  • Patent number: 12370527
    Abstract: The invention provides methods for regenerating activated carbon that have been used in absorbing per- and polyfluoroalkyl substances (PFAS) in aqueous solution. In these methods, the activated carbon is treated with a solution of base in alcohol, which has been found to impart superior properties to the activated carbon.

  • Patent number: 12371358
    Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water is concentrated in a reverse osmosis step and salt from the resulting solution is removed in supercritical conditions prior to destruction of PFAS in supercritical conditions.

  • Patent number: 12091331
    Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.
