Drinking Water Treatment Case Studies and White Papers

1. What Utilities Don't Know About GAC Reuse For PFAS 9/9/2026

   For utilities building PFAS treatment systems, thermal reactivation of spent granular activated carbon (GAC) may sound like the obvious answer. However, service provider availability and location, specific media acceptance criteria including quantity thresholds, restrictions on GAC type and condition, and regulatory uncertainty can all determine whether reuse is a viable option. 

2. Sample Collection And Storage: Protecting Water Quality Results From The Start 8/18/2026

   Flawless analytical procedures mean little if samples are compromised before testing. Discover how proper container selection, representative collection techniques, and rigorous preservation protocols prevent pre-analysis error to ensure defensible, accurate water quality results.

3. Spectrophotometry Theory And Practice 8/18/2026

   Spectrophotometry is one of the foundational analytical techniques used to quantify substances in solution by measuring their absorption of light. Understanding the relationship between electromagnetic radiation, wavelength selection, and absorption behavior is critical for developing accurate analytical methods and generating reliable measurement data.

4. Reverse Osmosis Gets Smarter: New Technologies Target Energy Use And Membrane Fouling 8/18/2026

   Nearly 45–60% of a reverse osmosis (RO) plant's operating cost is linked to energy consumption, while membrane fouling can reduce productivity by 15–40% and increase cleaning costs by thousands of dollars annually. The newest generation of RO systems is therefore focused on reducing energy demand, extending membrane life, and using intelligent monitoring to predict fouling before performance declines.

5. How To Check Colorimetric Accuracy And Troubleshoot Unexpected Results 8/17/2026

   Achieve defensible testing results by mastering analytical controls. Learn how strategic blank corrections, scheduled primary and secondary standard verifications, and systematic troubleshooting eliminate measurement errors and simplify regulatory compliance across everyday laboratory operations.

6. When Water Test Results Don't Add Up 8/17/2026

   Undetected interferences in water analysis lead to reporting errors and costly compliance failures. Learn how to identify sample matrix disruptions using spike-and-recovery testing and apply practical lab techniques to ensure accurate, compliant data.

7. PFAS-Selective Single-Use Ion Exchange Resin: Environmental Discharge And Remediation 8/10/2026

   Effective PFAS remediation demands precise prefiltration, controlled hydraulics, and optimized vessel configurations to prevent media fouling and premature contaminant breakthrough. Read the guide to implement best practices for maximum treatment efficiency.

8. PFAS-Selective Single-Use Ion Exchange Resin For Drinking Water Systems 8/10/2026

   Achieving reliable drinking water decontamination using selective single-use ion exchange media requires careful hydraulic management, targeted prefiltration, and proper lead-lag vessel engineering to protect media integrity, prevent premature breakthrough, and maintain consistent effluent quality.

9. Revolutionizing Water Filtration: Inside Harmsco's Industrial And Municipal Solutions 8/5/2026

   In this episode of The Water Online Show, host Angela Godwin sits down with Harmsco’s German Gutierrez and Cyndi Benson to explore how a company that began selling pool cartridges has evolved into a global filtration leader.

10. From Two Data Points To A Living Map: Proactive Distribution Management 7/27/2026

    Relying on sparse monitoring points forces utilities to infer water quality across broad networks. Continuous, multi-point data collection delivers real-time visibility, allowing operators to detect trends early, optimize maintenance, and transition to proactive distribution management.
