Prospects of Novel Technologies for PFAS Destruction in Water and Wastewater
AI summary Read the abstract
This review examines novel technologies for permanently destroying per- and polyfluoroalkyl substances (PFAS) in water and wastewater, critically evaluating advanced oxidation, electrochemical, and thermally driven approaches capable of breaking the extremely strong C-F bond to fully mineralize these persistent pollutants.
PFASs, compounds to which the C-F bond—the strongest known in nature—bestows high resistance to degradation, have been detected in surface and groundwater worldwide, including drinking water supplies. Current regulations on long-chain PFASs resulted in the shift to short-chain PFASs in industrial uses, with their increasing environmental detection. Currently, suggested BATs for PFAS removal from aqueous solutions include mainly adsorption or membrane filtration; however, different response behavior to even simple treatment was observed concerning long- and short-chain PFAS molecules. In order to permanently destroy (mineralize) PFASs and their precursors, treatment technologies that can deliver sufficiently high energy to crack the C-F bond are needed. This paper discusses current PFAS removal technologies and state of the art advanced methods for PFAS removal and destruction, critically discussing their efficiency, applicability, emerging issues, and future prospects.

Leading Techniques for Per- and Polyfluoroalkyl Substances (PFASs) Remediating in Water and Wastewater
AI summary Read the abstract
Per- and polyfluoroalkyl substances (PFAS), often called "forever chemicals," are highly persistent contaminants found in water and soil worldwide. This review evaluates the leading remediation techniques available for removing PFAS from contaminated environments, comparing their effectiveness, scalability, and cost. Given PFAS's resistance to natural degradation, engineered removal strategies are essential for protecting drinking water sources and ecosystems.

Breaking the “Forever Chemical” Cycle: A Critical Review of Per- and Polyfluoroalkyl Substances in Solid Waste Sources and Their Fate During Thermal Treatment
AI summary Read the abstract
A critical review of thermal treatment technologies for PFAS-containing solid waste found that incineration and smoldering combustion can exceed 99.99% destruction efficiency but release problematic short-chain byproducts, while pyrolysis risks phase transfer into oils. PFAS and microplastics frequently co-occur in solid waste streams, and understanding thermal treatment limitations is essential for developing comprehensive plastic waste management strategies.
