  1. How Regulatory Pressure Is Driving Innovation In Surface Water Facilities 3/23/2026

    What does it take to stay ahead of tightening drinking water standards? See how utilities are turning regulatory pressure into smarter infrastructure investment.

  2. Optimising Coagulation And Flocculation Systems In Surface Water Facilities 3/23/2026

    Coagulation and flocculation remain essential but increasingly sensitive processes, requiring flexible design and real-time optimisation to maintain performance across widening source water variability.

  3. Designing For Harmful Algal Blooms (HABs) In Surface Water Treatment Plants 3/23/2026

    The Toledo water crisis exposed treatment gaps, highlighting harmful algal blooms as a core design challenge requiring flexible, multi-barrier systems and scenario-based planning.

  4. The Future Of Surface Water Treatment In Critical Infrastructure: Why Digital Planning Is No Longer Optional 3/23/2026

    Surface water supplies most urban drinking water, but rising variability and contamination are straining ageing infrastructure—making digital planning tools essential for resilient, future-ready treatment systems.

  5. Your Chlorine Sensor Is Lying to You — Here's 65 Days Of Proof 3/17/2026

    The operators at Compton Durville Water Treatment Works thought their chlorine dosing was under control. Their membrane sensor showed residuals right at setpoint. The PID loop was doing its job. On paper, everything looked fine. It wasn't.

  6. EPA's Proposed Perchlorate Regulation: What It Means For Treatment Engineers And Oxidation Strategies 3/11/2026

    EPA’s proposed perchlorate regulation challenges utilities to integrate advanced oxidation and separation technologies, enabling reliable removal, regulatory compliance, and flexible treatment for emerging contaminants.

  7. Setting Global Standards: Inside North America's Only Full-Scale UV Disinfection Validation Facility 1/15/2026
    Portland's industry-leading facility reaches 100 reactor validations in 23 years.
  8. Electrocoagulation Unlocked 1/2/2026

    Despite electrocoagulation's demonstrated effectiveness, developing a reliable, low maintenance reactor with sufficient water processing volume has proven to be a significant engineering challenge.

  9. Custom Tank Designs That Actively Manage PFAS Mass Transfer Zone (MTZ) 12/23/2025

    As utilities prepare for the pending 4-ppt PFAS drinking water MCL, many are discovering that legacy lead/lag designs — workhorses for decades when treating contaminants in the ppm and ppb range — simply are not optimized for the parts per trillion-level (ppt) precision PFAS demands.

  10. Ion Exchange (IX) Systems 12/5/2025

    Ion exchange (IX) is a tried-and-true method of removing metals and other inorganic compounds from water. Arsenic, cadmium, chromium, copper, lead, nickel, selenium, radionuclides, and zinc are just a few examples of the compounds that our ion exchange systems have removed from water.
