Environmental Decision Support Systems a useful tool to cope with wastewater management complexity

Poch, M. – LEQUIA. Institute of the Environment. University of Girona (UdG)


Wastewater Treatment Plants (WWTP) operation implies complex relationships between biological, physical and chemical processes, doing their management a complex task. Moreover, the occurrence of new objectives in the context of more strict sustainability paradigm would even increase the management complexity of these systems, as new parameters are foreseen to be taken into account in next years. Simultaneously, in the
last years an impressive effort has been made to incorporate new monitoring devices able to provide more information and this will increase in the near future.
To manage all these elements in an efficient way, new advanced computer tools will be required, hybrid tools that should be able to integrate on-line data, off-line data, statistical techniques, mathematical models and heuristic knowledge.
In this paper we propose the use of Environmental Decision Support Systems like one of these tools, presenting our experience in the development and application of EDSS to WWTP, from the basic research to the implementations in real plants treating more than one million of cubic meters a day.
