摘要： The method of solvent recovery includes using a plurality of solvent recovery units to recover solvent from a dilute solution. The solvent recovery units can include a plurality of reverse osmosis or forward osmosis membrane systems arranged in series. For reverse osmosis, at least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate of that unit to provide a mixed permeate. The mixed permeate is then passed successively to the permeate side of each preceding reverse osmosis unit in the series. For forward osmosis, a draw solution is passed sequentially from the permeate side of each unit to the permeate side of the preceding unit. The draw solution may be prepared by concentrating part of the concentrate stream by evaporation and recycling it back as a draw solution.

摘要： The method for purifying liquids purifies a saline liquid, e.g., salt water, using a plurality of first phase reverse osmosis (RO) units and at least one final phase reverse osmosis unit. The plurality of first phase reverse osmosis units are arranged in series. At least some of the concentrate in a last reverse osmosis unit of the series is recycled back to the permeate or output side of that unit to provide a mixed permeate. The mixed permeate is then passed successively to the permeate side of each preceding reverse osmosis unit in the series. This increases the salt content of the liquid in the permeate side of each phase, thus reducing the concentration differential across reverse osmosis membranes of the first phase reverse osmosis units.
