• 4 Essential Truths About Carbon Reactivation

  Long-standing myths about GAC reactivation are being increasingly challenged, revealing performance, cost, and sustainability benefits many utilities may have overlooked.

• Mass Transfer Efficiency: The Most Important Metric In Ozone System Design

  Ozone output doesn’t guarantee performance. Learn how mass transfer efficiency determines how much ozone dissolves, drives treatment results, and impacts energy use and system design.

• The Hidden Legionella Risk In Closed-Loop Systems

  For a long time, it’s been assumed that closed-loop water systems — those commonly found in building heating systems, air-conditioning units, and cooling systems — are at a low risk for Legionella. However, there are many reasons why closed-loop systems can actually inadvertently promote the risk of Legionella.
• UV, Ozone, Or Chlorine: Which Solution Is Best For Your Treatment Plant?

  No single disinfection method does it all. Utilities are combining chlorine, UV, and ozone to build more effective, flexible treatment strategies for today’s water challenges.

• Case Study: Groundwater DWTP (AK) - DEXSORB Full-Scale

  A DWTP client in Alaska detected elevated PFAS contamination levels in two groundwater wells supplying drinking water to 85 service connections. PFAS concentrations are provided in Table 1, where combined concentration of EPA PFAS6 was detected at 490 to 810 ppt.

• Is Monitoring Of Total Or Free Chlorine A Better Option For Dechlorination Control?

  Accurate dechlorination control requires monitoring all residual oxidants that threaten membrane integrity. Total chlorine analysis provides the necessary precision at ultra-low levels, ensuring comprehensive protection against oxidative damage while maintaining reagent stability during intermittent system operations.

• Designing Resilient PFAS Treatment Strategies For Water Agencies

  Water agencies across the U.S. are facing a rapidly evolving regulatory landscape for per- and polyfluoroalkyl substances (PFAS) that poses a conundrum: Should they take a cautious or aggressive approach to treating PFAS contamination in their water system?
• Surface Water vs. Groundwater: Strategic Infrastructure Tradeoffs For Growing Communities

  What's really at stake when choosing between surface water and groundwater? The answer shapes water security for decades.
