Grids in control of anaerobic wastewater treatment plants: Leveraging the knowledge

A potential application of Grids systems is to anaerobic wastewater treatment plants (WWTP). This work extends previous simulation and data mining with a laboratory scale anaerobic digester, and shows that extending to an industrial scale plant gives valid and useful results for monitoring and control. The idea of a telecontrol centre for managing a group of plants is gaining acceptance. We investigate what barriers arise in applying data mining across multiple plants, in a Grids environment. One issue is heterogeneities, implying that data mining must be enhanced with the use of metadata. We examine the heterogeneities, link them to the model of Grids, and investigate their implications for metadata representation.
