Claim 11:
12. The system of claim 1, wherein the first membrane and the second membrane have a first set of electroosmotic and osmotic transport properties and the third membrane has a second set of electroosmotic and osmotic transport properties that are different from the first set of properties, the system further comprising:
a third reservoir defined by the second membrane and a fourth membrane having the first ion exchange type and the second set of electroosmotic and osmotic transport properties, wherein a second portion of the brine stream is input to the third reservoir;
a fourth reservoir defined by the fourth membrane and a fifth membrane having the second ion exchange type and the second set of electroosmotic and osmotic transport properties, wherein a third portion of the brine stream is input to the fourth reservoir;
a second effluent stream comprising the solvent and a fifth salt concentration output from the third reservoir, wherein the solvent is moved from the first and fourth reservoirs to the third reservoir via electroosmosis and forward osmosis; and
a solvent stream comprising a sixth salt concentration output from the fourth reservoir.
