Disinfection Byproducts in Drinking Water by Yuefeng Xie Pdf

The EPA has established regulations which classify four types of disinfection byproducts - TTHMs, haloacetic acids, bromate, and chlorite - and requires public water systems limit these byproducts to specific levels. Most of the information required to comply with these standards is either scattered throughout the literature or derived from confere

Analysis and Formation of Disinfection Byproducts in Drinking Water by Anonim Pdf

Drinking water disinfection has markedly reduced diseases causes by waterborne pathogenic microorganisms. However, an unintended consequence of disinfection and/or oxidation processes is the generation of disinfection byproducts (DBPs) which are formed from the reactions of disinfectants/oxidants with water matrix components. This volume of the Comprehensive Analytical Chemistry Handbook presents recent advances about the formation, identification, and quantification of inorganic and organic DBPs during oxidative processes. The book begins with a first chapter reviewing the most recent non-targeted screening approaches and workflows to characterize DBPs using low-, high-, and ultra-high-resolution mass spectrometry. The second chapter discusses the analysis of inorganic chloramines in waters using on-site and/or in-lab analytical methods. The third chapter provides an overview of the current knowledge about the mechanisms of chlorine dioxide reactions and byproducts formation. The fourth chapter presents some fundamental and practical aspects about ozonation processes in water treatment and provides an overview about ozone reaction mechanisms and byproducts formation. The fifth chapter focuses on the reactivity of halide ions, particularly bromide and iodide, with common oxidants and the role they play in determining the speciation of DBPs in treated waters. The chapter also presents strategies to mitigate the formation of DBPs during oxidation processes. Finally, the last chapter tackles the topic of DBPs formation during potable water reuse. It discusses the formation of DBPs of major concern in both memebrane-based and non-membrane-based potable water reuse treatment schemes. Researchers, water treatment specialists, and regulators will find in this book a valuable and compact resource on several key topics regarding the formation, identification, quantification, and mitigation of DBPs. Identification and quantification of known and unknown DBPs Formation of DBPs during different disinfection/oxidation processes DBPs of concern in new technologies and/or new applications of existing technologies in water treatment

Control of Disinfection By-products in Drinking Water Systems by Anastasia Nikolau,Luigi Rizzo,Hüseyin Selcuk Pdf

The occurrence of disinfection by-products (DBPs) in drinking water has been an issue of major concern during several decades. The formation of many DBPs species during water disinfection has been documented, while new by-products are still being detected, as the analytical instrumentation available becomes more accurate and sensitive. Most of the DBPs have been proven to have toxic effects on living organisms; therefore they pose risks to human health during drinking water consumption. The factors affecting their formation have been extensively investigated, their transport and fate have been studied, modelling efforts for several of them have been performed, in order to understand better their behaviour and therefore try to minimise their occurrence in waters. Techniques for their removal from water have also been applied, and a variety of disinfection methods or combinations of disinfecting agents have been investigated with the aim to produce safe drinking water containing the minimum possible concentrations of DBPs. This book deals with the advances in control of DBPs in drinking water systems. Further than an providing an overview of existing disinfection techniques and by-products, up-to-date information on the parameters affecting the procedures of DBPs formation, analytical methods for their determination, toxicity, regulation, it pays special emphasis on the advanced treatment methods applied recently for DBPs control and presents recent promising findings as well as case studies in this field, as the relevant research is proceeding, producing more knowledge and practical solutions in regard to the disinfected drinking water quality.

Natural Organic Matter and Disinfection By-products Characterization and Control in Drinking Water by Sylvia E. Barrett Pdf

There are many by-products of water disinfection that are still not fully understood and can be potentially harmful. In this volume all the current research in this area is discussed, along with an examination of the role of NOM (natural organic matter) and its relationship to DBP (disinfection by-product) formation and control in drinking water. Understanding the relationship of NOM to DBP may well lead to new techniques for analyzing and treating water and enable reasonable choices to be made for source-water protection, treatment plant process optimization, and distribution system operation to control DBP's. This volume emphasizes the characterization and reactivity of polar natural organic matter. It examines analytical methods which better characterize NOM and determines some of the polar and nonvolatile DBP forms. It presents innovative new methods, sich as capillary electrophoresis for haloacetic aceids and LC/MS for the identification of polar dinking water DBPs.

Disinfection By-Product Formation and Control During Chloramination by Gerald E. Speitel Jr,P. Pope,M. Robin Collins,M. Martin-Doole Pdf

In response to current and anticipated disinfection by-product (DBP) regulations, many utilities have begun to use chloramines as a secondary disinfectant. Chloramination produces DBPs such as haloacetic acids (HAAs), trihalomethanes (THMs), and haloacetonitriles (HANs) in lower concentrations than chlorination. Previous research has demonstrated that dihalogenated haloacetic acids (DXAAs) are the most commonly formed HAAs during chloramination. Some utilities may have difficulty meeting the new maximum contaminant level (MCL) for HAAs because chloramination does not limit the formation of DXAAs to the same extent as it does other DBPs. The objectives of this project were to: better understand the reactivity of key natural organic matter (NOM) fractions and the effects of treatment processes with respect to dihaloacetic acid (DXAA) formation, better delineate the influence of pH and Cl2/N ratio on DXAA formation, characterize DXAA formation kinetics and the impact of treatment processes on the kinetics, especially the impact of prechlorination, calculate the rate and extent of DXAA formation at elevated summer water temperatures, and determine the effect of bromide concentration on DXAA speciation and kinetics.

Water Disinfection and Natural Organic Matter by R. A. Minear Pdf

As part of the effort to balance water treatment processes between allowing pathogenic infection by doing too little, and raising the risk of cancer with by-products of the treatment, 20 papers from a symposium in Chicago, August 1995, present information on the chemical identity of natural organic matter and its interactions with the inorganic precursor bromide ion. They review the history of natural organic matter in water treatment and the impact of regulations, then plunge into reports on an economical experimental approach to developing predictive models for by-products of disinfection, a comparison of analytical techniques for determining cyanogen chloride in chloraminated drinking water, the effect of ozonation and biotreatment on molecular size and hydrophilic fractions of natural organic matter, removing bromate ion by electric-arc discharge and high-energy electron beam processes, and other topics.
