Abstract Scope |
Wastewater treatment demands technologies that can efficiently remove CECs from effluent discharge. Per-/polyfluorinated alkyl species (PFAS) and pharmaceuticals are separately recognized as emerging contaminants due to their bioactivity, wide usage, and potential health and ecological risks. In this presentation, we will discuss our recent progress concerning the development of an economical and energy-efficient process for remediation of these CECs. Within this context, Faraday has recently demonstrated a continuous pulsed-waveform electrochemical technology to destroy CECs in industrial wastewater, landfill leachate, and groundwater from soil. As a specific example, preliminary tests revealed that a boron-doped diamond electrocatalyst demonstrated PFOS destruction of 97%+ within one hour of processing, as measured by quantitative LC-MS analysis. The proposed technology for CECs degradation can be can be flexibly applied at large wastewater treatment facilities and also on a smaller scale for applications like on-site wastewater systems to reuse water from buildings, toilets, and showers. |
