Abstract: The procedure of the utilization of dynamic simulation programs for design and upgrading of biological processes of nitrogen removal is presented. An upgrading of nitrification reactor to predenitrification system is illustrated. Design calculations were performed according to steady-state design practice. An optimization procedure for calculation of volume of denitrification reactor was developed. Minimizing of differences between required and calculated values of denitrified nitrogen is the merit of the applied method. Dynamic simulations were used for optimization of the dimensions of nitrification and denitrification reactors with regard to effluent standard values and fluctuations of wastewater flow and composition. A method for evaluation of dynamic simulation of results with respect to dynamic nature of wastewater effluent standards is suggested.
