Abstract: The integrated reverse osmosis/pressure retarded osmosis system includes a first housing configured for pretreating feed brine, a second housing, a third housing configured for pretreatment of seawater, a first splitter positioned in communicating relation with the third housing, a first pump positioned in communicating relation with the first splitter, a fourth housing positioned in communicating relation with the first pump, a mixer positioned in communicating relation with the second housing and the first splitter, a first energy recovery system positioned in communicating relation with the second housing, a second energy recovery system positioned in communicating relation with the fourth housing, and a generator. The fourth housing configured for receiving pressurized seawater and producing desalinated product water by reverse osmosis. The second housing configured to receive feed brine from an oil production waste stream and decrease the salinity of the feed brine by pressure retarded osmosis.
