On the basis of the obtained results, consider the issue of increasing the efficiency of their work, in particular, using biochemical methods of cleaning fixed biocenosis (biofilm). On the basis of the analysis of research results, engineering recommendations and calculations aimed at increasing the efficiency of such reactors will be developed. The research will also be aimed at the further development of the theoretical foundations of the processing of man-made water suspensions, which contribute to the active removal of harmful impurities, at the creation of calculation methods to ensure reliable forecasts of changes in the characteristics of biofiltration in stable and dynamic conditions, at the substantiation of rational working modes, technological and design parameters to ensure maximum return from the operation of biological and physical and chemical water treatment facilities. popup.description2 Substantiation, development and improvement of mathematical models describing the processes of mass transfer in bioreactors and biofilm and the processes of formation of its structure, in particular, thickness under stationary and non-stationary conditions. Formulation and solution of the mathematical problem of sediment filtration with linear kinetics of mass transfer and variable concentration of impurities for three schemes of supplying aqueous suspension when loading a rapid filter. Development of a method for technological modeling of suspension clarification and estimation of the duration of filtration for two types of two-flow filter and three-flow filter.
