A numerical study was conducted based on the proposed mathematical apparatus of non-stationary technology for filtering a low-concentration solution through a porous medium, taking into account the process of colmatation and suffusion, based on Darcy’s law and convection-diffusion equations. To determine the main parameters of the tech nological process and determine their ranges of change based on the developed numerical algorithm, experiments were carried out on a computing system, using which the main parameters that significantly affect the process as a whole were determined, and their ranges of change depending on the degree of contamination of the solution and the tech nical and economic characteristics of the unit and its operating mode. The numerical calculations have established that when the filtration time of the suspension exceeds 150-200 hours, a sharp increase in hydraulic pressure in the layers of the unit column, maximum accumulation of particles on the surface of the filter partition and a decrease in its pore space are observed and, consequently, the speed of passage of liquid through the f ilter partition of the unit decreases. Consequently, the process of separation of particles settled in the pore space of the filter partition begins. Analysis of numerical calculations showed that the technology of filtering the suspension of the initial concentration of liquid supplied to the unit column plays a significant role in selecting the filter operating mode.
