Coiled Brine Recovery Assembly, Year 2 (CoBRA)

After the Coiled Brine Recovery Assembly (CoBRA} undergoes necessary further development, the technology could be integrated into the International Space Station (ISS) life support system as a brine processor. This has the potential to recover 575 pounds of water per year from brine. This represents roughly $10M per year in savings on water resupply costs. While the primary function of the CoBRA is to recover water from concentrated wastewater brines generated by a primary processor, the CoBRA may be able to function as a primary processor itself. Current state-of-the-art primary processors rely on rotating drums, pitot pumps, lobe compressors, and other sensitive machinery for operation. This equipment has a history of becoming fouled due to solids precipitation. In the case of a failure of the primary processor, the CoBRA could serve as a backup, providing dissimilar redundancy to ensure crew survival. Upon successful demonstration of a proof-of-concept evaporator, Advanced Exploration Systems (AES) will provide funding for further development. This will lead to infusion of CoBRA technology into an integrated closed-loop life support system architecture. The CoBRA will then be poised to play a key role in a future ground-based integrated life support systems test, and an eventual ISS detailed test objective (DTO). After a successful DTO, CoBRA could be integrated into the International Space Station (ISS) life support system, with the potential to recover 575 pounds of water per year from brine. This represents roughly $10M per year in savings on water resupply costs. Leveraging the extensive technology maturation and testing accomplished through a DTO, the CoBRA will then be ready for use by future deep-space exploration programs. Coiled Brine Recovery Assembly (CoBRA) technology also has the potential to be used for water recovery from contaminated wastes in the chemical, nuclear, and hydraulic fracturing industries.
