DRINKING WATER TREATMENT RESOURCES

• 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?

• Designing For Harmful Algal Blooms (HABs) In Surface Water Treatment Plants

  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.

• The Future Of Surface Water Treatment In Critical Infrastructure: Why Digital Planning Is No Longer Optional

  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.

• Your Chlorine Sensor Is Lying to You — Here's 65 Days Of Proof

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

• Filtration Media For Municipal, Industrial, And Landscape Water Treatment: Legacy And Novel Technologies

  The growing demand for water across a variety of sectors combined with the increasingly understood complexity of emerging contaminants is creating a dynamic marketplace for filtration media. The goal of selecting the right filtration media is not to meet minimum standards but to achieve the right balance of performance, durability, and operational simplicity to ensure long-term compliance and cost-effective operation.

• Testing For Yesterday's Water In A PFAS World

  Relying on assumptions when designing water treatment systems creates unnecessary financial and operational risks. Adopting predictive modeling and data-driven testing provides the precise, actionable insights required to optimize performance, manage costs, and ensure compliance.
