The operation of wastewater plants for advanced treatment involves considerable costs and resource use. Particularly the energy requirements (electric power) of wastewater treatment plants constitute a significant portion of the energy budgets of municipalities. Accordingly, great efforts have been undertaken in recent years to minimize the energy needs of treatment plants. These measures include:
In practice, these measures have demonstrated that with good planning and operationalization, significant potentials for the improvement of the energy efficiency of wastewater-treatment plants exist. However, the introduction of these methods also involves risks and disadvantages. In addition to the potential maximization of ammonium emissions and the deterioration of sludge stabilization, sedimentation behavior and the dehydration capacity of the sludge, there is also the danger of increased emissions of environmentally hazardous pollutants such as nitrite and laughing gas (N2O). The project has two essential targets:
