Coagulation and Flocculation in Water and Wastewater Treatment provides a comprehensive account of coagulation and flocculation techniques and technologies in a single volume covering theoretical principles to practical applications. Thoroughly revised and updated since the 1st Edition it has been progressively modified and increased in scope to cater for the requirements of practitioners involved with water and wastewater treatment. A thorough gamut of treatment scenarios is attempted, including turbidity, color and organics removal, including the technical aspects of enhanced coagulation. The effects of temperature and ionic content are described as well as the removal of specific substances such as arsenic and phosphorus. Chemical phosphorus removal is dealt with in detail, Rapid mixing for efficient coagulant utilization, and flocculation are dealt with in specific chapters. Water treatment plant waste sludge disposal is dealt with in considerable detail, in an Appendix devoted to this subject. Invaluble for water scientists, engineers and students of this field, Coagulation and Flocculation in Water and Wastewater Treatment is a convenient reference handbook in the form of numerous examples and appended information.

Laboratory investigations into the use of magnesium carbonate instead of alum for coagulation have demonstrated that the magnesium carbonate system produces a treated water with superior characteristics compared to water treated with alum. Both turbidity and organic color removals were comparable for both processes, and the flocs formed by the magnesium carbonate process were larger and heavier than alum flocs with better settling characteristics. The process involves the use of the magnesium carbonate as a coagulant and lime is added to precipitate gelatinous Mg(OH)2. The sludge, composed of a slurry of Mg(OH)2, CaCO3, and clay is carbonated and the Mg(OH)2 selectively and completely dissolved. Recycle after filtering allows re-use of both the magnesium carbonate and the sludge water. CaCO3 can also be recovered easily in large plants or landfilled at small ones. Chemical treatment costs for most waters can be substantially reduced using this system, while the quality of treated water will be superior to the quality of alum-treated water.

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.

With joy and pride parents observe the coming of age of their children, confer. , ence conveners the acceptance of their programmes, and editors the demand for their volumes. The scientific advisory board of the Gothenburg . . Symposia, the Springer publishing house of the proceedings and the editors are more than pleased with the fact that the demand for these books far exceeds the supply. The themes vocalized by the Gothenburg Symposia reHect research and development needs for the environment more than envisioned at the concep tion of the conferences. An environment-oriented analysis of the situation, not confined to the European community, furnishes the following results: (1) Due to the very high population density in many areas environmental quality is endangered; this has become apparent at the very moment in particular in the aqueous habitat and is corroborated by corresponding regulation proposals from the European Council. (2) Pollution control concepts and measures are developed to a varying degree in many countries of the world, reHecting in most instances the need for environmental protection and the closely related devel opment of (judicial and technical) measures. In most instances these controlling and protective measures need to be intensified. (3) Thus, nearly all countries face the problem of developing and/or improving pollution control strategies, i. e. building new treatment plants, upgrading overloaded or outdated instal lations and designing new operating and controlling strategies for improved plant performance.

This manual is a source document for utilities that are considering a coagulant changeover. It is intended to provide an appreciation of what must be considered for a successful changeover based on the input of U.S. and Canadian utilities (Chapters 1 and 6). New regulatory requirements will likely have the broadest and most substantial impact on primary coagulant use (Chapter 3). The Interim Enhanced Surface Water Treatment Rule (IESWTR) and Stage 1 Disinfectant and Disinfection Byproducts Rule (Stage 1 DBPR) will make finished water requirements more stringent to address microbial removal and the impacts of disinfection. Enhanced Coagulation and/or other operational and treatment practices will be used to achieve these requirements. The science of coagulation (Chapter 4) requires a special focus to address the intricacies of coagulation chemistry. The manual provides a step-by-step methodology to conduct a coagulant changeover using a detailed protocol (Chapter 5) -- background, executive summary.

Resource Recovery in Drinking Water Treatment concentrates on techniques and methods for water purification. The book develops a new approach—resource recovery—toward drinking water, including the role of methods (adsorption, membrane, ion – exchange, biosorption, coagulation, etc.) and nanocomposites (such as biochar, sludge-based composites, chitosan, polymer, magnetic particles, etc.) in water resource recovery. It provides an in-depth overview on emerging water treatment techniques and the resource recovery of materials during the treatment process. Finally, the book aims to introduce polluted waters as new and sustainable sources rather than seeing wastewaters only a source of hazardous organic and inorganic matters. This book is part of a three-volume set that stresses the importance of contaminated water remediation, including surface waters, municipal or industrial wastewaters, and waters as a new source of nutrients, minerals and energy. Presents novel approaches to recover materials from water during treatment Discusses fundamentals and principals of water treatment to figure out current status and need for new development Includes applications of various composites and particles in water treatment and water recovery
