Novel Method Development for Pfas Contaminants Treatment in Landfills Leachates

This paper will present a novel approach that combine with sorbent and chemical reduction for the selective removal and destruction of per- and polyfluoroalkyl substances (PFAS) from landfill leachate. Although the co-contaminants, low concentration, and complexity for PFAS in industrial wastewater are big hurdles for current technologies. this method will overcome the challenges and provide a unique approach for PFAS removal.

The advantages of this technology include:
1) Capable of handling co-contaminants;
2) High loading flow rate;
3) Energy-efficient re-generable with PFAS recovery for destruction.

This method has the potential to reduce the combined PFAS concentration to below 70 ppt for wastewater treatment market, which is growing 19% annually to $11 billion until 2025. The technology is cost-effective and compatible with other treatment processes.
