Presentation Description:
PFAS Selective Single Pass Ion Exchange Resins for treatment of per- and polyfluoroalkyl substances are an affordable and established technology. Extensive piloting, modeling, dozens of treatment sites and hundreds of point-of-entry / point-of-use systems are using IX. PFAS selective resins have been developed specifically for drinking water applications over the past several years with great success.
In this presentation, the audience will learn how PFAS Selective Single Pass Ion Exchange Resin has successfully brought contaminated water to non-detect for PFAS in drinking water at least six sites. A review of lessons learned will also be conducted. As many sites have started using ion exchange resin for PFAS, there is much learning that can be shared. We will review design considerations and how they have translated to full scale savings. We will share the (unwelcome) startup surprises and how they can be prevented. We will highlight award-winning projects and the best practices that have contributed to their success.
