    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.

    How To Avoid System Downtime When Installing Flow Meters

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  • Knowledge Transfer For Water’s Better Informed Future

    Water industry managers are caught in a squeeze. On one hand, they need to capture institutional knowledge from long-term baby boomer employees before they retire. At the same time, they need to manage current operations optimally and attract and train next-generation replacements. Here is how advanced analytics solutions are making it easier to achieve all those goals while improving business outcomes.

  • BYOD: Are The Barriers Of Patients Using Their Own Mobile Devices, Myth Or Reality?
    BYOD: Are The Barriers Of Patients Using Their Own Mobile Devices, Myth Or Reality?

    BYOD is a topic often discussed in the context of electronic clinical outcome assessments (eCOA) but there has been limited use of BYOD in regulatory studies to date and common perception is that delay in uptake is due to measurement equivalence and technical and practical issues. In order to identify and assess the perceived barriers and challenges with the use of BYOD for eCOA, ICON in association with Medidata and mProve Health conducted a recent survey. Read how commonly-cited concerns around the use of patients’ own devices are not as great a deterrent to adoption as originally thought.

  • 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.

  • The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried?
    The Microbes Have Us Outnumbered 20 To 1: Should We Be Worried?

    A lot has changed over the past 15 years. Back in the early 2000s, many utilities weren’t interested in understanding what was in their water beyond the contaminant and disinfection byproduct levels they were regulated to comply with. But as Pat Whalen, President and CEO of LuminUltra, explains in this ACE 2018 Water Talk interview, a steady stream of ongoing education and the modern data storage and analytics that cloud computing provides, has developed some rabid fans eager to explore the microbiology of their water systems.

  • Linking Technologies Key To A Successful Potable Reuse Project

    Potable reuse offers a massive opportunity to recover water from the wastewater process, but projects face a variety of barriers to getting off the ground. Most successful early adopters engaged early with their constituents and implemented smaller-scale demonstration projects that were accessible to the public to prove the technology and process.

  • What Did Rural America Do To Deserve This?

    By now, just about everyone in the U.S. has heard about Flint, Michigan’s water woes. Despite the many issues raised by that incident, urban water systems are not the sole reason the 2017 Report Card from the American Society of Civil Engineers gives the U.S. drinking water infrastructure an overall “D” grade. Hidden within that disheartening rating are the harsh realities faced by rural water systems.

  • Achieving Level Pressure At Challenging Points In Distribution Systems
    Achieving Level Pressure At Challenging Points In Distribution Systems

    When drinking water leaves a treatment plant through giant pipes, with the help of huge pumps, the pressure can exceed 200 psi. The high pressure is a necessity because water must travel a long distance in some cases. Water towers scattered throughout the distribution system aid in the process so it can reach all utility customers. The problem is that not all distribution points in a water system are created equal.

Here are insights on how to forestall becoming the next city to make national headlines related to harmful algal blooms.

  • Peaking Factors And Hydraulics In Wastewater Screen Sizing

    Dealing with fine particulate matter, nutrients, and pathogens is essential for wastewater treatment plants (WWTPs) striving to meet Clean Water Act (CWA) effluent standards.

  • 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.

    As with so many other drinking water treatment processes, corrosion control demands a delicate balance among multiple factors. From the water-purifying chlorine that increases corrosion risk, to alternative strategies that reduce corrosion — using either elevated pH or phosphates — keeping corrosion under control requires sound strategy and reliable execution. Here are several approaches to addressing those conditions, along with options for better, more effective corrosion control.
