Book Description
Special Offer: Cao Ye Shi Author Set - Buy all three books together and save a total £76! Many Biological Nitrogen Removal (BNR) activated sludge processes in warm climates are conservatively designed, because little systematic investigation has been carried out on the BNR activated sludge process in warm or tropical climates, although many studies under temperate climate conditions are available. This book covers a wide spectrum of mechanistic approaches to deal with BNR activated sludge related issues such as sewage and sludge characterization, dynamic performance of full-scale processes, laboratory simulation and modelling that leads to a mechanistic and more economic design. Recommendations on the operation, upgrading and design of BNR activated sludge process are formulated. This will significantly aid the promotion of nitrogen removal in wastewater treatment plants in warm or tropical climates, particularly in developing countries. The book has three purposes: to make recommendations for appropriate upgrading of existing activated sludge processes and assess the performance of the upgraded activated sludge processes; to explore the feasibility of employing laboratory-scale systems to simulate the performance of full-scale processes; and to use mathematical modelling calibrated with the measured data obtained from the laboratory-scale experimentation to study the performance and the design of full-scale processes. Reports are presented of comprehensive studies on: (i) on-site investigation of the activated sludge processes in three water reclamation plants (WRPs) in Singapore; (ii) laboratory-scale investigations to simulate the performance of full-scale activated sludge processes and to optimize the process design; and (iii) mathematical modelling and simulation with Activated Sludge Model No. 1 (ASM No. 1). Based on these detailed studies, guidelines on the operation, upgrading and design of the BNR activated sludge process in warm climates are presented. Results indicate that the laboratory-scale systems, designed based on the scale-down principles developed in this study and mathematic simulation with the model parameters calibrated by using the data obtained from the laboratory experiment, were able to describe the performance of the full-scale process.The applications of the approaches and principles are not limited to geographic locations and types of pollutants, and thus can reduce significantly the cost and time for the process development of the activated sludge process. This book will be an invaluable reference source for process and design engineers and consultants concerned with biological wastewater treatment as well as researchers in universities and research institutes.

Book Description
Since its conception almost a century ago, the activated sludge system has emerged as the dominant waste water treatment technology, with tens of thousands of implementations worldwide. The pivotal role played by the activated sludge system was originally due to its high efficiency in COD- and suspended solids removal, while more recently new processes for the removal of the macro-nutrients nitrogen and phosphorus have easily been accommodated.

Book Description
Mathematical Modelling and Computer Simulation of Activated Sludge Systems – Second Edition provides, from the process engineering perspective, a comprehensive and up-to-date overview regarding various aspects of the mechanistic (“white box”) modelling and simulation of advanced activated sludge systems performing biological nutrient removal. In the new edition of the book, a special focus is given to nitrogen removal and the latest developments in modelling the innovative nitrogen removal processes. Furthermore, a new section on micropollutant removal has been added. The focus of modelling has been shifting in the last years to models that can describe the performance of a whole plant (plant-wide modelling). The expanded part of this new edition introduces models describing the most important processes interrelated with the mainstream activated sludge systems as well as models describing the energy balance, operating costs and environmental impact. The complex process evaluation, including minimization of energy consumption and carbon footprint, is in line with the present and future wastewater treatment goals. By combining a general introduction and a textbook, this book serves both intermediate and more experienced model users, both researchers and practitioners, as a comprehensive guide to modelling and simulation studies. The book can be used as a supplemental material at graduate and post-graduate levels of wastewater engineering/modelling courses.
