Available in PDF, EPUB and Kindle. Book excerpt: This title includes a number of Open Access chapters. The activated sludge process is one of the most versatile and commonly used wastewater treatment systems in the world. In the past, when industrial wastewater treatment focused on removing biological oxygen demand and suspended solids, waste water plants needed different processes and technology. The shift to the activated sludge process means environmental engineers must build new treatment plants and retrofit old ones. In this compendium, the editor, an experienced and well-published scientist in the field, has brought together articles that relate to the new requirements.

Download or read book Advanced Biological Treatment Processes written by Lawrence K. Wang and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 738 pages. 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. 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 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 en- neering, 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.

Available in PDF, EPUB and Kindle. Book excerpt: The past few years have seen the emergence of a growing, widespread desire in this country, and indeed everywhere, that positive actions be taken to restore the quality of our environment, and to protect it from the degrading effects of all forms of pollution-air, noise, solid waste, and water. Since pollution is a direct or indirect consequence of waste, if there is no waste, there can be no pollution, and the seemingly idealistic demand for "zero discharge" can be construed as a demand for zero waste. However, as long as there is waste, we can only attempt to abate the consequent pollution by converting it to a less noxious form. In those instances in which a particular type of pollution has been recognized, three major questions usually arise: (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 this series of books on environmental engineering is to help the reader formu late useful answers to the second and third of these questions, i. e. , to outline the best currently available engineering solutions, and to examine their costs in the light of the real level of benefits afforded. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major factor contributing to the success of environmental engineering, and in large measure has ac counted for the establishment of a "methodology of pollution control.

Download or read book Activated Sludge Wastewater Treatment written by Eric Wahlberg and published by . This book was released on 1918-12-17 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a milestone in the evolution of wastewater treatment operations. It explains the science of treatment framed within an ethics where wastewater personnel are seen as protectors of public health, preservers of the environment, and stewards of public monies. Written by a former plant operator with a Ph.D., the book presents the fundamental science behind the unit processes in wastewater treatment plants, including biological nutrient removal. In so doing, it challenges longstanding operational doctrines enshrined by habit and tradition, such as being careful not to remove too many influent organics in a primary clarifier for fear of starving the microorganisms in the aeration basin, or using the MLSS concentration to control effluent quality, or cutting the growth rate of microorganisms in anticipation of their slower growth rate in winter. Dispelling much of the prevailing that's-the-way-we've-always-done-it dogma is achieved through an elegant and understandable presentation of the biology, chemistry, and physics that explain the phenomena of wastewater treatment. At the same time, the book is intensely practical. It offers detailed and data-based process control solutions to stabilize plant performance, maintain consistent effluent quality, and reduce energy costs. Powerful, easily implemented statistical techniques are given to unlock the meaning of plant performance data and make informed process control decisions. The book's approach is learning-focused, including numerous examples of a failsafe, foolproof arithmetical method that enables operations professionals to define, set up, and solve problems.
Download or read book A B processes Towards Energy Self sufficient Municipal Wastewater Treatment written by Yu Liu and published by IWA Publishing. This book was released on 2019-11-15 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principle of the conventional activated sludge (CAS) for municipal wastewater treatment is primarily based on biological oxidation by which organic matters are converted to biomass and carbon dioxide. After more than 100 years’ successful application, the CAS process is receiving increasing critiques on its high energy consumption and excessive sludge generation. Currently, almost all municipal wastewater treatment plants with the CAS as a core process are being operated in an energy-negative fashion. To tackle such challenging situations, there is a need to re-examine the present wastewater treatment philosophy by developing and adopting novel process configurations and emerging technologies. The solutions going forward should rely on the ways to improve direct energy recovery from wastewater, while minimizing in-plant energy consumption. This book begins with a critical overview of the energy situation and challenges in current municipal wastewater treatment plants, showing the necessity of the paradigm shift from removal to recovery in terms of energy and resource. As such, the concept of A-B process is discussed in detail in the book. It appears that various A-B process configurations are able to provide possible engineering solutions in which A-stage is primarily designed for COD capture with the aim for direct anaerobic treatment without producing excessive biosludge, while B-stage is designated for nitrogen removal. Making the wastewater treatment energy self-sustainable is obviously of global significance and eventually may become a game changer for the global market of the municipal wastewater reclamation technology. The principal audiences include practitioners, professionals, university researchers, undergraduate and postgraduate students who are interested and specialized in municipal wastewater treatment and process design, environmental engineering, and environmental biotechnology.

Download or read book Unit Operations in Environmental Engineering written by Robert Noyes and published by William Andrew. This book was released on 1994-12-31 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the practical aspects of environmental technology organized into eight chapters relating to unit operations as follows: 1. Biological Technology 2. Chemical Technology 3. Containment and Barrier Technology 4. Immobilization Technology 5. Membrane Technology 6. Physical Technology 7. Radiation and Electrical Technology 8. Thermal Destruction Technology Traditional technologies have been included, as well as those that can be considered innovative and emerging. The traditional approaches have been the most successful, as contractors are careful about bidding on some of the newer technologies. However, as regulatory requirements increase, markets will open for the innovative and emerging processes. There will be increasing pressure to break down complex waste streams, with each subsequent stream demanding separate treatment. In addition, a number of technologies have been developed by combining processes directly, or in a treatment train, and these developments are expected to assume increasing importance. However, such concerns as uncertainties due to liability, regulatory approval, price competition, and client approval have limited the application of some of these newer technologies.
