Drinking Water Measurement

  1. When Inches Count: Flow Metering In Constrained Spaces

    From offshore oil platforms that come with a hefty cost for every square foot to college campuses that rely on steam plants in cramped basements, flow metering is critical to many operations where space comes at a premium. The problem is that most flow metering technologies conflict with space limitations because of their substantial straight pipe run requirements. The good news is there is an alternative.

  2. Monitoring WTP Ozone Use With Maximum Cost-Efficiency

    The value of ozone as a disinfection agent is well understood in water treatment plants (WTPs). So too, is its cost. Getting maximum value from an ozone investment requires accurate measurement to assure proper disinfection levels without wasteful overuse of the precious gas. Here are multiple ways thermal dispersion mass flow meters deliver precise readings with lower installation and maintenance costs.

  3. Installing Granular Activated Carbon Today To Prevent Regulatory Issues In The Future

    In 2010, Shelby County Water Services (SCWS) was planning for the future. With new regulations on the horizon, SCWS determined that the Talladega/Shelby water treatment plant in Shelby County, AL, needed more effective removal of disinfection byproducts (DBPs). Specifically, the treatment plant needed help complying with the U.S. EPA’s new Stage 2 Disinfection Byproduct Rule (DBPR).

  4. Achieving Effective Microbiological Management In Distribution Systems

    Most distribution system water-quality problems can relate back to microorganisms growing as biofilms in the pipes. These biofilms can prompt chlorine residual degradation, corrosion, nitrification, THM formation, red or black water, and taste and odor problems as well as other issues. An effective microbiological control strategy combines the appropriate testing technologies and their use at optimal intervals.

  5. Thwarting Nitrification With A Proactive Approach

    A lack of real-time monitoring capabilities for treated water once it leaves the plant has many utilities scrambling to manage nitrification, which can appear abruptly and then be difficult to contain. Fortunately, advanced testing tools are available so water plant operators can take a proactive approach to the hazardous condition in their distribution systems.

  6. Balancing The Yin And Yang Of Water Pressure

    All the effort and expense required to produce high-quality water can be for naught if the distribution system cannot maintain appropriate pressure to deliver it efficiently, at a reliable flow rate. Simply pumping more pressure into the system is not the answer. Learn how new pressure monitoring options make it easier to track pressure in every zone to deliver customer satisfaction at peak energy efficiency.

  7. Comparing Benefits Of V-Cone® And Coriolis Meters

    Proper operation of water treatment processes depends on accurate flow measurements. Also, flow data is often required by regulatory agencies.

  8. Accurate Metering For Every Water Consumer’s Habits

    Utilities looking for greater billing efficiency and control over every drop of water consumed by their customers face a constant battle with non-revenue water loss, which can be compounded by different metering technologies and consumer behaviors. Using accurate, always-on, continuous-sampling meters to take full advantage of automated smart utility networks is a better way to improve decision-making and achieve accountability goals across any circumstances.

  9. Quantifying The Benefits Of High-Volume Meter Testing

    “I know that (blank) is good for me; I just haven’t gotten around to doing it yet!” Most of us can fill in that blank with any number of tasks — modifying diets, exercising, or monitoring commercial and industrial (C&I) water meter accuracy at our largest utility accounts. If that last item is still on your “to-do” list, here are several good reasons why you should do it and how to make it happen soon.

  10. Making Turbidity Readings Consistent, Reliable, And Compatible

    When water treatment plant (WTP) instrument readings impact regulatory compliance, any discrepancy between laboratory and inline instrument readings can be disconcerting. Fortunately, improved sensor technologies and Mobile Sensor Management capabilities can enhance operator confidence in managing the significance of those readings throughout WTP processes.
