  1. Why Vessel Design Is The Ultimate Performance Driver For Media Filters 2/16/2026

    Choosing the right media is only the first step. Vessel and underdrain design often determine whether filtration systems meet expectations — or quietly fall short over time.

  2. Can We Eliminate PFAS Forever? 1/22/2026

    Dr. Rosa Yu, National PFAS Lead at Carollo Engineers, discusses the fate of PFAS as treatment technologies evolve from removal with a PFAS byproduct to complete destruction, which would eliminate the chemicals from the water cycle, thus taking "forever" out of their name.

  3. PFAS BATs: What Are The Best Available Technologies For Treating "Forever Chemicals"? 1/22/2026

    Adam Feffer, National PFAS Practice Leader at Black & Veatch, lists the Best Available Technologies, or BATs, that the U.S. EPA has recognized for the removal of per- and polyfluoroalkyl substances (PFAS). According to the current rule (but subject to change), solutions to remove two specific PFAS — PFOA and PFOS — down to 4.0 parts per trillion must be implemented by 2029. Drinking water utilities will likely select among the treatment options shared in this clip.

  4. Engineered For Impact: The Carbon That Stands Out In PFAS Treatment 12/10/2025

    Filtrasorb 400’s agglomerated pore structure and high volumetric capacity deliver unmatched PFAS removal, longer run times, and lower lifecycle costs—outperforming direct-activated carbons in real-world and lab testing.

  5. Addressing PFAS Contamination In Cape Fear's Source Water: Calgon Carbon's Solution 11/13/2025

    The Cape Fear Public Utility Authority (CFPUA) provides drinking water to more than 200,000 residents in the Wilmington, North Carolina area. In 2017, the community learned that per- and polyfluoroalkyl substances, or PFAS as they are more commonly referred, were contaminating CFPUA’s drinking water source. This led CFPUA to partner with Calgon Carbon to install Filtrasorb® granular activated carbon (GAC) to remove PFAS from the water at their Sweeney Water Treatment Plant. With this GAC addition, PFAS concentrations were reduced to levels at or near non-detection.

  6. Proprietary Reactivation Study Demonstrates PFAS Removal And Destruction Expertise 10/15/2025

    Thermal reactivation of granular activated carbon is a proven and scalable method to achieve >99.9% destruction removal efficiency for PFAS. This process fully restores the carbon for reuse, providing a sustainable solution that breaks the cycle of "forever chemicals."

  7. Charting The Course: Q&A With Calgon Carbon's Technical Director, Dr. Angela Rodriguez 9/18/2025

    Calgon Carbon’s Dr. Angela Rodriguez shares insights on PFAS treatment, regulatory readiness, sustainability, and how innovative carbon technologies help utilities balance compliance, cost control, and environmental goals.

  8. 5 Misconceptions About PFAS Removal Technologies 7/2/2025

    This article will explore five common misconceptions about GAC and IX technologies for PFAS removal, helping utilities choose effective, site-specific treatment strategies for contaminated drinking water.

  9. Calgon Carbon Brings Nearly Seven Decades Of Industry Leading Innovative Water Treatment And Reactivation Expertise To AWWA's ACE25 6/3/2025

    Calgon Carbon, the global leader in activated carbon water treatment solutions, will be exhibiting at booth #1944 at the American Water Works Association's 2025 Annual Conference & Expo (AWWA’s ACE25) taking place June 8-11, 2025, at the Colorado Convention Center in Denver, Colorado.

  10. Multi-Contaminant Removal With Granular Activated Carbon (GAC) In Drinking Water Filtration 4/10/2025

    Learn why the U.S. EPA has recognized granular activated carbon (GAC) as a best available technology (BAT) for a wide range of substances within the same system.
