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 disposal system is provided for transferring material to a container. The disposal system includes a discharge chute having a mating surface. The mating surface is configured to engage with a container, and the discharge chute is configured to extend and retract so that the mating surface moves along a path between an extended position and a retracted position. The disposal system also includes at least one controller that is configured to cause the discharge chute to extend and retract.

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 system and method for purifying and recycling cold wastewater is provided. Contaminated wastewater is supplied at a temperature no greater than 45° F. through an ultrafilter. The wastewater is fed through a reverse osmosis filter unit. Clean water is reused whereas reject is sent to disposal. Cold temperatures are preferably maintained throughout the treatment process.

Abstract: A method is disclosed for treating liquid radioactive waste to provide reusable water, while reducing the overall volume and water content of the removed solid contaminants. The process is carried out in two separate stages, generally in at least two separate locations. In the first stage, the waste is pretreated at a first site, preferably where the waste was generated, to provide clean water, and a concentrated fraction containing removed suspended and dissolved solids, as well as some remaining water. The pretreatment typically involves passing the liquid waste through one or more microfilters, ultrafilter or nanofilters in combination with a reverse osmosis membrane. In the second stage of the process, the concentrated waste fraction, containing the removed solids, is transported to a second site, where it is thermally treated to remove the remaining water and reduce the volume of the remaining solids.
