Comparative Analysis of Treatment Technologies for PFAS in Water Public
Downloadable ContentDownload PDF
Many per- and polyfluoroalkyl substances (PFAS), which are characterized by fluorinated carbon chains, have been identified as chemicals of concern due to their toxicity, widespread distribution, and persistence in the environment. This study analyzes the conventional and novel treatment technologies of activated carbon, anion exchange resin, high-pressure membranes, electrocoagulation, foam fraction, ozonation, molecular imprinted polymer adsorbents, bioremediation, electrolysis, photolysis, and sonochemical degradation in regard to PFAS removal. Further optimization of treatment technologies to remove PFAS from water is necessary. Future research will continue the development of treatment trains to enhance removal efficiency and cost-effectiveness.
