Introducing AquaKnight. A new hero in the fight against PFAS.

Welcome to the battle against PFAS. We are ready and prepared to win!

For over 20 years, Calgon Carbon has been the sought-after leader in removing PFAS from both drinking water and wastewater.

Like many towns and communities across the United States, Calgon Carbon is prepared to meet the EPA’s upcoming and enforceable Maximum Contaminant Levels (MCLs) and fully equipped to help both public and private water utilities to do the same.

Let’s be clear…we no longer consider it a “forever chemical.” To us, it is “forever no more.”

Newly Published Peer-Reviewed Study in 2025!

Destruction of PFAS During Thermal Reactivation of Granular Activated Carbon Used in Potable Water Treatment

Calgon Carbon recently published its second peer-reviewed white paper on the reactivation of PFAS laden spent carbon, titled “Destruction of PFAS During Thermal Reactivation of Granular Activated Carbon Used in Potable Water Treatment,” in the Remediation Journal. This study not only reaffirms the proven performance of reactivation but uniquely validates the effectiveness of Calgon Carbon’s proprietary full-scale drinking water reactivation process, commonly referred to as custom municipal reactivation.

FILTRASORB® Activated Carbon

If there was ever a name brand carbon, this is it and for good reason. From creation to application, this made in the U.S.A. powerhouse has demonstrated superior PFAS-removal capabilities and meets the strictest regulations. Effectively treating to non-detect levels means < 1 drop in 20 Olympic size pools. This requires expertly engineered and proven solutions, not just products…this is the Calgon Carbon difference.

AquaKnight™ Equipment Systems

The presence of an AquaKnight system symbolizes a community’s commitment to pristine water quality. Designed with meticulous attention to detail and advanced testing, AquaKnight systems create the ideal environment for the activated carbon to remove contaminants 24/7. Beyond their functional excellence, these systems offer flexibility in customization, ensuring they integrate seamlessly into any town’s infrastructure.

Reactivation

Our commitment to sustainability and efficiency extends beyond the initial filtration process. Once FILTRASORB and AquaKnight have purified a community’s water, the battle against PFAS persists as we undertake the reactivation of spent carbon. Calgon Carbon’s proprietary full-scale drinking water reactivation process is effectively removing PFAS to non-detectable levels and enabling the effective recycling of reactivated carbon in drinking water treatment, as per Calgon Carbon’s recently published second peer-reviewed study. Through high-temperature reactivation, municipalities and industrial users can recycle spent activated carbon while removing the PFAS contaminants below detectable limits from the carbon with a destruction removal efficiency of > 99.9%.Reactivation epitomizes our innovative approach to granular activated carbon disposal and reuse, honed over 50 years of global experience.
