Abstract: Apparatus for treating water including PFAS includes influent piping adapted to conduct untreated water from an untreated water source. A first process vessel is fluidly coupled to the influent piping to receive the untreated water. First transfer piping is adapted to conduct first vessel processed water from the first process vessel. A second process vessel is coupled to the first transfer piping to receive the first vessel processed water. An ion exchange injection mechanism is adapted to supply ion exchange material to the second process vessel. Second transfer piping is adapted to conduct second vessel processed water from the second process vessel.

Abstract: A vessel for removing radionuclides from a liquid. The vessel comprises a shielded housing comprising an outer shell and an inner shell disposed within the outer shell. The housing defines an ion exchange chamber between the inner and outer shells. The vessel also comprises an inlet fluidly coupled with the ion exchange chamber, the inlet being configured for fluid communication with a source of the liquid, and an outlet fluidly coupled with the ion exchange chamber, the outlet being configured for fluid communication with a destination of the liquid. The vessel further comprises a first fluid passage extending between an exterior of the vessel and the inner shell and a second fluid passage extending between the exterior of the vessel and the inner shell.

Abstract: A method for treating a liquid waste is provided. The method includes supplying the liquid waste to a plurality of cross flow filters from at least one high level waste tank; filtering the liquid waste via the plurality of cross flow filters to form a clarified salt solution; removing at least one radionuclide from the clarified salt solution via a plurality of elutable ion exchange columns filled with an ion exchange media to form an eluate and a decontaminated salt solution; and removing at least one radionuclide from the eluate via a first non-elutable adsorption component to form a dewatered radionuclide sorbent and a decontaminated eluate solution.

Abstract: A vessel for both treatment of radioactive wastewater and disposal of radioactive waste contained therein. The vessel comprises a main vessel structure including a shell formed of a metal material and a liner integrally coupled to the interior surface of the shell. The liner is preferably formed of a plastic material, such as high density polyethylene. Waste treatment equipment for treatment of the radioactive wastewater is provided within the shell. Ion exchange resin is typically located in the main vessel structure which, when spent, constitutes the radioactive waste which is subject to disposal. The vessel is preferably configured to function as a High Integrity Container (HIC).

Abstract: Deaerated oil having a level of less than about 0.10% by volume of dissolved oxygen is heated at a temperature between about 530.degree. F. (277.degree. C.) and about 650.degree. F. (343.degree. C.) and stripped with a stripping medium with a molar ratio of stripping medium to oil of between about 0.05 and about 9.7, at an absolute pressure of between about 0.5 mm Hg and about 50 mm Hg., for a time of between about 5 seconds and about 15 minutes. The combination of stripping parameters is selected so that the stripping factor "f" is greater than about 0.6, where f=KP.sub.v S/PO, where K is between about 1 and about 200, and where P.sub.v (the vapor pressure of the component to be stripped) is not more than about 0.1 mm Hg at 500.degree. F. (277.degree. C.) and not more than about 2.0 mm Hg at 600.degree. F. (343.degree. C.).
