Simulation of reverse osmosis process: Novel approaches and development trends
Reverse osmosis is an essential technological separation process that has a large number of practical
applications. The mathematical simulation is significant for designing and determining the most effective modes of
membrane equipment operation and for a deep understanding of the processes in membrane units. This paper is an
attempt at systematization and generalizing the results of the investigations dedicated to reverse osmosis simulation,
which was published from 2011 to 2020. The main approaches to simulation were analyzed, and the scope of use of
each of them was delineated. It was defined that computational fluid dynamics was the most used technique for reverse
osmosis simulation; the intensive increase in using of molecular dynamics methods was pointed out. Since these two
approaches provide the deepest insight into processes, it is likely that they will further be widely used for reverse
osmosis simulations. At the same time, for the simulation of the membrane plant, it is reasonable to use the models that
required the simplest solutions methods. The solution-diffusion model appears to be the most effective and flexible for
these purposes. Therefore, this model was widely used in considering the period. The practical problems solved using
each of the considered approaches were reviewed. Moreover, the software used for the solution of the mathematical
models was regarded
