ABSTRACT:
A method of water purification including the steps of passing source water through at least one reverse osmosis unit to produce a product water and reject water, directing the product water from a reverse osmosis unit into the dilution stream of a continuous electrodeionization unit, directing the reject water from the first pass reverse osmosis unit through a softening unit to produce softening unit output water with fewer hardness elements than the reject water from the first pass reverse osmosis unit, directing the softening unit output water into a concentrate stream of the continuous electrodeionization unit, and wherein the continuous electrodeionization unit further purifies the water from the dilution stream to produce purified water.
