EXTRACTION PROCESS OF WASTEWATER TREATMENT AND DEVELOPMENT OF PRINCIPLE FLOWCHART.

The possibilities of the extraction process for wastewater treatment, oil and oil products pollution have been studied, and principle flowchart has been developed. Physical and chemical problems accompanying the extraction process are analyzed. Some features of the extraction process are considered and a principle flowchart of wastewater treatmentis developed. Liquid-phase extraction processes are carried out in various apparatuses, mixing devices, and in some cases using membrane technologies. It is shown that the processes of liquid-phase extraction occurring in mixing devices are complicated by many physical phenomena, for example, colescence and crushing of extractant drops, separation and stratification of extract and refined sugar, accompanying various effects (Marangoni effects, Fasi effect) and interfacial mass transfer. To improve the parameters of interfacial transfer, in addition to various ones, the most acceptable is to increase the interfacial surface. In liquid phase extraction processes, the main factor is mass transfer between two immiscible liquids. Liquid extraction of organic compounds and oil from wastewater is a mass transfer process that occurs in an interfacial film and is carried out by dispersing the extract - it will dissolve in an aqueous medium and extraction in an interfacial film, characterized by diffusion transfers of the corresponding components to the interfacial surface.
