PFAS Removal for Wastewater and Remediation

Calgon Carbon has over 15 years of experience in treating wastewater, groundwater, surface water, vapor streams, and sediment and soils for PFAS compounds.

From laboratory to pilot to full-scale treatment systems, we provide state-of-the-art solutions for both removal and destruction of PFAS compounds.


Per- and polyfluoroalkyl substances, commonly referred to as PFAS, are emerging contaminants and environmentally persistent chemicals of growing concern. Many industrial operations that currently use, or have used these chemicals in the past, are being prompted to treat their wastewater or stormwater for these chemicals. Additionally, steps are being taken to address legacy PFAS sources in the environment.

There are challenges associated with PFAS removal, but Calgon Carbon has solutions. Taking a project from the laboratory, to pilot system, to full-scale treatment, we can assist with PFAS removal process development and provide the activated carbon materials and equipment to fully address PFAS sources. Our activated carbon products can be thermally reactivated by Calgon Carbon, destroying PFAS (to >99.99% efficiency), and the carbon returns to service.

Activated Carbon and Equipment Products
Activated carbon is effective at removing many types of PFAS, including C4, C6, and especially the well-studied C8 compounds such as PFOA and PFOS. Although the choice of PFAS treatment technology depends on many factors, our FILTRASORB® 400 granular activated carbon (GAC) has proven an effective and reliable option for the removal of both short and long-chain PFAS. Our FILTRASORB® GAC is a reagglomerated GAC produced from bituminous coal, and has demonstrated superior PFAS-removal capabilities to coconut shell-based GAC. An example of the high performance of the FILTRASORB® can be seen in this case study.

GAC Reactivation Services and PFAS Destruction Capabilities

In addition to providing the GAC products and adsorber equipment for PFAS removal, Calgon Carbon also provides services to exchange spent carbon and reactivate the material, removing PFAS from the carbon and thermally destroying the PFAS (to >99.99% efficiency) in a high-temperature process. After reactivating the carbon, it can be returned to service. Calgon Carbon describes our reactivation process and our understanding of its impact on the fate of PFAS this memorandum, and we have conducted research demonstrating the efficacy of our carbon reactivation process for PFAS destruction, published in a peer-reviewed article in Remediation. This study is publicly available under the title “Thermal destruction of PFAS during full-scale reactivation of PFAS-laden granular activated carbon” and a webinar detailing the study is available by requesting access to our suite of on-demand PFAS removal webinars.

Calgon Carbon's FILTRASORB® GAC can remove a wide range of concentrations of of PFOA and PFOS to non-detect levels. Our studies show that reagglomerated, coal-based GAC performs significantly better than coconut for PFOA and PFOS removal. Even if local regulations require lower PFAS concentrations than the EPA health advisory, GAC is an effective solution.

Short-Chain PFAS

Coal based GAC, especially virgin material, effectively removes short chain PFAS effectively. Our reagglomerated bituminous coal-based FILTRASORB® GAC product, as well as our ion exchange products and services, will remove an array of PFAS including both long- and short-chain compounds.
