    Abstract: A contaminant removal system for removing a contaminant from an environment includes a gas separator, a scrubber-separator downstream of the gas separator, and a stripper-separator downstream of the scrubber-separator. The gas separator is configured to receive a cabin air stream from the environment and concentrate the contaminant from the cabin air stream to produce a concentrated cabin air stream. The cabin air stream includes the contaminant, and the concentrated cabin air stream has a higher concentration of the contaminant than the cabin air stream. The scrubber-separator is configured to absorb the contaminant from the concentrated cabin air stream into a liquid sorbent and discharge a clean air stream to the environment. The stripper-separator is configured to desorb the contaminant from the liquid sorbent into a contaminant stream.

    Abstract: A system and method for sanitizing a surface within an aircraft includes emitting UV radiation from a UV radiation source toward the surface, and emitting visible light from a visible light source toward the surface. A UV sensor senses an intensity of the UV radiation reflected by a reflector that is disposed on a least a portion of the surface and a visible light senses an intensity of the visible light reflected by the reflector. A processor processes the UV intensity signal and the visible light intensity signal to determine the intensity of the UV radiation on the surface and a UV dose to the surface.
