Novel Adsorbent for Leachate Treatment Systems

This session presents the results of several bench scale studies showing PFAS removal from landfill leachate using a novel adsorbent developed by ECT2, provided as part of a system to chemically remove PFAS from landfill leachate. Focusing on development of a low-cost adsorbent derived from recycled material that would otherwise be considered waste has yielded a new PFAS removal alternative for landfill leachate at a much lower price point than other available technologies. The chemical treatment system uses conventional equipment and is extremely operator friendly, making it well suited for remote systems where staffing is limited. Residuals are processed periodically using conventional filter press technology to make a 25–30% dewatered cake, or they can be processed through a variety of PFAS destruction systems. This presentation will provide data summarizing system performance as well as operating and capital costs for treating several different landfill leachates.
