Further development of toxic trace contaminant removal systems for atmosphere of manned space stations

The problem of maintaining toxic trace contaminants in the atmosphere of manned space vehicles within acceptable limits is still being solved. This is explained by both a great number of classes of toxic contaminants in the atmosphere composition, and complexity of trace contaminant removal. Special systems for removing toxic trace contaminants from space station atmosphere in order to maintain their acceptable levels have been developed. The paper presents advanced combined equipment for removing harmful contaminants, which normally jointly operates both adsorption and photo catalysis units. Such equipment makes it possible to remove not only harmful contaminants, but also microorganisms and fine dust, thus increasing the biological full-value of the space station atmosphere.
