“…which is the well-known result obtained for ideally-semi-permeable barrier layers20. From equation (15) we can obtain this inverse relationship between the Péclet number in the support (or any other parameter directly proportional to the trans-membrane volume flow) and the driving force of the process (parameter F ).…”

“…To design membranes for various FO processes, it is important to understand critical structure-performance relationships, especially with respect to mass transfer. This has led to a number of theoretical transport models to predict osmotic water flux coupled with reverse salt flux across FO membranes [21,23,[38][39][40][41][42][43][44][45][46][47][48][49][50]. Many of these models have been used to predict the severity of concentration polarization (CP), a mass transfer phenomenon that reduces osmotic driving force.…”

“…In the period under consideration, this model was applied to the description of the RO process for both water solutions [23][24][25] and organic systems [21,22]. Also, it has been used for the development of hybrid models [26] and the theoretical analysis of the mass transfer through the membrane [27]. Furthermore, the modifications of the solution-diffusion model were proposed.…”

“…Furthermore, the modifications of the solution-diffusion model were proposed. They consider the concentration polarization [24], the sorption equilibrium between membrane material and organic matter [22], and nonlinear relationships among the mass transfer coefficient and the operation parameters of the process [26,27].…”
