Drinking Water Treatment Case Studies and White Papers

  1. Flow Data Red Flags: When To Act
    12/20/2017

    Accurate flow measurement is critical to most water and wastewater processes. Red flags may pop up to indicate meter problems, but which ones should lead you to act — and when? The answer depends on the type of meter, what it is used for, and whether the readings are local or remote.

  2. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  3. Why A Little Knowledge About Sensors Can Be A Dangerous Thing
    6/4/2014

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  4. Natural Gas Fractionation Process Facilities Rely On Flow Switch For Relief Valve Leak Monitoring
    12/2/2017

    A company with multiple natural gas liquid (NGL) fractionation process facilities located in the Southeastern U.S became concerned about a series of missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief valves. The company wanted a highly reliable flow instrument solution that would detect a real event and avoid the lost productivity of nuisance alarms.

  5. Lessons Learned From Flint
    7/31/2016

    We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

  6. 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.

  7. Full Scale Installation: Village Of Bartlett, Illinois
    8/13/2012

    Located 35 miles northwest of Chicago, current population approximately 36,000. Average radium levels approximately 9 pCi/L. No other treatment, only the addition of chlorine and polyphosphate.

  8. NE Alabama Water District Case Study
    12/22/2011
    Northeast Alabama Water District (NEAW) services 15,200 connections within 2,052 square miles, resulting in a very large distribution area.
  9. Niederzeuzheim WWTP Case Study
    12/22/2011
    The villages of Oberzeuzheim and Niederzeuzheim, Germany are served by the Niederzeuzheim wastewater treatment plant. The plant was originally designed as a nitrification facility for a population of approximately 3,000.
  10. United Water Solves Big Data Problem With Siemens Magnetic Flow Meter Technology
    11/15/2016

    United Water, a division of the global conglomerate Suez Environement, operates regulated water systems in eight states, and provides contract services to over five million people.
