(177b) Polymer Nanofiber Mats for Selective Removal of Pfas from Wastewater

This paper will present a novel technology using nanofiber mats fabricated by electrospun polymer nanofibers for selective removal of per and polyfluoroalkyl substances (PFAS) from landfill leachate. The co-contaminants, low concentration, and complexity for PFAS in industrial wastewater are big hurdles for current technologies. This method overcomes the challenges and provides a unique approach for PFAS removal. The method is a hybrid and synergistic PFAS removal with adsorption/membrane, with smart and selective adsorption feature to reduce PFAS concentration to below 70 ppt, and capable of handling co-contaminants and high loading flow rate.

The polymer nanofiber mats are regenerable after PFAS recovery for further destruction. This is a cost-effective and energy-efficient approach.
