These two webinars focus on research efforts to develop and demonstrate technologies for PFAS destruction in concentrated liquid waste streams. This first study titled "Validation of a UV/TiO2 Activated Alkaline Media for Destruction of PFAS in Concentrated Liquid Waste Streams" focuses on validating a UV/TiO2 activated alkaline media technology for the destruction of PFAS (Per- and Polyfluoroalkyl Substances) in concentrated liquid waste streams. The UV/SGM (Sodium Gluconate Mediated) technology offers a promising solution for treating complex liquid waste matrices. This includes waste streams like regenerable ion exchange resin concentrate, foam fractionate, reverse osmosis reject, and neat AFFF. The second research project titled "Demonstration of a Pilot-Scale Continuous Hydrothermal Alkaline Treatment (HALT) System for DoD-Relevant, PFAS-Impacted Matrices" investigates the Hydrothermal Alkaline Treatment (HALT) process as a method for destroying PFAS in complex wastewater matrices. HALT operates under subcritical water conditions (>300?C, ~20 MPa, pH > 14), converting PFAS into inorganic salts such as NaF and Na2CO3. This method is distinguished by its ability to treat high total dissolved solids and total organic carbon content in wastewater, achieving over 99% destruction efficacy for all types of PFAS.
