NSF lists a number of ways to remove PFAS from drinking water and it appears that all of them are a form of filtration—trapping PFAS on an absorber (source: NSF). It appears that activated carbon is one of the more popular absorbers, used in the industry (source: Jacobi and Calgon).

Filtration seems to work. Are we safe then? We at AAPlasma don’t think so. Water filter recycling seems to not be a viable option (source: BOS, Recycle Nation, thehomeHardware). Thus, we are focused on “Plasma-Enhancement of Absorbers for Improved Removal of PFOS and PFOA from Water” in our Phase II project, funded by the EPA (source: FPDS).

Based on the successful lab-scale demonstrations in Phase I, and now partnering with water filtration companies, AAPlasma plans to develop a prototype system for treatment of spent filter material on the scale of interest to water utility companies and water filtration industry.
