ABSTRACT:
Water softened by ion exchange is pumped through a reverse osmosis material. The water treated by reverse osmosis may be stored under pressure and the reverse osmosis waste stream is recycled through the ion exchanger. The stored volume of water treated by reverse osmosis is approximately equal to or less than the volume of water that can be stored in the ion exchanger.
