Mitigation of Silver Ion Loss from Solution by Polymer Coating of Metal Surfaces, Part II
(2020 International Conference on Environmental Systems, 2020-07-31)
“Spacecraft potable water systems require a biocidal agent that effectively provides both immediate and residual disinfection over long periods of time. Ionic silver (Ag+) is a leading candidate for this application, but ...
Forward Osmosis Brine Drying
(46th International Conference on Environmental Systems, 2016-07-10)
The Forward Osmosis Brine Drying (FOBD) system is a membrane-based urine brine drying technology designed for use in microgravity. It has been evaluated by NASA for use on the International Space Station (ISS) to increase ...
Development of the Continuous-fill Brine Evaporation Bag (BEB) System
(46th International Conference on Environmental Systems, 2016-07-10)
The existing water recovery system on the International Space Station (ISS) is limited to 70% reclamation; consequently, long duration space missions are currently unfeasible due to the large quantity of water necessary ...
Results for the Brine Evaporation Bag (BEB) Brine Processing Test
(45th International Conference on Environmental Systems, 2015-07-12)
The recent Brine Processing Test compared the NASA Forward Osmosis Brine Dewatering (FOBD), Paragon Ionomer Water Processor (IWP), UMPQUA Ultrasonic Brine Dewatering System (UBDS), and the NASA Brine Evaporation Bag (BEB). ...
Evaluation of Brine Processing Technologies for Spacecraft Wastewater
(45th International Conference on Environmental Systems, 2015-07-12)
Brine drying systems may be used in spaceflight. There are several advantages to using brine processing technologies for long-duration human missions including a reduction in resupply requirements and achieving high water ...
Results of the FY15 Brine Evaporation Bag (BEB) Technology Down-Select Testing
(46th International Conference on Environmental Systems, 2016-07-10)
The Brine Evaporation Bag (BEB) has recently participated in the Brine Concentrator Technology (BCT) Technology Down-Select (TDS). The current understanding of the BEB System and how it would fit into a future space mission ...
Spectral Mass Gauging of Liquids with Acoustic Waves
(50th International Conference on Environmental Systems, 7/12/2021)
Mass gauging of liquids in reduced and zero gravity is one of the key technologies required to enable the next step in NASA�s space exploration program. Current mass-gauging technologies rely on modeling the state of liquid ...
BioMoSS: Biocidal MoS2 for Disinfection of Spacecraft Potable Water Systems
(49th International Conference on Environmental Systems, 2019-07-07)
It has been reported in the literature that few-layered, vertically-aligned molybdenum disulfide (FLV-MoS2) can produce biocidal agents for water disinfection with great effectiveness under visible light excitation. The ...
UV Chemistry and Mitigation of Siloxane
(48th International Conference on Environmental Systems, 2018-07-08)
The presence of dimethylsilanediol (DMSD) within the water supply of the International Space Station (ISS) causes issues with the Water Processing Assembly (WPA). The DMSD is believed to be a decomposition product of ...
An Assessment of the Water Extraction Capabilities of the Heat Melt Compactor
(44th International Conference on Environmental Systems, 2014-07-13)
The Heat Melt Compactor (HMC), a waste management technology developed at the NASA Ames Research Center, was designed to process waste generated aboard spacecraft. The device compacts, encapsulates and sterilizes the waste ...
