• Benefits Of Off-Line Calibration Of pH And ORP Meters
    Benefits Of Off-Line Calibration Of pH And ORP Meters

    One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.

  • Instrument Resiliency For Tough Times
    Instrument Resiliency For Tough Times

    Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

    On-Site Disinfection Generation Enables City To Provide High Quality Water For Industrial Food Processing Customers

    The city of Buhl, Idaho, obtains all of its drinking water from groundwater sources through multiple wells. Prior to 2009, the city did not treat the groundwater but only added chlorine in the form of bulk 12.5% sodium hypochlorite to provide a disinfectant residual. A combination of factors including: changes in EPA and state DEQ regulatory requirements, growth of the residential population and growth of the industrial food processing customers forced the City to build a new water treatment plant to provide filtration to address the naturally occurring arsenic present in the groundwater.

  • 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.

    The Upper Trinity Regional Water District (UTRWD) is a conservation district created by the State of Texas in 1989 to provide water, wastewater, solid waste and storm water services to numerous towns and cities approximately 50 miles northwest of Dallas. In 2010, the UTRWD installed three 2,000 pound per day (PPD) chlorine equivalent Microclor® OSHG systems. The systems continue to provide UTRWD with a reliable supply of hypochlorite for disinfection in a manner that is less expensive and less risky than gas chlorine or liquid bulk hypochlorite delivered via truck or rail through such a heavily populated area.

  • How To Avoid System Downtime When Installing Flow Meters
    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.

    The key to high rate clarifiers such as inclined plate settlers is flow distribution says Tom Grubb, Regional Manager with Meurer Research. “Each inclined plate is like a miniature little sedimentation basin,” Grubb told Water Online in a recent Water Talk interview at AWWA’s ACE 2018. “To get good effluent quality, it’s critical that you have the same flow to each plate.”

  • 5 Steps To Prepare The Next Generation Of Water Workers
    5 Steps To Prepare The Next Generation Of Water Workers

    Much like investing in water infrastructure, the country often overlooks the pressing need to invest in a skilled workforce to manage these systems. Nearly 1.7 million “water workers”construct, operate, and maintain water systems found in every region, whether employed in utilities, engineering firms, or other industries. And many water workers are in short supply due to a wave of retirements and a lack of younger talent, even though they earn more competitive wages, tend to only need a high school diploma or less, and develop valuable skillsets over time.

  • Unleashing Smart SCADA
    Unleashing Smart SCADA

    When it comes to the future of utility management, every arrow points toward greater adoption of 'smart' systems. Supervisory control and data acquisition (SCADA) is smart, in a sense, but the mere existence of a SCADA system at your facility won't maximize efficiency and optimization. The capabilities and opportunities available to utilities through data and analytics are going largely untapped, according to two experts who joined Water Online for Water Talk, but a new initiative could help unlock its ever-growing potential.

  • Pushing The Needle For Progress, Reducing Water-Utility Air Emissions
    Pushing The Needle For Progress, Reducing Water-Utility Air Emissions

    Utilities are obsessed with taking contaminants out of water, but what about contaminants that are emitted into the atmosphere? While it's not their job to remove such pollutants, water utilities can help achieve cleaner air by not being part of the problem. It's an effort that may not be top of mind, but perhaps it should get more consideration; after all, water utilities are stewards of the environment — a badge of honor — and care for the environment most certainly includes the air we breathe.
