Abstract
While forward osmosis (FO) processes have undergone great technological advancements, the control of reverse solute diffusion and the effective recovery of draw agents remain major challenges for the systematically sustainable and economically feasible use of FO. This article reviews polymer hydrogel- and nanoparticle-based draw agents that can (i) induce a high osmotic pressure, (ii) result in insignificant reverse diffusion of solutes, and (iii) be effectively regenerated by simple separation methods.
