: This paper considers and solves the issues of taking into account the inverse eﬀect of process characteristics (liquid concentration and sediment contamination) on the environment characteristics (porosity, ﬁltration, diﬀusion, mass transfer, etc.) on the example of liquid puriﬁcation in magnetic and sorption ﬁlters. An algorithm for numerical- asymptotic approximation of the corresponding model problem solution is obtained, which is described by a system of non-linear singularly perturbed diﬀerential equations of the type “convection-diﬀusion-mass transfer”. Appropriate ratios (formulas) are eﬀective for optimizing the water treatment process and increasing the treatment system productivity as a whole (allow to determine the ﬁlter protective time, the ﬁlter size, etc.) in cases of convective predominance and sorption compo-nents of the corresponding process over diﬀusion and desorption which occurs in the vast majority of ﬁlter systems. On this basis, a corresponding com-puter experiment was conducted, the results of which show the proposed model advantages in comparison with classical.
