Benefits and Impacts Obsolescence Reduction Risk Reduction Safety Improvement Cost Reduction

1. Water Recycling System Area(s) of Significant Benefit Safety Performance Sustainability Operations Infrastructure • Description • Recycling water is of prime importance for long duration spaceflight including Shuttle emergency operations • Examine new low weight and power methods for water purification that eliminate impact of VOCs • Compare the performance of these new systems with current RO system based on weight, power, reliability, and lifetime Technologies and Capabilities • Evaluate new water separation and purification methods that do not use expendable materials, and then select the most efficient system, e.g. • Water purification with hydrated salts provides a convent method to eliminate VOCs. • Electro-Dialysis-Reversal provides an alternate method of purification. • Vacuum Distillation provides with a cold plate provides another method of purification. Benefits and Impacts Obsolescence Reduction Risk Reduction Safety Improvement Cost Reduction Process Improvement Other (Ultra-High Operations Improvement Reliability) Performance Enhancement • POC, Cost, Schedule and Maturity • TRL 3, Water Purification System • POC: Clyde Parrish, KSC, (321) 867-8763 • If a source of water is provided to the Shuttle, then one of the resources for survival always available. • Reduction in Category 1 Failure Rate of 0.5%
