This book was released on 2013-04-17 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the dawn of the 21st century, biotechnology is emerging as a key enabling technology for sustainable environmental protection and stewardship. Biotechnology for the Environment: Wastewater Treatment and Modeling, Waste Gas Handling illustrates the current technological applications of microorganisms in wastewater treatment and in the control of waste gas emissions. In the first section of the book special emphasis is placed on the use of rigorous mathematical and conceptual models for an in-depth understanding of the complex biology and engineering aspects underlying the operation of modern wastewater treatment installations. The second part addresses waste gas biofiltration, an expanding biotechnological application of microbial metabolism for air quality assurance through processes ranging from the abatement of hazardous volatile pollutants to the elimination of nuisance odors. It will be a valuable reference source for environmental scientists, engineers and decision makers involved in the development, evaluation or implementation of biological treatment systems.

Download or read book Hazardous Pollutants in Biological Treatment Systems written by Ferhan Çeçen and published by IWA Publishing. This book was released on 2017-11-15 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hazardous pollutants are a growing concern in treatment engineering. In the past, biological treatment was mainly used for the removal of bulk organic matter and the nutrients nitrogen and phosphorous. However, relatively recently the issue of hazardous pollutants, which are present at very low concentrations in wastewaters and waters but are very harmful to both ecosystems and humans, is becoming increasingly important. Today, treatment of hazardous pollutants in the water environment becomes a challenge as the water quality standards become stricter. Hazardous Pollutants in Biological Treatment Systems focuses entirely on hazardous pollutants in biological treatment and gives an elaborate insight into their fate and effects during biological treatment of wastewater and water. Currently, in commercial and industrial products and processes, thousands of chemicals are used that reach water. Many of those chemicals are carcinogens, mutagens, endocrine disruptors and toxicants. Therefore, water containing hazardous pollutants should be treated before discharged to the environment or consumed by humans. This book first addresses the characteristics, occurrence and origin of hazardous organic and inorganic pollutants. Then, it concentrates on the fate and effects of these pollutants in biological wastewater and drinking water treatment units. It also provides details about analysis of hazardous pollutants, experimental methodologies, computational tools used to assist experiments, evaluation of experimental data and examination of microbial ecology by molecular microbiology and genetic tools. Hazardous Pollutants in Biological Treatment Systems is an essential resource to the researcher or the practitioner who is already involved with hazardous pollutants and biological processes or intending to do so. The text will also be useful for professionals working in the field of water and wastewater treatment.

Download or read book The Microbiology of Activated Sludge written by Robert J. Seviour and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has been a long time in preparation. Initially it grew out of our frustrating attempts over the past ten years to identify the filamentous bacteria seen in large numbers in most activated sludge plants, and the realization that we know very little about them and the other microbial populations in these systems. Unfortunately this book does not provide many answers to the problems these filamentous bacteria can cause, but we hope it might encourage microbiologists and engineers to communi cate more with each other and to spend some time trying to understand the tax onomy, ecology and physiology of activated sludge microbes. It is now very timely, for example, to try to provide these filamentous bacteria with proper taxonomically valid names and to determine their correct place in bacterial classifications. This book is not meant to compete directly with the books by Gray (1989, 1990) nor the excellent manual published by Jenkins and coworkers (1993b), which has been invaluable to us and others trying to identify filamentous bacteria. Wanner's book (1994a) also provides an excellent account of the problems of bulking and foaming caused by filamentous bacteria. These publications and others by Eikelboom's group have made an enormous contribution to the study of filamentous bacteria, and will con tinue to do so.

Available in PDF, EPUB and Kindle. Book excerpt: The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste production, 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 identi ed: (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? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci c pollution problems 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 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.

Download or read book Industrial Wastewater Treatment by Activated Sludge written by Derin Orhon and published by IWA Publishing. This book was released on 2009-02-02 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Industrial pollution is still a major concern and despite its significance, sound and systematic pollution control efforts are very poorly documented. The character and treatability of industrial wastewaters is highly variable and specific for each industrial activity. Biological treatment with activated sludge is the appropriate technology for industrial wastewaters from several major industrial sectors. Industrial Wastewater Treatment by Activated Sludge deals with the activated sludge treatment of industrial wastewaters by considering conceptual frameworks, methodologies and case studies, in a stepwise manner. The issues related to activated sludge treatment, such as biodegradability based characterization, modeling, assessment of stoichiometric and kinetic parameters and design, as well as the issues of industrial pollution control, e.g. in-plant control, effect of pretreatment, etc. are combined in a way to provide a comprehensive and information-rich view to the reader. By doing so, the book supplies an up-to-date reference for industrial wastewater experts and both graduate and undergraduate students. Industrial Wastewater Treatment by Activated Sludge provides a roadmap, describing the methodologies for the treatment of industrial wastewaters from several major sectors, based on a solid theoretical background. Up to now although valuable separate efforts both on activated sludge and industrial wastewater treatment have been presented, an integrated approach that is crucial to practice has not been available. This gap is filled by this book.
