Desalination by osmosis--reverse osmosis couple.
Water is separated from brines by a semipermeable membrane. Water flows by osmosis across the membrane into a sealed chamber where it creates pressure. This pressure is transmitted by a water-immiscible liquid piston to a second chamber where it effects reverse osmosis. Water-removal rates are calculated.
