Nitrification and denitrification processes are very sensitive to temperature changes below 10 °C. Because of severe eutrophication problems in e.g. Northern Europe Nitrogen removal must be kept throughout the winter. To aid in the design and optimization of treatment plants a dynamic temperature model has been developed. The major findings is that the temperature variation is very dependent on local wind conditions. The model can be used in the design process to minimize factors causing temperature drops during cold weather periods.
