  1. Inside the Furnace: How Thermal Reactivation Is Reshaping Municipal Water Treatment 3/17/2026

    In this episode of the Water Online Show, host Travis Kennedy sits down with Elisa Mayerberger of Calgon Carbon to explore the growing importance of thermal reactivation in water treatment.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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."

  8. 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.

  9. 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.

  10. 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.
