Abstract

In one aspect, the invention provides a RO system (20) comprising an energy recovery device (ERD) (34). The system comprises a water intake pump (22) to provide a feed water; a pre- treatment section (24) to pre- treat the feed water to provide a pre- treated water; a membrane section (26); an optimizer module (42) to estimate a value for at least one operating variable associated with at least one decision variable, wherein the decision variable is associated with at least one objective constraint; and a control module (48) for operating the RO unit at the estimated value of the at least one operating variable. The RO unit is characterized by a total energy consumed, wherein the energy recovered by ERD impacts the total energy consumed, and the at least one decision variable is selected from a group consisting of flow rate at high pressure pump (28); pressure at high pressure pump outlet; flow rate at re - circulation pump (40); pressure of low pressure brine reject stream; or combinations thereof.
