Silver Foam: A Novel Approach for Long-Term Passive Dosing of Biocide in Spacecraft Potable Water Systems � Update 2021
(50th International Conference on Environmental Systems, 7/12/2021)
A spacecraft water disinfection system suitable for extended length space exploration should prevent or control the growth of microbes, prevent or limit biofilm formation, and prevent microbiologically influenced corrosion. ...
Unit Operation Performance Testing of Cascade Distillation Subsystem
(44th International Conference on Environmental Systems, 2014-07-13)
The Cascade Distillation System (CDS) is a waste water recovery technology being developed under NASA’s Advanced Exploration System (AES) water recovery project. The Cascade Distiller (CD) is the principal component of the ...
Development of an Electrolytic Silver Biocide Dosing System for Use in a Spacecraft Potable Water Bus
(47th International Conference on Environmental Systems, 2017-07-16)
Maintaining microbial control in spacecraft potable water storage and delivery systems is a significant challenge for long-duration human space exploration. Simple, robust biocide systems are needed that are capable of ...
Literature Review of Disinfection Techniques For Water Treatment
(2020 International Conference on Environmental Systems, 2020-07-31)
Water treatment is a developing concern, both terrestrially and in spacecraft, as exploration missions extend in time and distance. Current biofilm control is limited for long-term applications. To optimize biocides for ...
A Two-Stage Biological Reactor for Treatment of Space Based Waste Waters
(48th International Conference on Environmental Systems, 2018-07-08)
Previous works on Membrane Aerated Biological Reactors (MABR) CoMANDR 1.0, CoMANDR 2.0, and R-CoMANDAR have demonstrated their ability to stabilize various space based waste streams over operating periods of ~1 year. ...
Long Term Biological Treatment of Space Habitation Waste Waters in a One Stage MABR: Comparison of Operation for N and C Oxidation With and Without Simultaneous Denitrification
(48th International Conference on Environmental Systems, 2018-07-08)
Aerobic biological stabilization has been previously demonstrated for full size MABR’s (CoMANDR 1.0, CoMANDR 2.0, and R-CoMANDR) over operating periods of ~1 year. These systems have successfully treated a variety of ...
Sodium Chloride Removal from International Space Station Wastewater Brine to Generate Plant Fertilizer
(50th International Conference on Environmental Systems, 7/12/2021)
Water is a critical resource for human exploration beyond low earth orbit. There are two general mechanisms for wastewater recovery. The current practice on the International Space Station (ISS) is vapor compression ...
Development of a Foam Based Capillary Driven Brine Residual in Containment (BRIC) Processor
(47th International Conference on Environmental Systems, 2017-07-16)
One of the goals for the AES Life Support System (LSS) project is to achieve 98% water loop closure for long duration human exploration missions beyond low Earth orbit. Critical to this goal is development of a brine water ...
Update on Feasibility of UV LEDs in a Spacecraft Wastewater Tank Application
(2020 International Conference on Environmental Systems, 2020-07-31)
As the National Aeronautics and Space Administration (NASA) expands its scope and begins to venture into long-duration manned space flights, the function and maintenance of spacecraft water systems becomes increasingly ...
Considerations for Development of a Total Organic Carbon Analyzer for Exploration Missions
(48th International Conference on Environmental Systems, 2018-07-08)
Monitoring the Total Organic Carbon (TOC) in spacecraft potable water will be of major importance in long-duration human space exploration. In-flight analysis of potable water produced from a regenerative water processor ...
