This book was released on 2007-11-10 with total page 697 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past thirty years have witnessed a growing worldwide desire that po- tive actions be taken to restore and protect the environment from the degr- ing effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been id- tified: (1) How serious is the pollution? (2) Is the technology to abate it ava- able? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers f- mulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.

Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide to take positive actions to restore and protect the environment from the degrading effects of all forms of pollution: air, noise, solid waste, and water. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identified: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? The principal intention of the Handbook of Environmental Engineering series is to help readers formulate answers to the last two questions. The traditional approach of applying tried-and-true solutions to specific pollution pr- lems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a “methodology of pollution c- trol. ” However, realization of the ever-increasing complexity and interrelated nature of current environmental problems makes it imperative that intelligent planning of pollution abatement systems be undertaken.

Download or read book Physico Chemical Aspects of Food Processing written by S.T. Beckett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food processing is now the biggest industry in the UK and in many other countries. It is also rapidly changing from what was essentially a craft industry, batch processing relatively small amounts of product, to a very highly automated one with continuously operating high speed production lines. In addition, consumers have developed a greater expectation for consistently high standard products and coupled this with demands for such things as a more natural flavour, lower fat etc. The need for an increased knowledge of the scientific principles behind food processing has never been greater. Within the industry itself, increased automation, company diversification and amalgamations etc. have meant that those working in it have often to change their field of operation. Whereas twenty years ago, someone starting work in one branch of the food industry could expect, if he or she so desired, to work there all their working lives, this is now seldom the case. This means that a basic knowledge of the principles behind food processing is necessary both for the student at university or college, and for those already in the industry. It is hoped, therefore, that this book will appeal to both, and prove to be a useful reference over a wide range of food processing.

Download or read book Food and Agricultural Wastewater Utilization and Treatment written by Sean X. Liu and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food and Agricultural Wastewater Utilization and Treatment focuses on the cost-effective treatment technologies specific for food and agriculture wastewater and possible economical recovery of valuable substances from wastewater during common food processing and postharvest operations using innovative technologies. The technologies included in the book are not a mere collection of all known relevant technologies. Instead, priority consideration is given to those technologies that can not only solve the environmental problem of wastewater disposal but also reduce the wastewater management cost in the long run for food and agriculture industries. The book combines past decades of research on food and agricultural wastewater issues with an abundance of emerging research on innovative separation technologies to separate biological molecules from complex biological systems. Food technologists as well as environmental and agricultural engineers/scientists will find Food and Agricultural Wastewater Utilization and Treatment invaluable in their quest of improving food and agricultural wastewater management.

Download or read book Physicochemical Methods of Mineral Analysis written by A. Nicol and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has developed from a short residential course organised by the Department of Minerals Engineering and the Department of Extra Mural Studies of the University of Birmingham. The course was concerned mainly with physical methods of analysis of minerals and mineral products, and particular regard was given to 'non-destructive' methods, with special emphasis on newly available techniques but with a review of older methods and their recent developments included therein. Mineral analysis is obviously of great importance in all the stages of mineral exploration, processing, and utilisation. Selection of a method for a particular mineral or mineral product will depend upon a number of factors, primarily whether an elementary analysis or a phase or structure analysis is required. It will also depend upon the accuracy required. The chapters in the book covering the different methods show the range of useful applicability of the methods considered and should prove valuable as an aid or methods for a given set of circumstances. in selecting a suitable method The book, referring as it does to the majority of the instrumental methods available today (as well as, for comparison, a useful contribution on the place of classical wet chemical analysis) will be valuable to the student as well as to those analysts, research workers, and process engineers who are concerned with the winning, processing, and utilisation of minerals and mineral products.

Download or read book Manganese Removal from Groundwater written by J.H. Bruins and published by CRC Press. This book was released on 2017-03-16 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Netherlands, Belgium and other European countries, manganese is removed by conventional groundwater treatment with aeration and rapid (sand) filtration. Such a treatment process is easy to operate, cost effective and sustainable, because it does not make use of strong oxidants such as O3, Cl2, ClO2 and KMnO4 with the associated risk of by-product formation and over or under dosing. However, application of aeration-filtration is also facing drawbacks, especially the long ripening time of filter media. Due to the long ripening time, water companies have to waste large volumes of treated water, making this process less sustainable. Also, costs associated with filter media ripening (man power, electricity, operational and analysis costs) are high. Therefore decreasing the filter ripening time, regarding manganese removal is a big issue. Although already extended research has been carried out into manganese removal, the controlling mechanisms, especially of the start up face of filter media ripening, are not fully understood yet. The emphasis of this thesis is to provide a better understanding of the mechanisms involved in the ripening of virgin filter media, regarding manganese removal and how to shorten or completely eliminate the long ripening period of filters with virgin material. This thesis therefore highlights the role of the formation of a manganese oxide coating on virgin filter media. Characterization and identification revealed that the responsible manganese oxide for an effective manganese removal was Birnessite. It was found that Birnessite, formed at the beginning of the ripening process was of a biological origin. Based on the knowledge that manganese removal in conventional groundwater treatment is initiated biologically, long ripening times may be reduced by creating conditions favouring the growth of manganese oxidizing bacteria, e.g., by limiting the back wash frequency and / or intensity. Additionally, this thesis also shows that the use of freshly prepared manganese oxide, containing Birnessite, can completely eliminate filter media ripening time.
