Development of the Process Control Water Quality Monitor for Space Station Freedom 911432

On-line monitoring of the effluent from the Space Station Freedom (SSF) water reclamation process determines acceptable quality for delivery to tanks supplying the crew's potable and hygiene water needs. TOC, pH, conductivity and iodine (biocide) are continuously monitored by the integrated, computer-controlled Process Control Water Quality Monitor (PCWQM). This paper describes the development of the system with emphasis on membrane gas-liquid separation and reagentless oxidation necessary to adapt standard TOC analysis to the unique requirements of the space environment.
