Abstract
Forward osmosis (FO) is a new membrane technology with the osmotic pressure of solution as the driving force. The water flux in FO process depends heavily on the temperature due to its effects on properties of solution and membrane and the interaction between them. In this study, the effect of temperature in FO process was investigated using numerical simulation and experiments. The results show that the FO water flux increases with temperature. In the presence of transmembrane temperature difference, the temperature of feed solution predominates the water flux over the temperature of draw solution, due to decreased solution viscosity and enhanced diffusion with elevated temperature. At different temperature profiles, water and heat flux increase with flow rate, resulted from the enhancement of mass and heat transfer within the depressed fluid boundary layer on the membrane surface.
