ISCWAP - A KNOWLEDGE-BASED SYSTEM FOR SUPERVISING ACTIVATED-SLUDGE PROCESSES

A Knowledge-Based System for the on-line supervision of activated slud ge processes in wastewater treatment is presented. The system performs on-line data acquisition from the sensors installed in the plant, off line data management of results from analytical determinations in the plant laboratory, and qualitative information supplied by the supervis ors of the process. All these elements are integrated in the Intellige nt System for Supervision and Control of WAste water treatment Plants (ISCWAP), which includes a set of diagnosis, detection, prediction and operation rules, making the system capable to handle with several usu al situations (where mathematical control can be useful) and also with some unusual situations (where quantitative and qualitative informati on must be considered).
