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.

Reviews:“Anyone interested in the biology of wastewater treatment will find this book useful.”Biotechnology Advances “… is both well written and informative and it should appeal to anyone with an interest in wastewater treatment. It covers the ground in sufficient depth to stay useful throughout one's entire career, serving as an essential reference, allowing one to dive in and out at will as one's needs dictate … manages to fulfil what I believe to be its aim of bridging the gap between wastewater engineering and its underlying biology.”Journal of the Chartered Institution of Water and Environmental Management
Within the discipline of environmental sciences, the stable-isotope methodology is being increasingly used, especially in the study of the water cycle and of paleo-climatology. This book reviews the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionalism, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. It focuses on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, concludes up the presentation.

The provision of safe drinking water and the protection of public health and the environment through the treatment of wastewaters is increasingly informed by risk-based decision-making. Aspects of utility management such as process design and optimisation, asset management and compliance monitoring rely on a mature understanding of process risk within a broader context of business and environmental risk management. For operators, risk management is now regarded as a key business function. Understanding risk and being able to implement risk management is critical to the provision of safe drinking water. As part of a move towards a more strategic, forward looking approach to utility management, the IWA is promoting a risk-based approach to water utility management, from catchment to tap, through the implementation of the Bonn Charter (2004). *Why manage risk? *Basic probability and statistics *Process risk and reliability analysis *Assessing risks beyond the unit process boundary *Regulating water utility risks *Business risk management for water and wastewater utilities *Managing opportunity and reputational risk *Embedding better decision-making within utilities Having provided rationale for the importance of risk management, the text begins with the familiar territory of unit processes and process reliability. It then broadens out to consider, first environmental then organisational risk management. The final sections are concerned with better utility decision-making.

A practical guide to wastewater bacteria and the roles they performin wastewater treatment Communicating material in a practical manner for operators andtechnicians who regulate and troubleshoot their wastewatertreatment processes, Wastewater Bacteria discusses the effectivecontrol and proper operation of aerobic (activated sludge) andanaerobic (anaerobic digesters) biological treatment units toensure that an adequate, active, and appropriate population ofbacteria is present in each treatment unit. It is a hands-on guideto understanding the biology and biological conditions that occurat each treatment unit. Avoiding unnecessary technical jargon and chemical equations,Wastewater Bacteria, the fifth book in the Wastewater MicrobiologySeries, explores and explains: * Bacteria and the wastewater environment * Enzymes and sludge production * Nitrogen, phosphorus, and sulfur bacteria * Floc formation and filamentous organisms * Nitrification and denitrification * Sulfate reduction, fermentation, and methane production * Toxicity * Foam and malodor production The goal of Wastewater Bacteria is to enable plant operators toachieve the twofold basic objectives of wastewater treatment-todegrade organic wastes to a level where a significant, dissolvedoxygen demand is not exerted upon receiving waters and to removenutrients to levels where photosynthetic organisms in receivingwaters are limited in their growth. This straightforward manualequips plant technicians to meet these objectives with essentialinformation to understand the biological processes and organismsinvolved in wastewater treatment.
