  • Patent number: 10199129
    Abstract: The method and system disclosed provides radionuclide contamination mitigation by applying an aqueous carrier solution comprising a cation to a surface bearing a radionuclide contaminant to cause the radionuclide contaminant to enter solution forming a laden solution, then contacting the laden solution with a sequestering agent to bind to the radionuclide contaminant to form a laden sequestering agent. The removal and sequestration of the radionuclide contaminant from the contaminated surface leads directly to a reduction in the amount of radiologically-impacted critical infrastructure and the environment. The method and system are able to be performed or utilized economically with materials quickly available in the event of a radiological dispersion event.

    Abstract: An exfiltration apparatus for removing contaminants from a fluid includes a housing, a filter portion positioned within the housing, and a particulate collecting member. The housing defines a fluid flow path extending from a fluid inlet disposed on a first side of the housing to a fluid outlet disposed on a second side of the housing. The particulate collecting member is disposed within the housing between the fluid inlet and the filter portion. The particulate collecting member includes a recessed particulate collecting portion proximate the filter portion and a raised apertured portion proximate the fluid inlet. Fluid flowing along the fluid flow path passes through the particulate collecting member and through the filter portion before exiting through the fluid outlet.
