It's had been presented methods of sewage treatment, a mathematical model of the selected process. The purpose of modeling is to determine the optimum process conditions, managing them on basis of a mathematical model and transfer the results to an object. A complete mathematical model includes a description of the relationships between the main process variables in steady-state regimes (static model) and in time from one mode to another (dynamic model). The solution of the model under consideration consists in selecting the appropriate equations for describing the operating mode, checking the restrictions on the input and output parameters, calculating the objective function. Variable input parameters include granulometric composition and sorbent layer height. The adsorption capacity of the adsorbents used, the quality and composition of the initial wastewater, the speci ed productivity and the degree of puri cation are the unvariable input parameters of the process. Since the regeneration of the zeolite in the process is not envisaged, then in solving the mathematical model we were satis ed with the selection of the corresponding equations for describing the operating mode.
