Granular activated carbon (GAC) is the most widely used and well-established treatment technology for the removal of PFAS contaminants from drinking water and wastewater. After the GAC has reached the end of its useful service life and becomes spent carbon, it is common practice in industry to thermally treat it in a process known as reactivation. In light of this, a thorough program of testing was carried out at a full-scale, RCRA certified GAC reactivation facility during the reactivation of a load of GAC known to contain adsorbed PFAS. Reactivation and industrial reuse present a viable pathway for “disposal” of GAC used in both point-of-entry (POE) and point-of-use (POU) systems, assuming that the media can be collected at a central location.
