Synopsis:

  • Adsorption techniques are recognized as the most suitable treatment for aquatic PFAS remediation. This review discusses the numerous benefits of clay-based adsorbents, such as high loading capacity, inexpensive, and eco friendly
  • FLUORO-SORB® Adsorbent is highlighted as a commercially available clay adsorbent characterized with efficient removal of PFAS from groundwater and sediment
  • FLUORO-SORB® Adsorbent is a National Sanitation Foundation International (NSF) certified product for PFAS remediation
  • In conjunction with GAC, FLUORO-SORB® Adsorbent can improve efficiency while reducing cost of remediation overall

Brief: Clay based sorbents for PFAS remediation show strong efficacy compared to common sorbents, like GAC and Ion Exchange resins, with high loading capacity while remaining cost effective. FLUORO-SORB® Adsorbent is highlighted as a commercial sorbent for PFAS remediation with success in groundwater and sediment remediation.
