Ferric hydroacid & diamine complex as draw solute for forward osmosis (FO) desalination processes

Forward osmosis (FO) is being one of the recent technologies widely studied for desalination. FO mainly uses osmotic pressure gradient unlike reverse osmosis (RO) that uses hydraulic pressure gradient. So increasing the osmotic pressure is highly influencing the water flux in FO systems. A new type...
