Abstract
A system for reverse osmosis, RO, and for pressure retarded osmosis, PRO, includes: a RO subsystem () with a high-pressure RO chamber () and a low-pressure RO chamber () separated by a RO membrane (), the high-pressure RO chamber () having a RO feed inlet () and a brine outlet () and the low-pressure RO chamber () having a permeate outlet (); a PRO subsystem () with a high-pressure PRO chamber () and a low-pressure PRO chamber () separated by a PRO membrane (), the high-pressure PRO chamber () having a draw inlet () and a draw outlet () and the low-pressure PRO chamber () having PRO feed inlet () and a PRO feed outlet (); an induction motor () having a stator and a rotor, wherein the rotor is mechanically connected to an input shaft of a hydraulic pump () configured for providing a feed solution to the RO feed inlet () and to an output shaft of a hydraulic motor () configured for receiving a draw solution from the draw outlet (). The invention further discloses a method for operating such system for RO/PRO and to the use of such system.
