Full Description

As populations continue to increase and new water sources become scarcer, theneed for water reuse is realized. This technology is needed not only for growingurban centers but also for remote locations such as the summit of Pike's Peak,Colorado, or future Martian habitats. This paper describes a graywater reusesystem being developed for the new Summit House on top of Pike's Peak using someof the same unit processes NASA is testing for a closed-loop space habitat. Thissystem will help reduce traffic and labor at Pike's Peak by producing potablewater, treating graywater and reusing it on site. The current system consists ofhauling potable water to the Summit House in tanker trucks and hauling thegraywater back down the19-mile road to the Colorado Springs wastewater treatmentplant. NASA wants a long-term test of the reuse design at the Summit because ofthe harsh conditions faced at an elevation of 14,110 feet, such as lowtemperatures, low oxygen content and low pressures. The graywater reuse systemwill consist of an immobilized cell bioreactor, reverse osmosis membranes, anddisinfection. This project will provide a working water reuse design that will bebeneficial for use in future human space exploration and also in arid regions andremote sites here on Earth. Includes 13 references, table, figure.
