The Department of Defense’s (DoD) Energy and Environment Innovation Symposium was held last week (December 3 to 6, 2024) in Washington D.C. The event is the nation’s largest conference focusing on DoD priority environmental and energy issues, bringing together researchers, technology developers, defense end-users, and regulatory communities to showcase cutting edge technologies and ideas.
Cyclopure participated in a poster presentation and a technical session to report on DEXSORB® performance to remove PFAS from groundwater at DoD site in Pennsylvania. Ri Wang, VP of Environmental Engineering, presented results in a panel talk “Remediation of AFFF-Impacted Groundwater Using Novel Cyclodextrin Adsorbent (DEXSORB®)” on Thursday, December 6th.
The project demonstrated DEXSORB® effectiveness in PFAS removal, spent media regeneration, and concentration of extracted PFAS for processing by destruction technologies. Using a DEXSORB® packed bed filtration (PBF) system in pump-and-treat remediation of base groundwater, the EPA-regulated PFAS were reduced from 24 ppb to non-detect levels. Validating company regeneration methods, regenerated DEXSORB® performed with equal effect to first-use media to achieve non-detect PFAS removal. Through spent media regeneration, DEXSORB demonstrated full recovery and desorption of extracted PFAS in a concentrated waste stream.
