Abstract: A method for providing controlled salinity water for enhanced oil recovery begins by raising the pressure of, and then splitting, a treated seawater feed into two supply streams which are then processed in parallel. One supply stream is passed thorough a nanofiltration membrane system while the other is passed through a reverse osmosis membrane system.
