PFAS in Water: Removal, Treatment, & Destruction

June 8, 2021 @ 1:30 pm - 3:00 pm

The webinar was presented for informational purposes. The views expressed do not necessarily reflect those of each of the NEWMOA-member states, and and the strategies and technologies discussed should not be considered an endorsement by NEWMOA or its members.

The webinar included the following presentations:

Dr. Charles Schaefer, CDM Smith [PDF] presented Removal & Destruction of PFAS in Water. The presentation will discuss removal of PFAS from surface and groundwaters using granular activated carbon (GAC) and anion exchange resins (AERs), including impacts of water geochemistry and co-contaminants on effectiveness, and potential secondary water impacts. Application of electrochemical oxidation for PFAS destruction in brines used for AER regeneration was also examined.

Dr. Michelle Crimi, Clarkson University [PDF] presented Optimization of Regenerable Ion-Exchange for PFAS Groundwater Treatment – Outcomes from Two SERDP & ESTCP Projects. The presentation summarized work on two DoD projects funded by SERDP and ESTCP to develop and validate a treatment train approach for managing PFAS-contaminated water. PFAS are first concentrated onto a regenerable ion exchange resin. The resin regenerated for its reuse and the PFAS are separated from the regenerant solution allowing it to also be reused. PFAS in the highly concentrated residue are then destroyed by plasma treatment. The team from Clarkson, Texas Tech, ECT2, Wood, and NAVFAC are working to optimize each step and is currently validating performance at Pease Air National Guard Base.
