Vapor Compression Distillation Urine Processor Lessons Learned from Development and Life Testing 1999-01-1954

Vapor Compression Distillation (VCD) is the chosen technology for urine processing aboard the International Space Station (ISS). Development and life testing over the past several years have brought to the forefront problems and solutions for the VCD technology. Testing between 1992 and 1998 has been instrumental in developing estimates of hardware life and reliability. It has also helped improve the hardware design in ways that either correct existing problems or enhance the existing design of the hardware. The testing has increased the confidence in the VCD technology and reduced technical and programmatic risks. This paper summarizes the test results and changes that have been made to the VCD design.
