A numerical study of the non-stationary technological process of filtering lowconcentration solutions through a porous medium, proceeding in accordance with Darcy’s law taking into account the phenomena of colmatation and suffusion, was carried out. To determine the main parameters of the technological process and determine their ranges of change based on the developed numerical algorithm, computational experiments were carried out, the results of which made it possible to determine the degree of influence of solution contamination, technical and economic characteristics of the unit and its operating modes. The numerical calculations have established that when the suspension filtration time exceeds 450-500 hours, a sharp increase in hydraulic pressure in the layers of the unit column is observed, maximum accumulation of particles on the surface of the filter partition and a decrease in its pore space occurs and, consequently, the speed of fluid passage through the filter partition of the unit decreases. Then the process of detachment of particles deposited in the pore space of the filter partition begins. Analysis of numerical calculations showed that the technology of filtering the suspension and the initial concentration of the liquid supplied to the unit column play a significant role in selecting the filter operating modes.
