Book Description
Our rivers and lakes are continuously self-purifying thanks to algal and bacterial biofilms that grow over the surface of stones and other debris. This same process has been employed for over a century to treat our municipal and industrial wastewater in specially designed fixed film reactors that maximize this microbial activity by providing ideal growth conditions and unlimited food and oxygen. Fixed film, or attached biofilm, reactors are unique in their ability to treat complex wastewaters and shock loadings; using far less energy than other wastewater treatment processes such as activated sludge, making them a sustainable treatment option.Targeted at undergraduate and postgraduate engineers and scientists, this book follows the structure of bestseller Biology of Wastewater Treatment. This volume gives an expanded and up-to-date overview of the use of fixed-film reactors in wastewater treatment with content spanning from biofilm formation, to traditional trickling filters and rotating biological contactor technology, advanced submerged systems (including MBBRs and IFAS) and their key role in the treatment of contaminated air, and finally to nitrogen removal employing new microbial pathways such as Anammox. This monograph emphasizes the biological aspects of the processes.

Fixed film, or attached biofilm, reactors are unique in their ability to treat complex wastewaters and shock loadings; using far less energy than other wastewater treatment processes such as activated sludge, making them a sustainable treatment option.This new book, based on a chapter from the bestseller Biology of Wastewater Treatment, gives an expanded and up-to-date overview of the use of fixed film reactors in wastewater treatment. This volume's content spans from biofilm formation, through traditional trickling filters and rotating biological contactor technology, advanced submerged systems including MBBRs and IFAS, their key role in the treatment of contaminated air, and finally to nitrogen removal employing new microbial pathways such as Anammox. The monograph emphasizes the biological aspects of the processes that will also be of interest to engineers.The book is aimed equally at engineers and scientists at both the undergraduate and postgraduate level, who will find it accessible and easy to understand. It will also be a useful reference for practitioners.

Book Description
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. Contents:How Nature Deals with WasteHow Man Deals with WasteThe Role of OrganismsFixed-Film ReactorsActivated SludgeNatural Treatment SystemsAnaerobic Unit ProcessesSludge Treatment and DisposalPublic HealthBiotechnology and Wastewater Treatment Readership: Graduate students in wastewater technology. 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

Book Description
A balance between process efficiency and structural integrity is the prime objective in designing a large scale fixed film reactor for wastewater treatment. Various criteria must be considered before the proper biological oxidation media can be selected to achieve an optimum design. This paper examines the criteria for selecting plastic media, its performance standards, and its properties, such as its modulus of elasticity at the maximum working temperatures it will withstand; the ability of the media to retain these properties when exposed to the deleterious effects of chemicals, physical impact, and ultraviolet light; and the media's ability to remain efficient as biota growth accumulates on its surfaces. Performance standards for determining the maximum load plastic biofilter modules can support are also discussed. These standards were developed to provide a media which has structural strength to remain functional for the life of the process.
