Clean Water for Remote Locations

Marshall Space Flight Center engineers are working on creating the Regenerative Environmental Control Life Support System, a complex system of devices intended to sustain the astronauts living on the ISS and, in the future, sustain those who are blasting off to the Moon or Mars. The devices make use of the available resources, by turning wastewater from respiration, sweat, and urine into drinkable water. One of the devices that Marshall has been working on is the Water Recovery System (WRS). Marshall has teamed with long-time NASA contractor, Hamilton Sundstrand Space Systems International, Inc., of Windsor Locks, Connecticut. Hamilton Sundstrand, the original designer of the life support devices for the space suits, developed the Water Processor Assembly (WPA). It, along with the Urine Processor Assembly (UPA) developed by Marshall, combine to make up the total system, which is about the size of two refrigerators, and will support up to a six-member crew. The system is currently undergoing final test and verification. The WPA is tentatively scheduled for launch in 2008. Water Security Corporation, Inc., of Sparks, Nevada, owns the patents for the commercial use of this technology and has begun to offer it throughout the world-anywhere people need affordable, clean water. By combining the benefits of chemical adsorption, ion exchange, and ultra-filtration processes, Water Security Corporation's products yield safe, healthy, good-tasting water from the most challenging water sources, such as in underdeveloped regions where well water may be heavily contaminated with bacteria.
