From water filtration, heavy metals sorption and removal, to persistent organic pollutant destruction we are the one stop shop for Kansas City.
SERDP Funded UV/SGM PFAS Destruction #ER19-1403
The overarching goal of this project is to validate the efficacy of a novel photocatalytic filter media (UV/SGM) for destroying per- and polyfluoroalkyl substances (PFAS) in concentrated liquid waste streams, through a series of lab-based batch and column tests. UV/SGM technology is a granular media in which a photocatalyst is embedded within the silica based structure. The media is calcined and packed around a VUV activation source. Solution passes through the column, interacting with the media and initiating photocatalysis followed by fluoride, nitrate, and sulfate liberation and subsequent mineralization. The UV/SGM unit above will be used to destroy PFAS present in concentrated waste streams such as legacy aqueous film-forming foam (AFFF) concentrate, source-area groundwater, and/or ion exchange (IX) resin regeneration waste. Specific project objectives include:
- Provide evidence that destruction of PFAS is occurring in concentrated waste streams.
- Characterize the dose-response relationship between influent PFAS concentrations and contact time for both reagent grade solutions and a concentrated liquid waste-stream.
- Assess kinetics, longevity performance trends, and capacity in rapid column studies.
- Assess the cost and performance of treatment.
