Ionic liquids (ILs) are potential drawing agents in forward osmosis (FO) due to their high ionicity, low vapor pressure and high solubility. A series of ILs were investigated as draw solutes for FO application and were compared with NaCl. Water (Jv )and reverse (Js) fluxes were evaluated using commercially available HTI-CTA membrane via FO and PRO modes. FO runs were conducted using 0.3M draw solution and DI water as feed. Results reveal that ILs like BMIM acetate, BMIM bromide and N4444 acetate were able to generate high Jv but with negligible Js. This demonstrates the potential of certain ILs as FO drawing agents.
