Wastewater Case Studies and Whitepapers

  1. Pure Oxygen Injection Into A Pipeline 9/15/2018

    The Hagerstown Wastewater Treatment Plant in Maryland incorporated several plant modifications, one of which was the conversion of their disinfection process from the use of ozone to UV.

  2. Meet Stringent Phosphorus Limits Under A Wide Range Of Conditions With The CoMag System 4/27/2016

    The Village of Waterbury Wastewater Treatment Plant (WWTP) is located on the Winooski River floodplain, which poses challenges from significant flooding during the spring runoff and storm seasons to strong algal blooms in late spring.

  3. EPA Researchers Inform Public Health Officials In Ohio On Variants Of COVID-19 Virus Through Wastewater Monitoring And Sequencing 11/2/2021

    Early in the pandemic, researchers at EPA’s laboratory in Cincinnati began looking for evidence of SARS-CoV-2 in municipal wastewater. Wastewater can contain indicators of COVID-19 infection in a community and this data can help inform public health decisions. For example, wastewater monitoring can help health officials know which communities need more access to testing, or  predict when infection waves might be present in a community, often before anyone shows symptoms of the disease.

  4. Aerzen Delta Hybrid Direct Drive: A Game Changer In Blower Technology 12/7/2025

    Aerzen’s Direct Drive Delta Hybrid blower boosts aeration efficiency with an optimized rotor profile, belt-free drive, improved cooling, and expanded turndown—cutting energy costs and simplifying long-term maintenance.

  5. U.S. Pipe Supplies Nearly 24 miles Of Pipe To Support Clean Water Efforts In Waukesha, WI 1/30/2026

    U.S. Pipe supplies 34 miles of 30-inch ductile iron pipe for Waukesha’s Lake Michigan water project, delivering reliable, high-pressure infrastructure for generations of residents.

  6. Next-Generation Solutions To Stormwater And Personnel Challenges 7/12/2021

    In an industry beleaguered by workforce retirements, costly consent decrees, and climate-induced heavy rainfall events, fresh perspectives and ingenuity are high-profile needs. Fortunately, the U.S. EPA’s  Campus RainWorks Challenge is designed to deliver exactly those benefits from the next generation of stormwater specialists. Here’s how current utilities, municipal planners, and consulting-engineer practices all stand to benefit.

  7. Ensuring Healthy Aquaculture: The Role Of Water Quality Monitoring 4/3/2025

    Real-time monitoring with fluorometers and turbidity sensors ensures optimal water quality in aquaculture, enhancing fish health, preventing disease, and promoting sustainable seafood production.​

  8. Aqua TruDense™ Provides Additional Capacity, Improves Settling, And Achieves Enhanced Nutrient Removal 9/4/2025

    A densified sludge process can improve wastewater treatment by promoting larger, denser sludge particles. This enhances settling, improves nutrient removal, and increases treatment capacity.

  9. Beyond The Concrete: How Packaged Headworks Solve Modern Wastewater Challenges 9/17/2025

    Packaged headworks systems provide flexible, high-quality screening for wastewater applications, offering fast installation, modular design, and low maintenance—ideal for temporary projects, small facilities, or specialized industrial sites.

  10. 'Smart Water' Benefits Without 'Big Data' Intimidation 3/31/2020

    For water treatment plants (WTPs) and wastewater treatment plants (WWTPs) pressured to do more with their data despite being pinched by a tight budget and a need to retrain employees, a new strategy can make all the difference. Here is how one such approach makes ‘smart water’ analytics less intimidating and how it has helped one utility make more cost-effective decisions while saving precious time and money.
