Abstract

A desalination system is described. The system includes an optional pre-treatment unit to treat a feed stream with base and an oxidant. The system also includes two or three successive membrane-based purification units and precipitation units upstream of the membrane-based purification units. In combination, the membrane-based purification units may be: three nanofiltration-based units; two nanofiltration-based units and one reverse osmosis-based unit; one nanofiltration-based unit and one or two reverse osmosis-based units; one reverse osmosis-based unit operating at low pH and two reverse osmosis-based units operating at high pH. The concentrated effluent streams, or portions thereof, from the membrane-based purification units may be recycled to upstream portions of the treatment system. FIG. 1
