ABSTRACT:
A reverse osmosis purification system is operated on a ratio of approximately 1 to 1 to 2 to 1 waste water to product water. The system uses the cold water outlet and a cold water path which extends through the RO membrane to remove non-migrating particles trapped on the outside of the reverse osmosis membrane to remove salts from the membrane and allow to prolong the life of the membrane despite low brine to pure water ratio.
