Research on Reverse Osmosis Membranes for Purification of Wash Water at Sterilization Temperature (165Degrees F).

摘要

The goal was to develop viable reverse osmosis (RO) modules and systems of tubular design of approximately 80gpd capacity to recover wash water at sterilization temperatures. An 80gpd RO system was fabricated for recovering wash water at sterilization temperatures. The performance characteristics of ancillary components including particulate filters,gauges,meters,RO pump,accumulator carbon polishing column were verified by integrating the components into a suitable subsystem containing the RO module and life testing with wash water. The twenty tube module was used to define the total system and identify/correct some of the life limiting problems,and was tested under simulated mission conditions with wash water. It appears a viable 80gpd sulfonated PPO RO system for recycling wash water at sterilization temperatures and meeting the National Academy of Science (NAS) specifications is feasible.
