Book Description
Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total £119! The overall aim of Elimination of Micro-organisms by Water Treatment Processes is to present default values for the micro-organisms elimination or inactivation credit of universally used processes in water treatment (MEC or MIC). The growing interest in Quantitative Microbial Risk assessment (QMRA) for safe drinking water requires such data. These MEC or MIC values have been calculated from research on elimination of viruses, bacteria and bacterial spores and protozoa (oo)cysts (Cryptosporidium and Giardia) by these treatment processes published in the international literature. The data have been selected on the base of different quality criteria related to information on applied experimental conditions and used methods. Furthermore the studies have been categorized on base of their similarities with ‘real world’ conditions (selected micro-organisms, scale and conditions of the tested processes). The international literature data revealed a high variation in elimination. The major parameters and process control parameters affecting elimination are described. This new edition describes the state-of-the-art progress in research on conventional treatment, coagulation and flocculation, rapid granular filtration, slow sand filtration and UV disinfection.

Book Description
Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total £119! Ever since the recognition of the important role of water in the transmission of pathogenic micro-organisms in the 19th century, microbiological safety of drinking water has been a major research issue for microbiologists in the drinking water industry. The main objective of this book is to develop a general strategy to assess elimination capacity of water treatment processes for pathogens. It investigates: The potential use of faecal indicators Coli44, (including E. coli) and SSRC, (including C. perfringens) as process indicators to assess pathogen elimination in full-scale water treatment plants. The value of comparative challenge tests with pre-cultured organisms for the assessment of elimination capacity of full-scale processes, to study the effect of process conditions and to validate the use of process indicators. The use of literature data to assess elimination capacity of water treatment processes for pathogens and the effect of process conditions on this.

Book Description
This report reviews the various water treatment technologies available to remove micro-organisms from raw water supplies. Discussions of each technology includes a process overview, performance information, design considerations, operating and maintenance aspects, and notes on costs and status of technology development. In addition, the impacts of important micro-organisms and relevant regulations are examined to highlight the significance and requirements of removing micro-organisms from water treatment processes. Specific consideration is made regarding those technologies suitable for small community systems located in the Northern River Basins Study area. Types of technologies examined include pre-filtration processes such as coagulation and sedimentation, filtration, and disinfection. Three types of package plants (conventional, tube-type clarification, and adsorption clarifier) suitable for small communities are also reviewed.

Book Description
Prepared by the Water Supply Engineering Technical Committee of the Infrastructure Council of the Environmental and Water Resources Institute of ASCE. This report provides a comprehensive survey of the state of the art in drinking water treatment methods and technologies for controlling microorganisms. Academics, practicing engineers, and environmental scientists offer insight into the risks posed by microbes in drinking water and ,more importantly, their control through treatment and disinfection. The report supplies an overview of the subject for nonspecialists and becomes a valuable technical reference for experienced practitioners. Topics include: Ørisks posed by pathogens in drinking water; Ømicrobially-mediated corrosion and water quality deterioration; Øindicator concept and its application in water supply; Øremoval of organisms by flocculation/sedimentation; Øair stripping and aeration; Øslow sand filtration; Ørapid sand filtration; Øgranular activated carbon/biological activated carbon; Øcontrol of microorganisms in drinking water by pressure-driven membrane processes; Øgeneral kinetics of disinfection processes; Øchlorine and chloramines; Øchlorine dioxide in drinking water treatment; Øultraviolet disinfection; Øozone disinfection in drinking water; and Øemerging pathogens of concern in drinking water.

Book Description
Water is our natural heritage, our miracle of life. However, our increasingly technological society has become indifferent to water. Far from being pure, modern drinking water around the world contains many undesirable chemical and bacterial contaminants. The existing techniques employed for the disinfection of water are either energy-intensive or have by-products harmful to human health. Drinking Water Disinfection Techniques reviews these processes and explores novel technologies for water disinfection synergistic with existing techniques. The book covers a wide audience and gives a comprehensive review of various physical, chemical, and hybrid techniques commonly used for the disinfection of water as well as newer emerging technologies in terms of their mode of action, scale of operation, efficacy, merits, and demerits. It broadly addresses the issues related to water disinfection in three sections: Disinfection techniques—chemical, physical, and hybrid (combination)—and their likely scale of operation efficacy Disinfection by-product as a function of water source and the type of treatment Emerging and novel techniques, including new work on cavitation, an economical, energy-efficient, and simple alternative to the conventional methods of disinfection Drinking Water Disinfection Techniques effectively combines the chemical, physical, biological, and engineering principles of water disinfection in one text. Discussing both conventional and novel techniques used for disinfection and the economics involved, the book gives a comprehensive review of various physical, chemical, and hybrid techniques used for disinfection to create potable water.

Book Description
"Access to safe water is a fundamental human need and therefore a basic human right" --Kofi Annan, United Nations Secretary General Edited by two world-renowned scientists in the field, The Handbook of Water and Wastewater Microbiology provides a definitive and comprehensive coverage of water and wastewater microbiology. With contributions from experts from around the world, this book gives a global perspective on the important issues faced in the provision of safe drinking water, the problems of dealing with aquatic pollution and the processes involved in wastewater management. Starting with an introductory chapter of basic microbiological principles, The Handbook of Water and Wastewater Microbiology develops these principles further, ensuring that this is the essential text for process engineers with little microbiological experience and specialist microbiologists alike. Comprehensive selection of reviews dealing with drinking water and aquatic pollution Provides an understading of basic microbiology and how it is applied to engineering process solutions Suitable for all levels of knowledge in microbiology -from those with no background to specialists who require the depth of information
