The. present study, Manipulated Osmosis Desalination (MOD) looks at a process based on the replacement of the conventional reverse osmosis (RO) process, in which the water from a pressurised solution is separated from the solutes (the dissolved material) by a two stage membrane process. The fIrst stage uses forward osmosis (Fa) that naturally drives out the fresh solvent from a concentrated salt solution by manipulating the osmotic energy potential through innovative use of osmotic agents. The second step involves nanofiltration (NF) separation to regenerate the OA and produce the clean water. Optimising the fIrst step to achieve the highest quality and quantity ofwater is the focus of this research. Experiments were conducted on a flat bed bench scale rig. Quantitative results are displayed on the effect of draw solution solute concentration and feed salinity on the quality and quantity of produced water. Further data is displayed on the effect of varying the flow and temperature ofthe draw and feed solutions.
