ABSTRACT:
A system which includes a separation element (11) employing semipermeable membrane material (17), which system is designed so that it can operate either in an RO mode to produce high quality water or in a PRO mode to generate power from two aqueous solutions of different salt concentrations. In a preferred embodiment, a rotary pressure transfer device (29) is included to transfer pressure from an outlet stream exiting the separation element to an inlet stream being supplied to the separation element.
