Drinking Water Measurement White Papers and Case Studies

  1. 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.

  2. Ozone Demand Testing = Disinfection Project Success
    7/19/2013

    Water and wastewater facilities are increasingly looking to ozone disinfection. A strong and indiscriminant oxidant, ozone can effectively address treatment issues with THMs and DBPs in the disinfection process. Ozone disinfection is also a proactive step toward addressing future rules on endocrine disrupting compounds (EDCs) and other trace organics at both water and wastewater plants. While there are many aspects to ozone disinfection system design, the single most important factor in project success is a thorough understanding of your facility’s ozone demand profile. This article provides an outline of the key factors to make your ozone demand test -and ozone project- a success. By Thoram Charanda and Louis LeBrun

  3. Beating Your Water Bill: How Fast, Accurate Water Usage Data Improves Customer Relations
    11/5/2014

    Municipality arrives before the water bill to alert customers of unusual spikes in usage.

  4. Turbiwell Comparision Report Before And After Upgrade
    7/29/2015

    Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters. 

  5. Turbidity 101: What It Is, And Why It Is So Important
    6/12/2018

    Turbidity, a measure of the cloudiness or haziness of a fluid, was originally intended as a qualitative measure of the aesthetics of drinking water. It is not a measure of actual particles in the water; it measures how much those particles affect light being transmitted through the water, or how that light reflects off particles in the water. Today’s turbidity designs and methods have been regimented in an attempt to bring quantitative consistency to the measurement for both aesthetic and pathogenic qualities of drinking water.

  6. Lightning Fast Response Prevents Extended Down Time
    7/29/2015

    The City of Gordon Texas’s drinking water facility was struck by lightning. Thinking long term, and desiring the latest technology available, the City took this opportunity to upgrade their on-line instrumentation with a range of new continuous monitoring on-line instruments including chlorine analyzers, pH monitoring, temperature monitoring, and turbidity monitoring.

  7. Online TOC Analysis In The Drinking Water Treatment Process
    4/22/2015

    In 1974 the Congress of the United States passed Public Law 93-523; the Safe Drinking Water Act (SDWA) to protect public health by regulating the nation’s drinking water supply and protecting sources of drinking water. The SDWA first went into effect on June 24, 1977 and has been amended multiple times.

  8. Mass Or Volume? A Weight Off The Bottom Line
    1/12/2015

    Confusion often arises over the difference between mass and volume flow measurement and when a particular measurement should be applied.

  9. U Of I Urbana-Champaign Implements Remote Monitoring System
    8/23/2017

    The Utility Distribution team at the University of Illinois at Urbana-Champaign manage the water system which serves the entire campus. The University purchases water from Illinois American Water which is distributed across the campus for uses as diverse as chemistry labs, agricultural research, and competitive swimming complexes.
