The paper is concerned that the intensification and efficiency of filtration processes for high solids concentration media are of widespread interest in many industries, such as oil production, oil refining, chemical, medical, and food. One of the reasons that impede filtration may be a high viscosity of the raw liquid. It is known that the filtration rate is inversely proportional to the viscosity; therefore, filtering viscous liquids will occur much slower. In addition, filtering high solids concentration media is associated with high costs for creating the driving force of the process, fast clogging of the pores of the filter material, the need for frequent regeneration of the filter material. Many high solids concentration media, such as mineral oils, polymer solutions and melts, highly polluted waters, tend to overgrow the flow area of the pore channel and, as a result, change their hydraulic characteristics due to the presence of helices and molecules of high molecular media, which makes filter regeneration difficult. Therefore, there is a need to replace the filter material with a new one. It is possible to intensify the filtration process by conducting preliminary preparation of the suspension, for example, by increasing the temperature of the medium or by decreasing the viscosity of the suspension by adding an appropriate solvent. In many technological processes, such methods are unacceptable. Relevant is the development and study of devices that allow you to increase the life of the filter material before regeneration, reduce energy costs to create the required pressure drop while maintaining the compactness of the device and the required cleaning fineness. The authors propose a method of filtering high solids concentration media and highly polluted liquids in...
