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.

“…Обратный осмос -это управляемый давлением мембранный процесс разделения, который широко применяются в промышленности [19]. Мембраны обратного осмоса могут быть использованы для обессоливания и удаления растворенных органических веществ при одновременном снижении общего органического углерода, химического потребления кислорода (ХПК) и биологического потребления кислорода (БПК) [16].…”

The article discusses in detail the membrane processing of complex systems, reverse osmosis (RO) and electrodialysis (ED) membranes. Currently, the development of industrial wastewater treatment technologies is of great interest to many researchers. This is due to the fact that the food, pharmaceutical and chemical industries are becoming increasingly important in our lives, while exacerbating one of the most serious environmental problems, environmental pollution from industrial wastewater, which contains harmful substances in high concentrations. This study is devoted to the analysis of a new technology for the extraction of complex components from industrial wastewater, combining reverse osmosis and electrodialysis. Reverse osmosis systems are pressure controlled membrane separation processes. In contrast, an electrodialysis system is an electrochemical process that is commonly used industrially under normal atmospheric pressure. However, such membrane processes have a significant drawback, the working membranes are contaminated with suspended substances in the wastewater and lose their activity. Therefore, to maintain the activity of the membranes for a long time, it is necessary to pre-treat wastewater by removing suspended solids. The analysis of the recovered components opens up new perspectives for the recovery of industrial wastewater. There is a wide range of methods for pretreatment of water for reverse osmosis and electrodialysis. Ultrafiltration (UF) followed by reverse osmosis is an important process for separating organic and inorganic compounds from wastewater. This article discusses some of these methods. In conclusion, it should be noted that electrodialysis demonstrates remarkable technical advantages in the treatment of concentrated solution after RO.
