Abstract
Poly and per-fluoroalkyl substances (PFAS) are a group of synthetic chemicals that have negative consequences on human health. AFFF (aqueous film-forming foam) is a fire suppressant comprised of highly concentrated PFAS. Because of the potential harm of PFAS to human health and the environment, AFFF will be phased out by the Department of Defense (DoD) starting in October 2025. AFFF has been used for decades by airports and other public and private entities, leading to severe environmental contamination. Found in a variety of sources, notably groundwater and soils, the conventional treatment of AFFF for the purposes of remediation is costly and not always successful. Therefore, new water treatment technologies need to be implemented to address this harmful contaminant. The purpose of this research project is to contribute to the construction and bench testing of a high-recovery closed-circuit membrane filtration (CCMF) system. This will later be used alongside surface-active foam fractionation (SAFF®) and hydrothermal alkaline treatment (HALT) to be deployed to a DoD site to treat a PFAS impacted groundwater matrix for up to 2 months. PFAS removal, residual management and energy consumption will be the metrics of comparison to other PFAS treatment technologies to validate whether this technology is viable for the treatment of PFAS contaminated matrices. For this particular research, the CCMF bench testing results and construction process will be presented.
