Supervision system for SBR's

Within the framework of the project, the local database in at the INRA, Narbonne, France while the decentralized one is at SPES location, Fabriano, Italy. The supervision system is supposed to act on the long term, the immediate decision and optimal functioning being, by definition, left to the control system (cf. WP5). The role of the supervision system is thus rather to decide on the long term if the actual control algorithm works well.

The decision was then taken to analyse the state of the system with one cycle delay: at the instant t, we analyse the last cycle, which is already finished. In addition, our attention was focused on the part of a total cycle period, which includes the maximum of information, that is the aerobic period of the SBR cycle.

Given these predefined objectives, two different systems were developed depending on the available sensors:
- Case 1: a Decision Support System (DSS) for a configuration involving a low instrumentation process
- Case 2: a DSS for a configuration involving a process equipped with an advanced instrumentation

For the low instrumentation configuration, two subcases were investigated :
- Case 1.1: model-based approach
- Case 1.2: databased approach.
