Development of an integrated approach for wastewater treatment plant
optimization based on dynamic modelling and environmental assessment
Résumé
Wastewater treatment plants are moving towards energy and nutrients recovery
facilities. Simultaneously, they are submitted to stricter regulation with respect to
environment and human health. Facing the great challenge of reducing operational
costs along with the reduction of environmental impacts and the guaranty of plants
robustness, tools might be developed in order to provide an integrated assessment.
The goal of this work is to develop a reliable and predictive framework containing
rigorous dynamic wide-plant modelling, extended boundaries life cycle assessment for
scenarios evaluation and an efficient multi-objective optimization tool. The developed
framework for environmental evaluation coupled to dynamic modelling was initially
applied to several case studies including urine source separation, enhanced primary
clarification and urine treatment by nitritation/ anaerobic ammonium oxidation, offering
both performance results and environmental hotspots. Given the important benefits of
the urine source separation provided by the previous results, a flexible and dynamic
phenomenological influent generator was adapted in order to provide realistic dynamic
data concerning urine and wastewater streams in different urine retention scenarios.
Finally, as the complex combination of biological, chemical and physical processes
leads to a computational expensive problem, a feasibility study (computational time
and reliability) on the multi-objective optimization was conducted. Obtaining a set of
solutions that avoids any prior discrimination among costs, environment and
performance allowed thus the discussion of the involved trade-offs. Finally, the
complete framework was applied to several case studies lightening on operational
aspects of more sustainable options on wastewater management and treatment.
