Abstract Scope |
This talk will present recent progress toward development of an economical and energy-efficient process to pretreat waste streams for removal of per-/polyfluorinated alkyl species (PFAS). PFAS have historically been used across a broad range of industries for a wide variety of applications,but are highly refractory and bio-accumulative and have the potential to cause numerous adverse health effects. Thus, multiple regulatory agencies, including the U.S. and various state EPAs, are in the process of defining actionable maximum contaminant limits for numerous PFAS. Faraday has recently demonstrated a pulsed-waveform electrocatalysis approach for PFAS destruction with clearly superior performance to direct-current methods, enhancing destruction of more-challenging short-chain PFAS and enabling PFAS destruction even in complex matrices. Cost analysis estimates indicate that the use of pulsed waveforms has the potential to provide appreciable reductions in OPEX and favorable overall CAPEX/OPEX. |
