Testing of Russian ECLSS - Sabatier and Potable Water Processor 941252
Hamilton Standard Space Systems International, Inc. (HSSSI) has obtained and is currently testing a variety of Russian life support hardware. These units have been or are contemplated for use on Mir I and II space stations.
This paper presents the current status of performance testing of a Sabatier Carbon Dioxide Processing Unit (CDPU) and components of a Potable Water Processing System (PWP). These systems were fabricated by NIICHIMMASH, the supplier of these units to the Russian space program. It is the intent of this testing program to obtain a data base for technology comparisons to support planned and future international missions.
For the CDPU, reactant conversion efficiencies in excess of 99 percent have been noted for the variation in test conditions with 2 to 6 man processing (flows) tested. The CDPU's effluent water has been produced at anticipated rates and is relatively contaminant free. Additionally, the CDPU's separator and pump assembly has performed in an efficient manner.
A description of the Russian PWP system is provided. Details of PWP test program with challenge solutions simulating the humidity condensate on the Mir space station are noted. A discussion of NIICHIMMASH water reclamation processing approach and hardware is addressed. At this time, after processing over 300 liters of simulated humidity condensate, the PWP purification column unit has provided potable quality water with TOCs < 0.5 ppm and conductivities < 2.6 umhos/cm.
