 172 small-site utility plans (commercial private systems) that connect to the existing water and sewer network in two large Maryland counties.

  5. How To Keep Consistent Chlorine Residuals In Small Storage Tank Systems
    6/26/2018

    Chemicals used for disinfection react with various contaminants in water and degrade over time, resulting in a loss of disinfection residual.   The loss of disinfectant residuals can set up conditions for serious bacterial growth, as well as increased levels of disinfection byproducts.  

  6. Multi-Barrier Disinfection Strategy - New York City (Case Study)
    1/15/2014

    New York City is home to more than 8 million people, making it the most populous city in the United States. The majority of New York's drinking water is supplied by the Catskill/Delaware watershed, located approximately 100 miles outside the city. Historically, NYC has not filtered the water from this system, nor did they require any additional barriers to microbial contaminants due to the pristine nature of the watershed.

  7. 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.

  8. Portable Parallel Analysis: Streamlining Distribution System Water Testing
    3/6/2015

    A Water Quality Specialist used the Hach SL1000 Parallel Portable Analyzer (PPA) to test 6 parameters simultaneously – all within about 8 minutes.  Previously, the procedure took 20 minutes just for one parameter.

  9. 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.

  10. Ozone Vent Gas For Aeration At Wastewater Plant Expansion In China
    6/17/2016

    The Jimo, China, municipal wastewater plant was originally designed to treat a combination of municipal and textile wastewater (120,000 m3/d) with Class IB effluent limits for BOD, COD, ESS, TN, NH3-N and TP.
