Thermal management system with sublimator and adsorbent bed

A system comprising:

• a filter device including, in serial flow order, an adsorbent bed, a biocide filter, and a particle filter, wherein the adsorbent bed includes adsorbent media that is configured to remove organic compounds from feed water that are capable of forming an adherent layer on a porous surface of a sublimator, and the biocide filter contains a halogen-release material, the adsorbent bed including first and second adsorbent media, the first adsorbent media is synthetic activated carbon that has a specific surface area of 1400 m2/g±10% and an apparent density of 0.4 g/cm3±10%, and the second adsorbent media is natural activated carbon that has a specific surface area of 1150 m2/g±10% and an apparent density of 0.49 g/cm3±0.03, and the adsorbent bed including a housing defining an influent side and an effluent side, the first adsorbent media is located on the influent side, and the second adsorbent media is located on the effluent side.
