Modelling is considered to be an inherent part of the design and operation of a wastewater treatment system. [...] Key Method In WEST’s graphical modelling environment, the physical layout of the plant can be rebuilt, and each building block can be linked to a specific model from the model base. The graphical information is then combined with the information in the model base to produce MSL-EXEC code, which can be compiled with a C++ compiler. In the experimentation environment, the user can design different…Expand
Modelling and simulation of a municipal WWTP with limited operational data
Mathematical modelling and simulation of activated sludge systems have gained increasing attention in wastewater treatment within the last years. In particular, standardized mathematical modelsExpand
Plant-wide modelling and simulation using steady-state data: a case study of the Gliwice WWTP, Poland
In last decade the focal point of the activated sludge (AS) modelling shifted from a secondary-treatment to a plant-wide level. This new approach offers more possibilities, therefore demands moreExpand
Development of a plant-wide steady-state wastewater treatment plant design and analysis program
Abstract Models are used as prognostic and diagnostic tools in order to design, analyse and optimise the biological and physical processes in a wastewater treatment plant (WWTP). This is done inExpand
Optimisation of a large WWTP thanks to mathematical modelling.
The main objective of this project is to develop a simplified mathematical tool able to reproduce and anticipate the behaviour of the Tougas WWTP (Nantes, France) and this tool is aimed to be used directly by the managers of the site. Expand
Mathematical Modelling in Diagnosis of Wastewater Treatment Plant
The paper reports the development of mathematical modelling in the diagnosis of the wastewater treatment plant (WWTP) and an innovative concept of the possible use the mathematical model and computer simulation in the diagnosed and control of activated sludge systems in WWTP is evaluated. Expand
Integrated urban catchment modelling for a sewer-treatment-river system
River water quality can be improved by optimising the urban wastewater system management through integrated operation of the transport and the treatment of these waters. Mathematical models are thenExpand
Transformers for interfacing anaerobic digestion models to pre- and post-treatment processes in a plant-wide modelling context
This work reviews, applies and compares two transforming/interfacing methods by connecting anaerobic digestion and activated sludge models, and validation of this general approach to interfacing any two models presented by Petersen matrices is presented. Expand
Modelling and optimisation of a chemical industry wastewater treatment plant subjected to varying production schedules
Industrial wastewater treatment plants (WWTPs) have to provide 100% reliability and availability for the discharging facilities at an industrial site. Varying production schedules at these facilitiesExpand
Full-scale modelling of food industry WWTP: Model evaluation and reuse
This study aimed at testing a mathematical model for an industrial WWTP. This model was developed in a previous study. The characterisation of the influent wastewater was repeated and resultsExpand
WST 50.7 L15 corr
Better controlling and optimising the plant’s processes has become a priority for WWTP (Wastewater Treatment Plant) managers. The main objective of this project is to develop a simplifiedExpand


Fast, simultaneous simulation of the integrated urban wastewater system using mechanistic surrogate models.
Mechanistic surrogate models are introduced here as simplified models that still contain some physical knowledge that can be implemented in the WEST simulator, which makes a simultaneous simulation of the system possible. Expand
The WEST++ wastewater treatment plant modelling and simulation environment
An overview of the WEST++ structure and functionality is given and the IAWQ1 model is the basis for a simple model of the dynamics of a basic WWTP. Expand
Evaluation of an ASM1 model calibration procedure on a municipal-industrial wastewater treatment plant
The purpose of the calibrated model determines how to approach a model calibration, e.g. which information is needed and to which level of detail the model should be calibrated. A systematic modelExpand
The interaction between activated sludge and a wastewater is subject to important cbanges. This is reflected not only in changing biokinetic parameters but also in changing model structures. The needExpand

This problem is addressed for the kinetic parameters of a simplified version of the recently published river water quality model no. 1 (RWQM1) and the selection of practically identifiable parameter subsets is discussed for typical boundary conditions as a function of the measurement layout. Expand
Biofilm models for the practitioner
Practitioners, experimenters and modelers should work together to identify the important processes that shoud be included in models and Guidance for model selection, calibration and application should be provided. Expand
Multi-formalism modelling and simulation
It is shown that there is a homomorphic relation between model and system: building a model of a real system and subsequently simulating its behaviour should yield the same results as performing a real experiment followed by observation and codifying the experimental results (see Figure 1.3).

Experimental design for the identification of macrokinetic models and model discrimination.
The macrokinetics of formate dehydrogenase (FDH) production with Candida boidinii were identified within 10 steady state experiments in a labscale continuous stirred tank reactor (10 model parameters) using an extended D-optimal design criterion. Expand
Activated sludge models ASM1, ASM2, ASM2d and ASM3
This book has been produced to give a total overview of the Activated Sludge Model (ASM) family at the start of 2000 and to give the reader easy access to the different models in their originalExpand
Activated sludge model No. 3
The Activated Sludge Model No. 3 (ASM3) can predict oxygen consumption, sludge production, nitrification and denitrification of activated sludge systems. It relates to the Activated Sludge Model No.Expand
