  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy
    Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results
    Water Monitoring's Triple Threat: Bad Habits, Bad Readings, Bad Results

    When water and wastewater plant operators can’t get accurate flow measurements or analytical readings — or lack confidence in their instruments’ readings — it creates challenges with the process. When substandard water goes to homes and causes a boil order, or discharge pollutes a lake or reservoir, the resulting bad press, fines, and potential lawsuits erode public confidence. Avoiding these kinds of problems is rooted in good preventive maintenance habits.

  • Sounding The Alarm On Silent Noncompliance
    Sounding The Alarm On Silent Noncompliance

    Water and wastewater utility operators work diligently to operate within strict guidelines, ensuring their facilities are producing the best drinking water and highest quality effluent possible. Despite all their efforts, however, it can be easy to fall outside of regulatory compliance without even being aware. The key to avoiding problems like these is to understand how silent noncompliance can happen and knowing when to raise a red flag.

    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).

    What Can 2nd Generation ATP Do For An Operator Or Field Technician?

    It’s important to start with the fact that this is not a regulatory test. This technology won’t replace any required compliance tests and the results are not reportable, which is actually a great benefit to our users. While regulatory testing is important, compliant does not necessarily mean clean.

  • Identifying The Best Lead Sampling Techniques To Protect Public Health
    Identifying The Best Lead Sampling Techniques To Protect Public Health

    If lead is found in drinking water, it is important to identify where it is coming from within the water system — that means taking samples at every stage, from the distribution system all the way to the plumbing system inside the home, also known as premise plumbing.

The Role Of Digitalization In Today's Treatment Plants The Role Of Digitalization In Today's Treatment Plants

The best systems are ones that are not just effective by design; importantly, they are employed to optimal effect. When it comes to treatment plant instrumentation and automation, it's essential that the volumes of data collected throughout the treatment process are easily understood and acted upon. In this video, Jack Roushey, Marketing Manager for the Flow Division of Siemens Process Instrumentation, talks about how Siemens addresses these challenges through their portfolio of process measurement and analytics systems. He discusses the advantages of digitalization, including digital twin technology, and how smart instruments can be leveraged to solve some of the industry's highest-level concerns, such as water quality and resiliency, while making it more simple than ever for operators.
