Abstract

In the present study modeling and formulation of the thermal gradient effect on reverse osmosis process for evaluation treated water penetration and water production are studied. 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.
