Abstract
A reverse osmosis water purification system in which the concentrate water normally produced by the process is not disposed of by routing it to a drain line or otherwise, but is redirected to the main water supply. The system includes the well-known components of a reverse osmosis membrane, pre-filters which are installed ahead of the reverse osmosis membrane, and an appropriate tank to store the purified water. In addition, the system includes a pump and associated pressure sensing device for increasing the pressure of the incoming non-processed water to the reverse osmosis unit, and a pipe to carry the concentrate water from the reverse osmosis unit to the incoming main water supply, be it either a cold or hot water line. Additionally included is a one-way check valve in the concentrate water line, and a sensing device in the purified water storage tank to turn the pump off whenever the quantity of water in the tank exceeds a predetermined amount.
