This paper presents the theoretical basis and the main results obtained during the development and full-scale experimental validation of the new supervisory control strategy designed for the Galindo-Bilbao wastewater treatment plant (WWTP). The different phases of the project have been carried out over the last 8 years, combining model simulations,(More)
This paper presents a new model for the dynamic prediction of water quality in rivers using in-series continuously stirred tank reactors (CSTR) and process transformations based on the IWA RWQM1. The transport model introduces a new parameter f (fraction of solids that are not retained in the in-series reactors) that splits hydraulic and solids retention(More)
A new concept of Multi-Residential Gateway (MRG) capable of managing several residential units (e.g. homes, flats) simultaneously while offering new additional services is presented. Apart from the typical recommendations proposed for residential gateways, specific new requirements are introduced in order to overcome the multi-residential challenge. A novel(More)
This paper presents a mathematical formulation for the optimum design of a new activated sludge WWTP. The WWTP optimum design problem has been formulated as a Mathematical Programming problem, which is solved through a nonlinear optimisation method. The plant model has been based on the ASM1. The minimum volume of the biological reactors and the minimum(More)
This paper proposes the use of predictive optimal control as a suitable methodology to manage efficiently transport water networks. The predictive optimal controller is implemented using MPC control techniques. The Arrêt-Darré/Arros dam-river system located in the Southwest region of France is proposed as case study. A high-fidelity dynamic simulator based(More)
The Residential Gateway (RG) is known as the connection box that provides multi-service access to the consumer networks. This work is focused on a MultiResidential Gateway (MRG) concept, which offers more service provisioning and management capabilities. The QoS support in this context is challenging, as new requirements must be fulfilled regarding such(More)
This paper presents a new sensitivity analysis methodology for Activated Sludge WWTPs. It is based on both (a) the calculation of the range of "manipulated input variables" that satisfy the restrictions imposed on the "output variables" and (b) on the computation of isolines of the output variables inside the feasible operating space. This analysis allows a(More)
Traditionally, Internet has provided best-effort service to every user regardless of its requirements. However, as Internet becomes universally available, users demand more bandwidth and applications require more and more resources, and interest has developed in having the Internet provide some degree of Quality of Service. Although QoS is an important(More)
Quality of service management support is a key factor in developing new products. This paper presents and implements an architecture for sharing Internet access among several users supporting QoS management based on differentiated services philosophy. For implementation details, existing Linux traffic control capabilities are mentioned in the paper, but a(More)
