OG exemplary drawing
 
1. A method for removing one or more solutes and water from a solution, the method comprising:
introducing a feed solution having at least one permeable solute into a first side of a forward osmosis system;
circulating a draw solution through a second side of the forward osmosis system, the draw solution having one or more solutes and a concentration of the at least one permeable solute that is lower than a concentration of the at least one permeable solute in the feed solution;
generating a diluted draw solution in the second side of the forward osmosis system, the diluted draw solution having a higher water concentration and higher at least one permeable solute concentration than the draw solution;
producing a product stream including a concentrated feed solution from the first side of the forward osmosis system, the concentrated feed solution having a lower water content and a concentration of the at least one permeable solute that is lower than the concentration of the at least one permeable solute in the feed solution;
regenerating the draw solution from the diluted draw solution.
