Experimental and Theoretical Study on Membrane Distillation Using Thermopervaporation

Water recycling systems have been studied at Hitachi using thermopervaporation technology for space use for about ten years. According to the studies this method is a good candidate for space application from the viewpoint of good water quality, system compactness and microgravity adaptability.

In this paper we discuss

1. (1)
   fundamental characteristics
2. (2)
   temperature distribution and
3. (3)
   effect of volatile substances of membrane distillation by thermopervaporation method from both theoretical and experimental point of view.
