The cascaded distiller CD5 is a 5-stage, rotary vacuum distiller developed jointly by Honeywell International (USA) and Thermodistillation Co. (Kiev, Ukraine) for processing of human urine and other streams of waste water onboard a spacecraft during long-duration missions. Initial performance testing of the first model of the distiller CD5-1 was conducted at the Thermodistillation laboratory in Kiev in 1999. Results of testing demonstrated superior performance of the machine, but also indicated that performance could be improved. This paper reports on performance of the next generation of the distiller, CD5-2, which is an improved model of the cascaded distiller CD5-1.
