Drinking Water Measurement White Papers and Case Studies

  1. 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.

  2. How To Avoid System Downtime When Installing Flow Meters
    7/11/2018

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  3. Improving Flow Measurement Accuracy With Flow Conditioners
    12/1/2017

    When looking for a way to reduce plant operating costs, one of the potentially simplest and often least expensive solutions is to measure liquid and gas flow more accurately. Plant upgrade projects that focus on the continuous improvement of flow measurement and control can trim overall production costs by eliminating waste and reducing maintenance costs.

  4. Ultrasonic Metering For Small Water Meter Applications
    9/19/2013

    For many years, ultrasonic metering has been utilized for large scale liquid and gas measurement. However, it is a relatively new technology for small meter applications — particularly those designed for potable water.

  5. Accurately Measuring LNG Tanker Boil-Off Gas For Process Efficiency And Environmental Compliance
    2/1/2016

    With the recent growth in demand and production of liquefied natural gas (LNG), there has been an increase in trade and the need to transport it globally via LNG tanker ships.

  6. Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
    7/20/2015

    Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the vari­able frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sen­sors and analyzers from Emerson.

  7. New AMR System Improves Efficiency, Conservation, Customer Service And Revenue For Coeur d’Alene
    9/20/2013

    The City of Coeur d’Alene, Idaho, had been using a drive-by Automatic Meter Reading (AMR) system to read all of its meters since 2010, but according to Rob Stark, utility supervisor for the City of Coeur d’Alene Water Department, it wasn’t realizing the full benefits with its existing system.

  8. A New Breakthrough In Flow Metering

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

  9. Turbidity’s Role In EPA Compliance
    6/11/2018

    Turbidity measurement is both a nebulous, oft-misunderstood concept and the master link in a chain of events affecting U.S. EPA drinking water compliance. It can influence, or be influenced by, almost every other link in a water treatment process. Here is a quick overview of turbidity’s relationship to drinking water compliance standards and some tips for keeping a water treatment process in balance.

  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.
