Results of the FY15 Brine Evaporation Bag (BEB) Technology Down-Select Testing

The Brine Evaporation Bag (BEB) recently participated in the Brine Concentrator Technology (BCT) Technology Down-Select (TDS). It was found that the BEB System is able to process ISS (International Space Station) Alternate Pretreat Brine at a rate high enough for ISS application as well as future deep space missions. The BEB System is also capable of processing the brine to a solid residue which will add to the stability and safety of storing the brine residue. The results of the BEB testing for the BCT-TDS will be presented in this paper.

Development of the Continuous-Fill Brine Evaporation Bag (BEB) System

The existing water recovery system on the International Space Station (ISS) is limited to 70 percent reclamation; consequently, long duration space missions are currently unfeasible due to the large quantity of water necessary to sustain the crew. The Brine Evaporation Bag (BEB) is a proposed system to supplement the existing water recovery system aboard the ISS and future deep space missions that can increase water recovery to 99 percent. The BEB project previously focused on the development of only the bag portion of the system. This paper focuses on the development of the BEB Evaporator. It will discuss the work to understand, optimize, and improve the entire BEB system while implementing a continuous-fill process. The results of that development and the advantages and limitations of the continuous-fill process will be presented.
