A test bench at scale 1/15 has been implemented in order to evaluate the performance of photocatalysis and membrane bioreaction to treat the polluted air of a spacecraft cabin containing 30 mice. Ten pollutants could be generated with low concentration and seven of them could be analysed simultaneously. Formaldehyde was tested alone because of the needed volume for its analysis. First results have shown that photocatalysis process could lead to good efficiency except for methane and formaldehyde. This one is not sufficiently eliminated. A new configuration of photocatalysor allowing higher illumination in order to try to increase formaldehyde elimination will be tested. Membrane bioreactor have to be tested too. Interesting results are expected testing the two processes in series.
