Abstract
A system for regulating a reverse osmosis system to obtain zero wastewater. A reverse osmosis apparatus filters water from the fresh water supply into a concentrate rinse stream and a permeate rinse stream. A concentrate storage tank and a permeate storage tank are downstream of the reverse osmosis apparatus and receive the concentrate rinse stream and the permeate rinse stream, respectively. A concentrate solenoid valve and a permeate solenoid valve control the flow of the concentrate rinse stream and the permeate rinse stream from their respective storage tank. An institutional dishmachine receives the concentrate rinse stream and the permeate rinse stream during a rinse cycle of the institutional dishmachine. A 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.
