Book excerpt: Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save a total £119! Safe drinking water is a basic need for all human beings. Preventing microbial contamination of drinking water is of primary concern since endemic illness and outbreaks of infectious diseases can have significant social and economic consequences. Confirming absence of indicators of faecal contamination by water analysis only provides a limited verification of safety. By measuring pathogenic organisms in source water and modelling their reduction by treatment, a higher level of drinking water safety can be verified. This book provides stochastic methods to determine reduction of pathogenic microorganisms by drinking water treatment. These can be used to assess the level and variability of drinking water safety while taking uncertainty into account. The results can support decisions by risk managers about treatment design, operation, monitoring, and adaptation. Examples illustrate how the methods can be used in water safety plans to improve and secure production of safe drinking water.

Available in PDF, EPUB and Kindle. Book excerpt: Special Offer: KWR Drinking Water Treatment Set - Buy all five books together and save £119! Computational Fluid Dynamics (CFD) uses advanced numerical models to predict flow, mixing and (bio)-chemical reactions. In drinking water engineering, CFD is increasingly applied to predict the performance of treatment installations and to optimise these installations. A lack of understanding of the hydraulics in drinking water treatment systems has resulted in suboptimal design of installations. The formation of unwanted disinfection-by-products and the energy consumption or use of chemicals is therefore higher than necessary. The aim of this work is to better understand the hydraulic and (bio)-chemical processes in drinking water treatment installations using experimental and numerical techniques. By combining these techniques, CFD modelling is further developed as a tool to evaluate the performance of these installations. This leads to new insights in the applicability of models in ozone and UV systems, and new insights in design concepts of these systems. CFD modelling proves to be a powerful tool to understand the hydrodynamic and (bio)-chemical processes in drinking water systems. If applied properly, accounting for the complex turbulent motions and validated by experiments, this tool leads to a better design of UV reactors, ozone systems and other systems dictated by hydraulics.

Book excerpt: 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.

Download or read book Microbial Source Tracking Methods Applications and Case Studies written by Charles Hagedorn and published by Springer Science & Business Media. This book was released on 2011-06-08 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the origin of fecal pollution is essential in assessing potential health risks as well as for determining the actions necessary to remediate the quality of waters contaminated by fecal matter. As a result, microbial source tracking (MST) has emerged as a field that has evolved and diversified rapidly since the first approaches were described only a decade ago. In response to the emergence of MST, there have been three large multi-laboratory method comparison studies (two in the US and one in Europe), plus numerous workshops, book chapters, and review articles dedicated to synthesizing information on the topic. Furthermore, a federal (USEPA) guide document describing the uses and limitations of MST methods was published in 2005, and a book dedicated to MST as an emerging issue in food safety was published in 2007. These documents provide a collective body of literature on MST that is both conflicting and complementary, often repetitious, and difficult to condense and interpret. In addition, it does not reflect the current diversity of MST approaches with different organisms, newer methodologies such as quantitative PCR, and anthropogenic chemicals, nor does it embrace the scope of MST research being conducted around the world. The three editors of the book, all with extensive MST expertise, have developed chapters and invited authors who reflect the rich diversity and truly international scope of MST. The unifying theme throughout the book is the design of more standardized approaches to MST that include performance criteria (regardless of method or organism), plus recommendations for field study design and MST implementation. The editors intend that this book will serve as a valuable reference for all those who are involved with
Download or read book Assessing Microbial Safety of Drinking Water written by A. Dufour and published by IWA Publishing. This book was released on 2003-11-01 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inadequate drinking water quality and poor sanitation have remained the world's major causes of preventable morbidity and mortality. In 1996 the OECD called for concerted action to improve the assessment and management of the world's sources of drinking water. This guidance document seeks to respond to this call. It is the product of a shared initiative between the OECD and the World Health Organization. It is a state-of-the-art review that will contribute to the revisions of the WHO's Guidelines for Drinking Water Quality. Assessing Microbial Safety Of Drinking-water has elements of both revolution and evolution. It is revolutionary in that it supports a rapidly emerging approach for a broader, system-wide management perspective. This is based on a risk management framework that has evolved from the traditional indicator concept to include multiple parameters and where consideration is also given to tolerable risk, water quality targets and public health status.

This book was released on 2014 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In drinking water treatment, a balance must be maintained between the highest microbial safety, while limiting the long term chemical risk from disinfection by-products. To achieve this, Quantitative Microbial Risk Assessment (QMRA) models are used to attain a level of acceptability in engineering and public health. Models for QMRA are being increasingly used internationally by regulatory agencies. The objective of applying these models is to help define when safe is 'safe enough.' It is a systematic and science-based approach to warrant that systems will deliver safe water and efficient safety management"--Page 1.

Download or read book Wastewater Recycling Reuse and Reclamation Vol I written by Saravanamuthu Vigneswaran and published by EOLSS Publications. This book was released on 2009-11-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Total supply of fresh water on earth far exceeds human demand. However, scarcity of water currently faced in many regions of the world is caused by two reasons. First, its availability in time and space is not equally distributed. Thus there is problem of water in the wrong place, or at the wrong time and in wrong quantities. Second, while the population growth and expanded industrial activities are increasing demands on available water resources, they also jeopardize the availability of freshwater in adequate quantities by discharge of pollutants into freshwater sources. It is at times like these, when the rising curve of water demand intersects the fluctuating curve of water availability, recycle and reuse of wastewater is seriously considered. Wastewater recycling, reuse and reclamation have been, now, accepted as appropriate ways to conserve water resources as well as to contain polluted waters from contaminating other available clean water sources. This book gives a comprehensive review on water quantity and quality, simple water supply and sanitation systems, and leads to domestic, agricultural and industrial water reuse. Thus, it will provide useful information not only to technologists but also for planners, managers, and NGOs involved in the water sector. The contribution to the book comes from a broad pool of experts, working on technology, policy, health, and economy aspects of water management. Involvement of both academics and industry personnel from developing and developed countries makes this contribution broader and useable for a wide readership.
