1. Cleaning AFFF Fire- Fighting Systems The PerfluorAd system is ideal for cleaning out fire-fighting systems, such as trucks, storage vessels, hoses and piping, impacted by aqueous film forming foam (AFFF) that contain per- and polyfluoroalkyl substances (PFAS). • Patented PerfluorAd technology can remove 99.9% of anionic PFAS by flocculation • Works exceedingly well at elevated PFAS concentrations • Performs in the presence of dissolved organic carbon, surfactants and other constituents • Stand-alone system or with activated carbon or • ion exchange resin for polishing • Laboratory study identifies the ideal dose of PerfluorAd for maximum PFAS removal • Mobile treatment system performs, at your site, with • clean-outs in three to five days Total PFAS Before and After Cleaning with PerfluorAd Elimination Rate [%] for Total PFAS After Cleaning with PerfluorAd 100.00 797.16 99.90 total PFAS [µg/l] Elimination rate [%] 800 99.80 508.98 85.24 99.70 478.85 0.22 600 Vehicle no. 5 99.60 0.22 Vehicle no. 4 400 0.24 99.50 Vehicle no. 3 0.21 99.40 80.27 200 Vehicle no. 2 99.30 0.39 0 Vehicle no. 1 99.20 1 2 3 4 5
