Sustainable Remediation of pfas

PFAS remediation

While activated carbon has its uses for in-situ applications, Ejlskov has found that it has limitations in dealing with perfluoroalkyl acids (PFAAs). Activated carbon is not the best technology for remediating these recalcitrant compounds.

The solution? Think differently. Consider surface-modified organoclay like Fluorosorb.

Fluorosorb has proven to outperform activated carbon and anion exchange resins in adsorbing PFAAs per unit weight of adsorbent. With different particle sizes, it can be applied in treatment beds or injections.

Ejlskov has been licensed by CETCO (along with its RPI Group partners) to provide in-situ injection solutions for clients needing help with PFAAs.

Fluorosorb can be used in source areas to reduce PFAA leaching and as permeable reactive barriers to control PFAA migration. Importantly, unlike colloidal activated carbon, Fluorosorb’s particle size ensures it stays where injected and does not move with groundwater. This prevents simply moving the PFAA problem from one location to another.

However, Ejlskov’s overall approach does not change. We always focus on optimizing remediation design to understand site conditions and provide the most cost-effective and timely solution when using Fluorosorb.
