The job of a sewerage system consists in the rapid, deposit-free onward transmission of wastewater to the wastewater treatment plant, whilst at the same time avoiding damage due to flooding. In the past, sewerage systems were mostly statically operated and, as a result, were not able to react to the natural fluctuations in outflow events.
Due to increasing economic and environmental aims, the trend towards the dynamic management of sewerage systems dealing with combined wastewater is gaining acceptance.
The Operating Range of the GECO ► C Working Team:
Through the use of intelligent control systems the optimum use of storage and overflow capacities within the sewerage system is made possible. In this way, the combined wastewater discharge rate can be considerably reduced so that building extensions is, in many cases, unnecessary.
Ideally, a consideration of the sewerage system will include the operation of the wastewater treatment plant. Thus, not only a hydraulic approach but also one that is load-dependent can be pursued.
It must be stressed in this situation that our team already takes measurement within the sewerage system in order to ensure a steady inflow rate to the wastewater treat
ment plant. In this regard, permissible outflow concentrations from the plant, which may refer to COD or ammonium values, for example, represent the crucial aspects.
