Water Walls Life Support Architecture

摘要

Water Walls is a concept for a largely passive life support system, centered on the application of forward osmosis membranes to replace the large, complex, and failure-prone machines than now perform these functions. In the present integration, these functions include: Block 1) humidity control, Block 2) volatile organic compound destruction, Block 3) use of algae and cyanobacteria for CO_2 removal, O_2 production, and nutritional supplement, and Block 4) Urine and graywater processing, solids/blackwater treatment, and energy generation. This paper presents the early development work on the Water Walls Life Support Architecture. It describes the initial concepts and shows how the Water Walls team's efforts have matured beyond this baseline.
