Modeling is done by MATLAB using the Solution-Diffusion model. At present work, the effect of two different parameters (temperature difference gradient and salt concentration) on different parameters is studied. Studying important parameters for temperature-driven reverse osmosis shows the direct effect of the temperature difference between the permeate-water part and the saline water part on different parameters. On temperature-driven reverse osmosis, the temperature difference between the permeate-water part and the saline-water part acts as a driving force. The penetration rate at each salt concentration rises by increasing the temperature difference between the permeate-water part and the saline-water part. The variations of different parameters versus temperature differences for two different saline water part concentrations (1 gr/lit and 0.35 gr/lit) are presented. For 1 gr/lit salt concentration and 1.5, 2.5, and 10.8 ^OC temperature difference between the permeate-water part and saline-water part, treated water penetrations are obtained 0.9, 0.9545, and 1.3118 l/m².h.bar respectively. Also, for 0.35 gr/lit salt concentration and 1.5 and 9.3 ^OC temperature difference between the permeate-water part and saline-water part, treated water penetrations are obtained at 0.917 and 1.167 l/m².h.bar respectively.
