Next Generation Life Support Project Status
(44th International Conference on Environmental Systems, 2014-07-13)
Next Generation Life Support (NGLS) is one of more than 20 technology development projects sponsored by NASA’s Game Changing Development Program. The NGLS Project develops selected life support technologies needed for ...
Synthetic Biological Membrane Forward Osmosis Trade Study
(48th International Conference on Environmental Systems, 2018-07-08)
This document provides a trade study for the Synthetic Biological Membrane (SBM). The objective is to compare the SBM technology against the current state of the art in spacecraft water recycling. The primary advantage ...
Forward Osmosis Brine Drying
(45th International Conference on Environmental Systems, 2015-07-12)
The Forward Osmosis Brine Drying (FOBD) system is based on a technique called forward osmosis (FO). FO is a membrane-based process where the osmotic potential between brine and a salt solution is equalized by the movement ...
Space and Industrial Brine Drying Technologies
(44th International Conference on Environmental Systems, 2014-07-13)
This survey describes brine drying technologies that have been developed for use in space and industry. NASA has long considered developing a brine drying system for the International Space Station (ISS). Possible processes ...
Continued Development of the Brine Evaporation Bag
(44th International Conference on Environmental Systems, 2014-07-13)
The Brine Evaporation Bag (BEB) is a membrane based bag system for the dewatering of brine. Previous studies showed the ability of the BEB to dewater brine at low temperatures with a 96% mass reduction. Additionally, a ...
Progress and Direction of the Forward Osmosis-Cargo Transfer Bag Concept for 2013
(44th International Conference on Environmental Systems, 2014-07-13)
The Forward Osmosis - Cargo Transfer Bag (FO-CTB) is a modified cargo transfer bag (CTB) with an embedded functional water treatment element, based on a forward osmosis (FO) membrane. CTBs are used to deliver small items ...
The Utilization of Urine Processing for the Advancement of Life Support Technologies
(44th International Conference on Environmental Systems, 2014-07-13)
The success of long-duration missions will depend on resource recovery and the self- sustainability of life support technologies. Current technologies used on the International Space Station (ISS) utilize chemical and ...
Optimization of the Distiller Calcium Limiter (DCaL) System for Calcium Removal in Spacecraft Wastewater
(44th International Conference on Environmental Systems, 2014-07-13)
The Distiller Calcium Limiter (DCaL) system removes calcium scale precursors from spacecraft wastewater. Previous research has indicated that the DCaL system successfully removes calcium, preventing the formation of calcium ...
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 ...
