Mass balances and kinetic parameters for nitrification are essential tools for a rational design of aerobic biological treatment systems. These were determined in lab scale investigations and applied on representative assessment cases for mid- and long-term variations of nitrogen. Thus, with the help of dynamic simulation, criteria for the design of highly efficient biological treatment of textile wastewater were developed, which were also evaluated in economic considerations. Combined treatment of textile and domestic wastewater has shown to be advantageous, because it provides a constant basic nitrogen load. Furthermore, the choice of a sufficiently high sludge age is recommended to reach a reliable treatment system and a simple operation.
