Abstract: This disclosure provides an integrated system and method for producing purified water, hydrogen, and oxygen from contaminated water. The contaminated water may be derived from regolith-based resources on the moon, Mars, near-Earth asteroids, or other destination in outer space. The integrated system and method utilize a cold trap to receive the contaminated water in a vapor phase and selectively freeze out water from one or more volatiles. A heat source increases temperature in the cold trap to vaporize the frozen contaminated water to produce a gas stream of water vapor and volatiles. A chemical scrubber may remove one or more volatiles. The integrated system and method utilize ionomer membrane technology to separate the water vapor from remaining volatiles. The water vapor is delivered for crew use or delivered to an electrolyzer to produce hydrogen and oxygen.

Abstract: The invention relates to hydrophilic membranes which are supplemented or treated with a non-ionic surfactant and processes for preparing such membranes. The membranes are particularly suitable for plasma separation or for haemodialysis and haemodiafiltration, but can also advantageously be used in other applications. Accordingly, the invention is further directed to the use of such membranes for plasma separation, plasma filtration, micro filtration, plasma therapy, haemodialysis and haemodiafiltration or cell filtration applications, respectively. The treated hydrophilic membranes show excellent biocompatibility, such as reduced platelet drop and decreased TAT levels.
