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.

Biological Treatment of Industrial Wastewater presents a comprehensive overview of the latest advances and trends in the use of bioreactors for treating industrial wastewater.

Technical information for using activated sludge to treat effluents from multiple industries Covers virtually all traditional and advanced methods, as well as treatability and process modeling New methods for removing U.S. and European regulated microconstituents, trace organics, active pharmaceutical ingredients and other contaminants Explains advances in water reuse and plant retrofitting Useful for in-house training This comprehensive book presents critical information on the applications of activated sludge for treating industrial wastewaters, as well as other effluents that impact POTWs. The book offers details on how advances in activated sludge can be deployed to meet more stringent discharge limits by explaining many novel variations of activated sludge and offering technical guidance on process modeling and optimization. Special attention is given to emerging contaminants and water reuse strategies. Case studies are drawn from the pharma, food and shale gas industries. Based on short courses taught by the authors, as well as hundreds of hours of in-plant consulting, this book offers the tools to understand and modify the activated sludge process for superior and sustainable wastewater treatment. From the Authors' Preface: "After speaking with practitioners, operators and engineers, the authors felt a new text was needed...to cover the following developments: "the continued evolution of the activated sludge process and its numerous designs, configurations and technology developments; "design of industrial water reuse systems...to achieve industry sustainability goals; "changes...from BOD, TSS and nutrient removal to removal of specific organics, toxicity...microconstituents, and more stringent effluent permit limits; "advances in process modeling tools that can be used in combination with treatability testing tools for plant design, optimization and troubleshooting; "concerns over industrial wastewater discharge impacts to POTWs, such as nitrification inhibition, the impact of frac water...and the fate of microconstituents through POTWs."

Water pollution occurs when toxic pollutants of varying kinds (organic, inorganic, radioactive and so on) are directly or indirectly discharged into water bodies without adequate treatment to remove such potential pollutants. Today's sources of these potential pollutants, which cause high deterioration of freshwater quality, are city sewage and industrial waste discharge, human agricultural practices, industrial waste disposal practices, mining activities, civil and structural work activities and obviously natural contamination with climate change. When our water is polluted, it is not only devastating to the environment but also to human health. Therefore, development of water and wastewater treatment processes to alleviate water pollution has been a challenging and demanding task for engineers, scientists and researchers. Perhaps this is even more challenging for underdeveloped and developing countries, where water and wastewater treatment facilities, knowledge and infrastructure are limited. Water and wastewater treatment processes are broad and often multidisciplinary in nature, comprising a mixture of research areas including physical, chemical and biological methods to remove or transform various potential pollutants. This is in hopes to achieve acceptable water quality and satisfy governmental and environmental protection agencies' laws and regulations. With these objectives, this book has been written in order to provide various research results and compilation and up-to-date development on the current states of knowledge and techniques in the broad field of water and wastewater treatment processes. Basically, this book will give a comprehensive understanding and advancement and application of various physical, chemical and biological treatment methods in the reduction of potential pollutants (inorganics/organics) from water and wastewater. There are a total 18 book chapters contributed by large number of expert authors around the world, covering the following main research areas: Physical, chemical and biological water treatment processes such as adsorption, biosorption, coagulation/flocculation, electrocoagulation, denitration, membrane filtration/separation, photo-catalytic reduction, advanced oxidation, nutrients removal by struvite crystallisation and nanotechnology; Physical, chemical and biological methods for municipal wastewater and industrial wastewater treatment plants such as primary-secondary sludge treatments, anaerobic digestions, aerobic treatment, activated sludge processes, dewaterability by flocculants, pre-treatments of sludge and rheology of sludge in wastewater treatment; Various operational units/equipment and process control of wastewater treatment plant.

Advances in Industrial Wastewater Treatment Technologies: Removal of Contaminants and Recovery of Resources identifies emerging technologies that allow for reuse throughout the wastewater treatment cycle. In anticipation of the next generation of biological treatment technologies driven wastewater treatment plants, this book focuses on the reuse and regeneration of wastewater through an innovative and applied approach of treatment processes. The book emphasizes various aspects related to wastewater management, treatment technologies, water reuse, biosolids production and management, water quality, regulations, economics, public acceptance, risk assessment, benefits, keys for success and main constraints, and stresses the importance of an activated sludge process. Demonstrates state-of-the-art wastewater treatment technologies Highlights the importance of treatment technologies for better reuse of wastewater Discusses removal of various emerging contaminants through different processes to clean up the environment from pollution Provides an updated vision of existing treatment process strategies with their limitations and challenges and their potential applications for the removal of pollutants in the environment and from industrial effluent

This book focuses on industrial wastes that either join the streams or other natural water bodies directly, or are emptied into the municipal sewers, and their characteristics vary widely depending on the source of production and the raw material used by the industry, even during pre-industrial, industrial period and prospect of wastewater treatment for water resource conservation. The treatment of industrial wastewater can be done in part or as a whole either by the biological or chemical processes. Advanced treatment methods like membrane separation, ultra-filtration techniques and adsorption are elaborated. It would emphasize and facilitate a greater understanding of all existing available research, i.e., theoretical, methodological, well-established and validated empirical work, associated with the environment and climate change aspects.
