Drinking Water Measurement

  1. Is There A Correlation Between ATP And Other Traditional Microbiological Methods?
    12/7/2017

    Perhaps the most common question that we’re asked is how our ATP tests correlate with traditional microbiological methods.  Unsurprisingly, when people are used to getting their information in a certain way, they naturally want to know how a new method will stack up against it.  However, the mechanisms of culture-based techniques and ATP analyses are completely different, and in many ways, so are the results they produce. 

  2. Point Versus Continuous Level Measuring Technologies

    While point level measuring approaches are regarded as simple and user friendly, they lack the capabilities of more sophisticated continuous measuring instruments.

  3. Eaton Expands Online Training With New Online Commissioner Classes
    11/6/2017

    To help customers use variable frequency drives (VFDs) to enhance safety and reliability, Eaton is offering eLearning courses for VFD technology to support product, installation and commissioning and service knowledge. The robust online training program helps electrical distributors, contractors and industrial customers optimize the performance of VFDs.

  4. How To Clean And Handle pH Sensors
    10/31/2017

    For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

  5. The Energy Footprint Of Drinking Water
    10/26/2017

    Drinking water and wastewater systems are generally the largest energy consumers for municipal governments. However, there is little published information available on the exact energy usage for specific systems.

  6. Do You Really Want Manual Calibration?
    9/29/2017

    Many of us who have been around the water industry for a while can recall the days of manually calibrating online analyzers.  The arsenal would include:  a cart of tools, calibration standard, “calibrators”, and “zero sources”.  These tools would only be used a few times a year, if that.  Although the calibration of water analysis instruments should be performed on a monthly basis, most operators would admit to only calibrating them once or twice a year. 

  7. What's Faulty — Your Treatment Or Your Testing?
    9/29/2017

    The primary reason for laboratory testing at a water or wastewater plant is to determine if the facilities are meeting regulatory limits. Both proper operation and accurate testing are of utmost importance to ensure compliance. However, regulators and operators must consider limitations of the test methodology, as they may affect analysis results. The last thing any plant manager wants is unwarranted problems as a result of faulty analysis.

  8. Are Test Strips Still Relevant For Water Analysis?
    9/26/2017

    Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?

  9. Bulk Emergency Chlorine Vapor Scrubber System Restored For Oklahoma City
    9/19/2017

    As a bulk emergency chlorine vapor scrubber system approached the end of its anticipated 20-year useful life, the city engaged Integrity Municipal Systems, LLC (IMS) inspected the equipment and proposed a system refurbishment plan that would ensure proper system performance and safe storage of the 30,000 gallons of corrosive caustic soda contained within it.

  10. What Lies Within… What You Need To Know About Hardness Monitoring
    9/12/2017

    Water hardness can wreak havoc on your boilers, creating holes in tubes, eating away at the walls. To keep the hardness at bay, you’re going to need to monitor the levels of calcium and magnesium seeping into your system.  There are things you need to know to ensure that you are doing this properly. First, use an automated system to increase reaction time to hardness. Next, monitor the softeners; they are critical in keeping the system functioning. Last, learn the temperament of your individual boiler; no two are alike.
