DRINKING WATER TREATMENT RESOURCES

• Reclaiming Water From Contaminated Brine Can Increase Water Supply And Reduce Environmental Harm

  People around the globe are trying to figure out how to save, conserve, and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater. But for all the clean water they may produce, those processes leave behind a type of liquid called brine. I’m working on getting the water out of that potential source, too.
• Engineering Resilience In Water Supply: How Ozone-Based Oxidation Supports DC Water's Pure Water DC Vision

  Securing urban water futures requires shifting toward resilient, multi-source supplies. Advanced oxidation provides a critical barrier against emerging contaminants, enhancing treatment efficiency and ensuring long-term reliability without chemical residuals. Explore the foundations of engineering a decentralized, drought-proof water supply.

• Setting Global Standards: Inside North America's Only Full-Scale UV Disinfection Validation Facility

  Portland's industry-leading facility reaches 100 reactor validations in 23 years.
• Why Haven't Field Tests For Lead In Water Gone Mainstream?

  Given the maturation of sensor technology, the scientific and operational hurdles to portable lead analysis are somewhat surprising — but surmountable.
• Understanding The Limit Of Detection

  Accurate low-level turbidity monitoring requires a deep understanding of detection limits and the variables affecting measurement sensitivity. Learn how refined laboratory techniques and standardized spiking protocols ensure precision in demanding water treatment applications.

• The Laser Advantage

  High-resolution laser technology detects microscopic particles and subtle filtration breaches that traditional systems miss. By monitoring signal fluctuations and utilizing concentrated light sources, operators can achieve superior effluent accuracy and optimize filter run performance.

• Electrocoagulation Unlocked

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

• Custom Tank Designs That Actively Manage PFAS Mass Transfer Zone (MTZ) — And Why It Matters More Than Ever

  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.
