On 15 February, the International Water Association published the book 'Applications of Activated Sludge Models'. The book, edited by UNESCO-IHE, was prepared to celebrate the 25th anniversary of Activated Sludge Model Nr. 1 and includes fifteen practical applications of the activated sludge model for optimization, extension, upgrading, retrofitting and troubleshooting of wastewater treatment plants.
About the book
For 25 years, activated sludge models have played a crucial role in the development of the activated sludge process for wastewater treatment. These models are not typically academic; they do not aim to include every potential sub-processes involved in the activated sludge process. Instead, they are formulated with the minimum complexity needed to describe the relevant features of the process in practice. They also provide a systemized platform for the description of environmental biotechnological models in general, through the use of standardized notation and a matrix presentation.
Over the last two decades, wastewater research in Delft has benefitted greatly from the development of activated sludge models. On one hand, modelling has been expanded through the development of novel theoretical concepts and their application in new fields. On the other hand, models have been used for practical projects.
This book has been prepared to celebrate the 25th anniversary of Activated Sludge Model Nr. 1 (ASM1) and it includes fifteen practical applications of the activated sludge model for optimization, extension, upgrading, retrofitting and troubleshooting of wastewater treatment plants, carried out by the members of the Delft modelling group, master and doctoral students and partners. These applications present a good overview of the potential of modelling, and can be used as examples in courses.
The editors of the book are Professor Damir Brdjanovic, Associate Professor Carlos Lopez-Vazquez and Associate Professor Christine Hooijmans from UNESCO-IHE, Dr. Sebastiaan Meijer who owns the company Yuniko B.V. and Professor Mark van Loosdrecht, who is the group leader of Environmental Technology at TU Delft.
The editors trust the cases will inspire future engineers to use model as central tools in their work on improving the wastewater treatment technology through innovation and optimization.
The book can be ordered via the website of IWA publishing.
