Abstract: A vessel for treatment of liquid comprising a housing having an inlet port and an outlet port connectable to an effluent pipe. An inlet pipe conducts liquid to be treated from the inlet port into the interior space of the housing. An outlet pipe conducts treated liquid from the interior space of the housing to the outlet port. The interior space of the housing defines a mechanical filtration zone and a sorption zone downstream of the mechanical filtration zone. The mechanical filtration zone has a mechanical filtration assembly adapted to receive the liquid to be treated from the inlet pipe and produce filtered liquid. The sorption zone has a sorption assembly adapted to remove at least one colloidal or soluble contaminant from the filtered liquid to produce the treated liquid. The vessel is closed after use and stored or disposed.
Abstract: A system and method for per- and polyfluorinated substances (PFAS) contaminated waste polymer solidification is provided. The method includes providing a pressure vessel containing an ion exchange or adsorption media; capturing a per- and polyfluorinated substance (PFAS) via ion exchange or adsorption in the pressure vessel thereby contaminating the ion exchange or adsorption media; sluicing the ion exchange or adsorption media from the pressure vessel into a separate disposal vessel; introducing into the contaminated ion exchange or adsorption media in the disposal vessel a component, wherein the component is one or more of a polymer, co-polymer, and a bonding agent; forming a final product of a stabilized monolith from the contaminated ion exchange or adsorption media waste and the component; and disposing of the stabilized monolith.

Abstract: A method for the solidification and packaging of waste is provided. The method includes providing a container and solidification materials, mixing the solidification materials, and inserting the solidification materials into the container at a first site location. The method also includes transporting the container having the solidification materials to a second site location, providing waste materials at the second site location, inserting waste materials into the container at the second location, and mixing the waste materials and the solidification materials in the container at the second site location. The first site location is not located on-site at a nuclear facility, and the second site location is located on-site at a nuclear facility.
