ABSTRACT:
A urine-water recovery system is described which provides efficient potable water recovery from waste liquids. The design allows use over extended durations such as encountered in space flights. The system has advantages such as low power consumption, compactness, and gravity insensitive operation. The system comprises a vacuum distillation system combining a hollow fiber polysulfone membrane evaporator with a thermoelectric heat pump and condenser. With the system of the present invention, water purified from urine can be produced at a rate of more than 0.5 kg/hr at a total system energy of less than 400 w-hr/kg.
