The paper considers the possibility of using thefinite element analysis program to determine the designcharacteristics of a plate thin-layer module and comparestheoretical results with the simulation data. The mainpurpose of the study is to develop dependencies for anaccurate determination of the general parameters of atypical thin-layer plate module and apply them to a newtype of the module under study. In this paper, the standardcalculation formula for a conventional plate thin-layermodule is applied to determine its basic parameters.To solve the problem at hand, namely, determining thelimiting flow velocity in the module, the Stokes formula isused, taking into account the limiting Reynolds number.These methods are used to calculate the distance betweenthe plates of the module ( h ti), corresponding to the settling velocity of particles (hydraulic coarseness) U 0, as well as to visualize the settling velocity of particles at different design parameters of the module. Comparison of the obtained calculated results with theoretical values obtained duringsimulation analysis in ANSYS FLUENT program allows confirming the validity of the calculated formulas at the theoretical level.
