Application of membrane technologies in industrial wastewater treatment

Introduction. Modern methods of application of membrane technologies in industrial wastewater treatment are considered. The problem of reducing the negative impact on the environment by increasing the efficiency of treatment facilities is the most urgent at the moment. Recently, membrane technologies of wastewater treatment are becoming more and more demanded for their inclusion in the existing technological schemes of industrial enterprises located all over the world.Materials and methods. Examples of technologies used in the dairy industry, oil and fat industry, automobile manufacturing, electric power industry, and tanning industry were studied. Domestic and foreign sources were analyzed.Results. As a result of the work carried out, preference is given to technological schemes that allow to create waste-free production, namely, the reuse of treated water in the technological processes of the enterprise, which contributes to improving the efficiency of treatment facilities. The application of membrane technologies makes it possible to achieve the goals set to reduce the negative impact on the environment, but at the same time this technology is not without disadvantages.Conclusions. The technology strongly depends on the specific composition of wastewater and the existing technological scheme of treatment. However, based on the reviewed examples in various industries, this technology is becoming more and more widespread and shows excellent results in reducing the negative impact of industrial effluents. The technology of membrane filters for creation of waste-free production should be further considered and developed.
