摘要：At least 70% of WWTP of small capacity in Russia include biofilters, that's why development of new technologies for treatment and methods of reconstruction are the points of great interest This abstract describes the methods and techniques of biofilters reconstruction to achieve desired water quality. The presence of biogenic compounds (NH4, PO4) in the water body are one of the causes of eutrophication. The article considers the methodology of modeling processes of wastewater treatment in the biofilters: The results of sanitary - chemical researches and researches of the formed biomass are given. Based on the obtained data, laboratory models for hydraulic modeling and simulation of denitrification-nitrification processes on biofilters were developed. Modified mathematical model for calculating the height of the biofilters received specific mathematical dependences for the studied feed material.
