Abstract
Provided herein is forward osmosis-based water purification process, that includes contacting a solution of a soluble draw agent with a dehydrated insoluble draw agent, separating the now hydrated insoluble draw agent from the now concentrated draw solution, and exerting a stimulus on the hydrated insoluble draw agent for extracting water therefrom, thereby regenerating a dehydrated insoluble draw agent, wherein the osmotic concentration (osmolality) of the insoluble draw agent is greater than the osmotic concentration of the diluted draw solution, and the insoluble draw agent is impermeable to the soluble draw agent.
