An Introduction to Water Quality Modelling Second Edition Edited by A. James Department of Civil Engineering, University of Newcastle upon Tyne, UK This book presents a simple introduction (for those not familiar with modelling, computing or numerical methods) to the use of modelling techniques and their applications in the management of water quality. Eight years have passed since the first edition of the book was published and there has been a tremendous increase in the use of mathematical models in environmental engineering, especially the control of pollution in rivers and estuaries. Modelling has also addressed a much wider range of pollutants and there has been an increase in the range of conceptual approaches to the formulation of models. The text of this second edition has therefore been modified to reflect these changes. The chapters dealing with techniques have been expanded to cover a greater range of kinetics and introduce a background of understanding for statistical techniques and time series analysis. Similarly, the chapters dealing with the application of models to rivers, estuaries, lakes, groundwater and the marine environment have been expanded and updated. The overall aims of the book, however, remain the same, making it an ideal introductory text for people wishing to learn about water quality modelling.

Esta 9ª edición constituye una obra de síntesis que presenta las técnicas modernas de análisis químicos, biológicos y microbiológicos del agua. Con los avances tecnológicos más recientes en el campo de la química analítica, esta nueva edición presenta un contenido fundamentalmente renovado, pero conservando el espíritu y la forma de ediciones anteriores. Enriquecida con datos referentes a los numerosos contaminantes orgánicos determinados por las nuevas reglamentaciones, integra los contaminantes emergentes y se basa en los nuevos indicadores biológicos que permiten la evaluación del estado ecológico de las masas de agua

This comprehensive text provides the reader with both a detailed reference and a unified course on wastewater treatment. Aimed at scientists and engineers, it deals with the environmental and biological aspects of wastewater treatment and sludge disposal. The book starts by examining the nature of wastewaters and how they are oxidized in the natural environment. An introductory chapter deals with wastewater treatment systems and examines how natural principles have been harnessed by man to treat his own waste in specialist reactors. The role of organisms is considered by looking at kinetics, metabolism and the different types of micro-organisms involved. All the major biological process groups are examined in detail, in highly referenced chapters; they include fixed film reactors, activated sludge, stabilization ponds, anaerobic systems and vegetative processes. Sludge treatment and disposal is examined with particular reference to the environmental problems associated with the various disposal routes. A comprehensive chapter on public health looks at the important waterborne organisms associated with disease, as well as removal processes within treatment systems. Biotechnology has had an enormous impact on wastewater treatment at every level, and this is explored in terms of resource reuse, biological conversion processes and environmental protection. Finally, there is a short concluding chapter that looks at the sustainability of waste water treatment. The text is fully illustrated and supported by over 3000 references
