Advances in treatment technologies for PFAS removal are rapid, but their efficiency and practicality need improvement. Successfully removing a certain level of PFAS calls for cautious implementation of long-term strategies. Emerging treatment technologies include ion exchange, adsorption, advanced oxidation, and membrane separation.
Despite the rapid advances in treatment technologies for per-fluoroalkyl and poly-fluoroalkyl substances (PFAS) removal, the efficiency and practicality of these technologies would be either questionable or not cost-competitive sometimes. Several studies have successfully removed or destroyed PFAS from aqueous solutions but only to a limited level. Nevertheless, the treatment technologies are still evolving, and thus, long-term strategies should be implemented with caution. In this study, the physical and chemical properties of PFAS were provided. The emerging treatment technologies for PFAS removal, such as ion exchange resins, adsorption, advanced oxidation process, and membranebased separation, are briefly reviewed in this paper. The treatment's mechanisms and future research trends are covered to provide insight into the technologies above. The study covered the treatment technologies for PFAS removal systematically and hierarchically and delivered a guideline for creating efficient and robust treatment technology for PFAS treatment.
