There are many different processes running in wastewater treatment plants and sewerage systems that are subject to continual changes. In order to achieve an optimised regulation or control system, it is necessary to continuously monitor the various processes. New technical developments in metrology, such as online measuring devices, provide a continuous stream of data that has to be monitored, analysed and processed.

Nowadays monitoring systems are used as part of the control systems at wastewater treatment plants. The latter allow various measurement values to be displayed in the form of time diagrams and are easily monitored by plant personnel. Developments in modern sensor technology lead one to expect that in the next few years the number of variables to be monitored will greatly increase. However, by comparison, there is fewer and fewer staff available that can carry out monitoring duties. In this situation an automatic monitoring system can guarantee safe operation and is of assistance when it comes to exploiting the potential for optimisation. The aim is to extract information from the data arising and to analyse it automatically with regard to system changes and malfunctions within the subordinate process. As a result, only a few condensed and easily understood statements concerning the state of the process are then provided, which enable the staff to find out about the current situation with regard to the process at a glance.
Such processes are developed within the GECO►C team and studied when put to practical use. PCA (Principle Component Analysis), for example, or other statistical or cluster-forming algorithms are used in this connection.
