Water Recovery of Reverse Osmosis Brine and Pretreated Urine with an Air Evaporation Subsystem
This paper focuses on an Air Evaporation Subsystem component of the Water Recovery System being developed at the Johnson Space Center in the Crew and Thermal Systems Division. Specifically, the focus is on the design and testing of the next generation of Air Evaporation Subsystem Engineering Development Unit built after the Lunar-Mars Life Support Test Project Phase III 91day test. The primary objective of testing this next generation Air Evaporation Subsystem was to demonstrate its performance as a Reverse Osmosis brine treatment subsystem by looking at the condensate quality produced from Reverse Osmosis brine and the power required to process the Reverse Osmosis brine. The secondary objectives were to develop optimal operating conditions, to optimize the use of a consumable wick and to retain as much operational data as possible through instrumentation.
