Claim 13:
14. A forward osmosis system, comprising:
a forward osmosis container comprising a semipermeable membrane dividing the forward osmosis chamber into a first chamber and a second chamber, wherein the first chamber intakes received water comprising a dissolved solute at an input parts per million level and provides a fluid output having an output parts per million level greater than the input parts per million level;
a draw solution water removal unit comprising a quantity of water and a quantity of draw solution solvent, wherein the draw solution solvent comprises a nonaqueous liquid having a boiling point greater than water; and
a condenser positioned above the draw solution water removal unit, the condenser configured to collect draw solution solvent vapor evaporated upward from the draw solution water removal unit, condense collected evaporated draw solution solvent vapor from a gaseous state into a liquid state thereby forming anhydrous liquid draw solution solvent, and provide the anhydrous liquid draw solution solvent to the second chamber;
wherein the second chamber provides a water diluted draw solution solvent to the draw solution water removal unit.
