  1. Why Modular MBRs Are Replacing Conventional Activated Sludge For Plant Expansions 7/6/2026

    When community growth and strict regulations demand wastewater plant expansions, traditional infrastructure often requires too much space and time. Discover how modular membrane bioreactors shrink footprints by up to 75%, accelerate deployment, and lower operational costs.

  2. 6 Pilot Testing Mistakes That Impact Full-Scale Success 7/6/2026

    Avoiding common pilot testing mistakes helps utilities improve technology selection, generate more reliable data, and increase confidence in full-scale treatment performance.

  3. Stop Asking How Much Biomass To Retain. Ask Which Biomass, And Where. 7/1/2026

    Wastewater process intensification has long centered on a single instinct: hold more biomass in the same tank. Whether the technology is integrated fixed-film activated sludge (IFAS), a moving bed biofilm reactor (MBBR), or something else, the working assumption is that more retained biomass means more treatment capacity.

  4. Why Industrial Water Treatment Is Never "Set And Forget" 6/30/2026

    Industrial wastewater treatment is never a static task. Fluctuating pH levels, production shifts, and variable organic loads mean that no two effluents behave identically, demanding continuous monitoring and active process discipline to maintain discharge compliance.

  5. The Enzyme Bottleneck: Why Conventional Lake Management Is Failing — And What The Science Says About Genuine Bio-Dredging 6/30/2026
    For decades, the dominant framework for assessing and managing lake health has been built around surface water measurements: chlorophyll-a, total phosphorus, water clarity, and the composite Trophic State Index derived from them. These metrics are familiar, standardized, and widely accepted. They are also, according to a growing body of peer-reviewed literature, measuring the wrong part of the lake.
  6. How Risk Management Can Build More Resilient Utilities 6/30/2026
    From rapidly evolving cyber threats and extreme weather patterns to regulatory pressures and emerging contaminants, modern water and wastewater utilities are facing an unprecedented era of growing risks. To navigate these challenges, forward-thinking organizations are adopting structured risk assessment frameworks that support long-term resilience rather than reactive emergency response.
  7. Retrofit Strategies For Ultrasonic Flow Technology In Industrial Applications 6/25/2026

    Successful ultrasonic flow meter retrofits depend on matching technology, process conditions, and installation requirements to improve accuracy, reliability, and operational efficiency.

  8. Rethinking The Role Of Grinders In Today's Collection Systems 6/22/2026

    Customized grinders help wastewater utilities manage wipes and difficult solids while protecting infrastructure, reducing maintenance requirements, and improving collection system reliability.

  9. How Water Infrastructure Can Drive Economic Growth 6/18/2026
    The U.S. water and wastewater industry is standing at an awkward crossroads. For years, technical capabilities, federal funding, and a shared sense of industry urgency have all co-existed in a critical mass. However, the rollout of major infrastructure projects remains sluggish.
  10. 5 Takeaways To Prepare For Hurricane Season And Build More Resilient Communities 6/18/2026
    Stronger storms are exposing the limits of outdated infrastructure. From upgrading capacity to building stronger partnerships, here are five key lessons utilities can apply now to prepare for hurricane season and keep critical water systems running under pressure.
