Abstract:
On future long-term space missions, launch and resupply penalties associatedwith the storage and one-time use of the required quantities of water will be prohibitive;
consequently, space craft wastewater recycle systems are now under development.
Most system configurations are hybrid in nature--i.e., they are a combination of
several technologies, each optimized for the specific waste-
water stream to be treated. At the heart of most systems is a phase-change subsystem
that produces distillate. Another source of relatively clean water is the dehumidification
of the space craft cabin, which produces a "humidity condensate." These condensate
and distillate streams must be "polished" by a post-
treatment subsystem typically consisting of expendable sorption beds.
The goal is to develop a hybrid post-treatment subsystem consisting of a combination
of conventional sorption beds and a membrane module. The membrane module will act
to reduce the level of contaminants in streams entering the sorption beds and thus
reduce the rate of use of the sorption beds and the corresponding resupply penalty.
The goal of the project is to deliver a breadboard hybrid post-treatment subsystem
to NASA-JSC for testing.
