PLATFORM PRESENTATION

Technical Solution for Removal of PFAS in Water

Close to an airport in Nuremberg (Germany), investigations showed that PFAS (per- and polyfluorinated alkyl substances) were detectable in the groundwater down gradient of the airport site. Further investigation identified a fire-fighting training area as the source area of PFAS contamination in both the soil and groundwater. The maximum level of PFAS in the groundwater measured about 777 µg/l (about 48% PFOS) with an average value in the wells of about 357 µg/l. A series of field tests on various remediation technologies were conducted and the selected remedial method captured the PFAS and generated micro floccs. The pre-treatment generating micro floccs was successful in removing more than 90% of the PFAS and required no carbon change-out, without the pre-treatment, eight carbon change-outs would have been required. Both field test and full-scale results will be presented.
