41 -- DESIGN, FABRICATION, AND PERFORMANCE VERIFICATION OF A SYSTEM TO REMOVE AIRBORNE TRACE CONTAMINANTS FROM A CLOSED CHAMBER. SOL 9BE3303517P DUE 032995 POC STEVE JANNEY, Tel:713-483-8505 Contracting Officer:LISA REA, Tel:713-483-8395 This announcement is for the design, fabrication, and performance verification of a trace contaminant removal system to ensure the health and safety of human test subjects for the duration of a test which will be conducted for 90 days in a 9050 cu.ft. internal volumn chamber. Four human test subjects will reside in the chamber and large scale plant growth experiments will be conducted. Organic contaminants from equipment offgassing, experiments and metabolic processes must be removed from the air, and levels of contaminants must be kept below spacecraft maximum allowable concentrations. Before fabrication, designs will be analytically demonstrated to remove all target contaminants. After fabrication, a performance verification test will be conducted. Designs that include regenerative systems are encouraged. --The Crew and Thermal Systems Division at NASA-Johnson Space Center will be conducting a 90 day chamber test of life support hardware. The test will be conducted in a chamber with 9050 feet cubed of internal volume. Inside the chamber, water from washwater, urine, and humidity condensate will be collected and purfified using physical chemical and biological processes. Carbon dioxide in the air will be removed, and oxygen will be generated from the recovered CO2. Four human test subjects will reside in the chamber throughout the test. Large scale plant growth experiments will be carried out during the test. --1 system to remove airborne trace contaminants from a closed chamber --NASA, Johnson Space Center --All items under the contract must be delivered by March 1, 1996. --This procurement is being conducted under NASA JSC midrange Test Program approved by the Office of Federal Procurement Policy on April 16, 1993.
