Hyperfiltration Wash Water Recovery Subsystem - Design and Test Results

The Hyperfiltration Wash Water Recovery-Subsystem is considered the most promising water recovery process for the large quantities of wash water needed for a Space Station. A preprototype Hyperfiltration Subsystem has been developed by Lockheed Missiles and Space Corporation (LMSC) to satisfy projected wash water recovery requirements of 10.9 Kgms/hr (24 lbs/hr) utilizing a hyperfiltration module consisting of cintered metal tubes having a polymeric filtration layer. Two hyperfiltration module designs, manufactured by Abcor, Inc. and Carre, Inc., are currently being evaluated at NASA JSC. This paper presents a description of the preprototype subsystem design and important design features, configuration, module test results comparisons, and recommendations for future development and testing.
