Drinking Water Analysis Resources

  1. Monitoring The Future With The Latest Sensor Tech 9/8/2015

    Doctors have their stethoscopes, plumbers have their wrenches, and accountants have their calculators. More often than we would care to admit, professionals are only as good as their tools. For water utilities, staying on top of water quality means taking advantage of the cutting edge in sensor technologies.

  2. The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It's The Pressure, Not The Concentration) 8/5/2015

    A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

  3. 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.

  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. Chloramination Monitoring And Control 7/15/2015

    Since the EPA has established that, together with free chlorine, monochloramine is a primary disinfectant, it has been possible to implement the process more intensively. Water that is treated with monochloramine has, depending on the source of the water, fewer problems concerning taste and odor than water treated with free chlorine. In addition, the chemically more stable monochloramine remains longer in the water, thus allowing a long-term disinfecting effect.

  6. Chicago Suburb Ensures Highest Water Quality Year-Round, Saves On Labor And Reagents With New Chlorine Analyzers 5/18/2015

    For the Village of Lombard’s Water Division, consistently delivering high-quality tap water to the community’s nearly 44,000 residents and the businesses serving them was once quite a juggling act: constantly fixing old, temperamental analyzers; feeding reagents into the old analyzers; and staying ahead of callers complaining about “musty” water tastes and odors. Not today.

  7. Portable Parallel Analysis: Streamlining Distribution System Water Testing 3/6/2015

    A Water Quality Specialist used the Hach SL1000 Parallel Portable Analyzer (PPA) to test 6 parameters simultaneously – all within about 8 minutes.  Previously, the procedure took 20 minutes just for one parameter.

  8. Optimize Energy And Resource Usage 2/17/2015

    Through the implementation of a WAGES (Water, Air, Gas, Electricity and Steam) monitoring solution, a brewery was able to optimize energy and resource usage while boosting capacity to meet the demands of U.S. customers. Water usage costs were reduced by 28%; the brewery’s carbon footprint was reduced creating a savings of $2 million/year from CO2 recovery; compressed air usage was reduced by 15%; and fuel oil costs were reduced by $34,000.

  9. Drinking Water Protection — Are We Doing It Right? 12/17/2014

    “We have analytical instruments that can see things in astronomically small numbers, but are we looking for the right things?”

  10. Do-It-Yourself Cryptosporidium Detection 10/6/2014

    Learn how to construct a simple and inexpensive tool for detecting Cryptosporidium in your watershed — and why it’s important.
