ABSTRACT:
A system for regulating a reverse osmosis system to obtain zero wastewater includes a fresh water supply, a reverse osmosis apparatus, a concentrate storage tank and a permeate storage tank, a concentrate solenoid valve and a permeate solenoid valve, a permeate heater, an institutional dishmachine and a control system. The reverse osmosis apparatus filters water from the fresh water supply into a concentrate rinse stream and a permeate rinse stream. The concentrate storage tank and the permeate storage tank are downstream of the reverse osmosis apparatus and receiving the concentrate rinse stream and the permeate rinse stream, respectively. The concentrate solenoid valve and the permeate solenoid valve control the flow of the concentrate rinse stream and the permeate rinse stream, respectively, from their respective storage tank. The permeate heater heats the permeate rinse stream to a predetermined temperature. The institutional dishmachine successively receives the concentrate rinse stream and the permeate rinse stream during a rinse cycle of the institutional dishmachine. The control system is operatively connected to the concentrate solenoid valve and the permeate solenoid valve and control flow of the rinse streams into the institutional dishmachine.
