Drinking Water Treatment Case Studies and White Papers

  1. Membrane Treatment Of Groundwater
    4/2/2015

    The groundwater that a southern Louisiana water utility supplies to local residents has traditionally carried a high amount of organic material and color. In the past, the organics were oxidized and broken down by chlorination, but this practice had gone out of favor due to production of disinfection by-products (DBPs) such as Trihalomethanes (THMs) and Haloacidic Acids (HAAs).

  2. TotalCare Condition Audit Results In Energy Savings Of 80% And Improved Controls
    5/1/2017

    Xylem TotalCare Condition Audit, an inspection and recommendation program that helps plant operators find ways to lower maintenance costs by identifying inefficiencies in the operation of water and wastewater equipment, was elected to audit the American Canyon Wastewater Treatment Plant (WWTP) in California.

  3. A New Breakthrough In Flow Metering
    3/26/2014

    Municipalities that are looking to accurately measure their water flow rates often fall into one of three categories. By Mark Gimson

  4. Case Study: Aquatech Supplies One Of Most India's Largest Tertiary Treated Sewage Recycle Plants
    2/22/2011
    The water supply body in Mumbai having increased water charges to almost a dollar per cubic meter of water in year 1998-99, and the huge water quantities demanded for processing of fertilizers, RCF required a solution wherein it could effectively recycle the sewage water to be made available by the Municipal body. By Aquatech International Corporation
  5. Water Reuse Strategies: Steel Industry Case Studies
    3/18/2011
    Successful reuse of water back into industrial water applications requires a comprehensive understanding of process design, water chemistry, membrane systems, chemical treatment, instrumentation and control. By David Christophersen, Technical Support Manager, Crown Solutions
  6. 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.

  7. Shanghai Investigation Sets BIM Standard On Ningbo Yongxin’s Urban Flood Control Project
    11/1/2016

    In response to the devastation from a 2013 typhoon that caused the Yongxin and Yongjiang rivers in Ningbo, China to overflow, Ningbo Raw Water Group Ltd. commissioned the detailed design and construction of a CNY 178 million emergency sluice pump. The pump would provide flood control measures and mitigate future flood losses to improve urban infrastructure services within the Zhejiang province. To avoid the risk of additional flooding from another typhoon, the Raw Water Group required the urban flood control project to be delivered in a demanding eight-month schedule—a process that would ordinarily take 24 months to complete.

  8. Pre-Filtration Is Essential To Protect Your Membranes
    12/15/2016

    Any Reverse Osmosis System is only as good as the Pre-filtration System protecting it.  Pre-filtration is no place to scrimp when it comes to sizing, quality, efficiency and performance. 

  9. Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber
    4/16/2014

    This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.
