Abstract:

High-Solids, Packed-Bed, Plug-Flow, Microbial Solid-Waste Processing Module for Space
Applications
Future space missions, such as Space Station Freedom, the Lunar Base, and Mission
to Mars, will involve prolonged life in space, placing new demands on closed loop
environmental control and life-support system technology. Regenerative systems, which
have already been developed for air and water management because of the magnitude
of resupply requirements, will also be required for solid waste management. In particular,
bio-regenerative systems become necessary as mission duration and resupply distances
increase. An innovative bioreactor will be developed incorporating a high-solids,
packed-bed, plug-flow design operating in micro- or partial-gravity environments.
The system provides high levels of biological stabilization of organic waste, while
minimizing reactor volume, residual solids storage, and energy input requirements.
This unique bioreactor design concept, specifically adapted for space applications,
overcomes equipment size and mass transfer limitations associated with biological
systems in space.
Applications include: modular industrial waste treatment for high-suspended-solids
streams; production of specialty chemicals from agricultural residues and biomass;
and micro-packaged waste treatment processes (marine, RV applications).
