The concept for the “Biological Air Filter” (BAF) is based onto the property of certain selected microorganisms for the complete oxidation to water, carbon dioxide and salts, of gaseous contaminants. The EXEMSI manned space mission simulation campaign offered a good opportunity for testing the performances of an experimental BAF on a real confined atmosphere.

Preliminary development of a core water-recycling system for potable water reprocessing has been performed, supported by a critical assessment of the required architecture and extensive experimental testing of materials, technologies and procedures. The functional architecture of the water-recycling system is characterised by a Core Water-Recycling System (CWRS) reprocessing potable water from moderately contaminated water such as hygiene water and condensation and CO2-reduction waters, and a complementary treatment technology allowing further processing of highly contaminated sources such as urine and brines from the core system. The quality of this last processed water is sufficient to allow its reprocessing by the core system. Technologies involved in the core water-recycling system and complementary brine recycling system are based on chemical treatment, ultra-filtration, reverse osmosis at acidic and neutral pH, photo-oxidation and phase-change.
