Abstract：

This paper mainly studied the separation properties of water/gas membrane separator under microgravity in long term manned space flight. The ground test system under microgravity was set up, and the influence of pressure drop、volume ratio of water/gas mixture and gravity factor on separation performance of water/gas separator with hollow fiber membrane was investigated. It was found that the water permeate flux of water/gas membrane separator increased with the increase of pressure drop and the volume ratio of water/gas mixture. Gravity almost did not affect the separation performance. It is proved that hollow fiber ultrafiltration membrane can be used to separate water from water/gas mixture under microgravity, and it can provide support for the application of membrane water/gas separator in manned space flight.
