  • Patent number: 11608285
    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.

  • Patent number: 11602718
    Abstract: This specification describes membrane based filtration and softening systems and methods. A system has a microfiltration or ultrafiltration (MF/UF) membrane unit upstream of a nanofiltration or reverse osmosis (NF/RO) membrane unit, optionally with no intermediate tank. In some cases, the system and method may be used with feed water provided at municipal line pressure to the membranes. NF/RO permeate is collected in a tank and then pumped to a header. Treated water may be drawn from the header for use or recycled to the system, for example to backwash or flush one or both of the membrane units. In a combined process, NF/RO permeate flushes the feed side of the NF/RO unit and then backwashes the MF/UF unit. In another process, the MF/UF unit and NF/RO unit are filled with NF/RO permeate before being placed in a standby mode.

  • Patent number: 11577205
    Abstract: A housing of a separation apparatus includes therein a zeolite membrane complex. A sheath includes therein the housing. A fluid supplied to the inside of the housing has a temperature higher than the temperature around the sheath. A second exhaust port is used to exhaust a permeated substance that has permeated through the zeolite membrane complex in the fluid to the outside of the housing. The permeated substance exhausted from the housing can be led into an exterior space between the sheath and the housing through the second exhaust port and can be exhausted through an exterior exhaust port. At least part of the zeolite membrane complex is included in an inter-port space surrounded by the sheath, the second exhaust port, and the exterior exhaust port. This structure reduces energy required for fluid separation performed under high temperatures.
