Drinking Water Measurement White Papers and Case Studies

  1. Clari-DAF® System Provides Effective TOC Removal For Cambridge WTP
    3/9/2015

    To ensure treated water complied with the most stringent drinking water standards, including the Environmental Protection Agency (EPA) Stage 2 Disinfectants and Disinfection Byproducts Rule (State 2 DBPR), the City of Cambridge, MA, WTP decided to implement a robust multibarrier treatment solution.

  2. 3 Tips To Optimize Cooling Water Management For Lower Plant Operating Costs
    6/12/2015

    Evaporative cooling towers are key components in the effective operation of plants in the electric power, industrial process and manufacturing industries.

  3. Smart Antenna Technology Enhances AMI Network Reliability
    3/7/2016

    Advancements targeting the challenges related to a flooded meter pit environ­ment have occurred slowly over the years, with limited success.

  4. Chlorine vs. Chloramine: A Tale Of Two Chemistries
    4/17/2018

    In drinking water treatment’s ongoing battle between disinfection and disinfection byproducts (DBPs), most water utility customers are oblivious to the process. One thing they do notice, however, is when their water smells or tastes bad. Here are some insights that can help water treatment plant (WTP) operators deal with their internal concerns about DBPs and residual chlorine or ammonia levels, as well as their external concerns about customer perceptions of water quality.

  5. Singer Valve Improves Aussie Water Supply
    11/20/2012

    Without the right solution, aging water pipes, overflowing tanks and noisy valves can become chronic issues to a water retailer’s supply infrastructure.

  6. Smartphone App Delivers Reproducible And Precise pH Analysis
    11/8/2018

    Traditionally when it comes to analysis, there have been two ways to measure pH. The first is the inexpensive method of using test strips, which requires little time or training. The second requires the use of a pH electrode or probe and because it requires more training, time, and equipment, is far more expensive. However, a hybrid application is now available that brings together the ease of use of test strips with technology to ensure preciseness.

  7. How Calibration Impacts Flow Meter Performance
    7/12/2018

    Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.

  8. 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

  9. In-Situ Calibration: Methods And Pitfalls Of Thermal Mass Flow Meter Sensor Field Validation
    5/1/2016

    Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.

  10. Technology Advancements Improving Real Time Spectral Analysis
    11/15/2012

    Real time spectrophotometers offer the immediate detection capability of a wide range of important and emerging contaminants of concern.
