DRINKING WATER TREATMENT RESOURCES

• 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?

• 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.

• Scaling Water Reuse: New State Regulatory Guides And What They Mean For Treatment Design

  Emerging state water reuse regulations are driving adoption of ozone and advanced oxidation, requiring flexible, high-performance systems to meet pathogen, trace organic, and DBP control objectives.

• EPA's Proposed Perchlorate Regulation: What It Means For Treatment Engineers And Oxidation Strategies

  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.

• Ozone Contactors: The Engineering Variable That Determines Oxidation Success

  Ozone system performance hinges on reactor design, not generator size. Efficient mass transfer, hydraulic integrity, and contact time ensure consistent oxidation, reduced energy use, and reliable treatment results.
