This book will present the theory involved in wastewater treatment processes, define the important design parameters involved, and provide typical values of these parameters for ready reference; and also provide numerical applications and step-by-step calculation procedures in solved examples. These examples and solutions will help enhance the readers’ comprehension and deeper understanding of the basic concepts, and can be applied by plant designers to design various components of the treatment facilities. It will also examine the actual calculation steps in numerical examples, focusing on practical application of theory and principles into process and water treatment facility design.
This book introduces the 3R concept applied to wastewater treatment and resource recovery under a double perspective. Firstly, it deals with innovative technologies leading to: Reducing energy requirements, space and impacts; Reusing water and sludge of sufficient quality; and Recovering resources such as energy, nutrients, metals and chemicals, including biopolymers. Besides targeting effective C,N&P removal, other issues such as organic micropollutants, gases and odours emissions are considered. Most of the technologies analysed have been tested at pilot- or at full-scale. Tools and methods for their Economic, Environmental, Legal and Social impact assessment are described. The 3R concept is also applied to Innovative Processes design, considering different levels of innovation: Retrofitting, where novel units are included in more conventional processes; Re-Thinking, which implies a substantial flowsheet modification; and Re-Imagining, with completely new conceptions. Tools are presented for Modelling, Optimising and Selecting the most suitable plant layout for each particular scenario from a holistic technical, economic and environmental point of view.
Provides an excellent balance between theory and applications in the ever-evolving field of water and wastewater treatment Completely updated and expanded, this is the most current and comprehensive textbook available for the areas of water and wastewater treatment, covering the broad spectrum of technologies used in practice today—ranging from commonly used standards to the latest state of the art innovations. The book begins with the fundamentals—applied water chemistry and applied microbiology—and then goes on to cover physical, chemical, and biological unit processes. Both theory and design concepts are developed systematically, combined in a unified way, and are fully supported by comprehensive, illustrative examples. Theory and Practice of Water and Wastewater Treatment, 2nd Edition: Addresses physical/chemical treatment, as well as biological treatment, of water and wastewater Includes a discussion of new technologies, such as membrane processes for water and wastewater treatment, fixed-film biotreatment, and advanced oxidation Provides detailed coverage of the fundamentals: basic applied water chemistry and applied microbiology Fully updates chapters on analysis and constituents in water; microbiology; and disinfection Develops theory and design concepts methodically and combines them in a cohesive manner Includes a new chapter on life cycle analysis (LCA) Theory and Practice of Water and Wastewater Treatment, 2nd Edition is an important text for undergraduate and graduate level courses in water and/or wastewater treatment in Civil, Environmental, and Chemical Engineering.
Computer Modeling Applications for Environmental Engineers in its second edition incorporates changes and introduces new concepts using Visual Basic.NET, a programming language chosen for its ease of comprehensive usage. This book offers a complete understanding of the basic principles of environmental engineering and integrates new sections that address Noise Pollution and Abatement and municipal solid-waste problem solving, financing of waste facilities, and the engineering of treatment methods that address sanitary landfill, biochemical processes, and combustion and energy recovery. Its practical approach serves to aid in the teaching of environmental engineering unit operations and processes design and demonstrates effective problem-solving practices that facilitate self-teaching. A vital reference for students and professional sanitary and environmental engineers this work also serves as a stand-alone problem-solving text with well-defined, real-work examples and explanations.

Calling for ecologically and economically sound wastewater treatment systems, the authors of Natural Wastewater Treatment Systems explore the use of wetlands, sprinkler or deep irrigation, groundwater recharge, and other natural systems as sustainable methods for the treatment and management of wastewater. Based on work by prominent experts in natural waste treatment, this text provides a thorough explanation on how soil and plants can successfully sustain microbial populations in the treatment of wastewater. Determining that natural systems cost less to construct and operate, and require less energy than mechanical treatment alternatives, this book also explains how these processes produce lower amounts of residual solids, and use little or no chemicals. What’s New in the Second Edition: This revised edition includes current design and regulatory and operational developments in the natural wastewater treatment field. It provides detailed examples and analyses along with significant operational data in each chapter. It also considers how processes provide passive treatment with a minimum of mechanical elements, and describes new approaches to partially mixed ponds, including dual-powered aeration ponds. Introduces the planning procedures and treatment mechanisms responsible for treatment in ponds, wetlands, land application, and soil absorption systems Provides new case studies of constructed wetlands and water reuse systems Presents design criteria and methods of pond treatment and pond effluent upgrading Describes constructed wetlands design procedures, process applications, treatment performance data, and land treatment concepts and design equations Includes information on constituents of emerging concern (CEC) and their fate in natural systems The text discusses wastewater pond systems, free water surface constructed wetlands, subsurface and vertical flow constructed wetlands, land treatment, sludge management, and onsite wastewater systems. It describes residuals and biosolids management, including nitrogen removal pretreatment methods, and uses U.S. customary and metric units in all chapters. It presents case studies of new applications of natural systems and includes worked examples of design equations for ponds and land treatment. It also provides a biosolids regulatory update from a top EPA scientist, and algae reduction technologies for ponds and wetlands. Designed for practicing wastewater engineers and scientists involved in the planning, design, and operation of ponds, wetlands, land treatment, biosolids, and onsite soil-based treatment systems, the book integrates many natural treatment systems into one single source.
Putting forward an innovative approach to solving current technological problems faced by human society, this book encompasses a holistic way of perceiving the potential of natural systems. Nature has developed several materials and processes which both maintain an optimal performance and are also totally biodegradable, properties which can be used in civil engineering. Delivering the latest research findings to building industry professionals and other practitioners, as well as containing information useful to the public, ‘Biotechnologies and Biomimetics for Civil Engineering’ serves as an important tool to tackle the challenges of a more sustainable construction industry and the future of buildings.
