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.

Covering the latest developments in themes related to water disinfection by-products, this book brings the academic and industry researchers right up to date.

The research reported on here sought to characterize natural organic matter (NOM) in dilute solutions and to isolate it without altering its properties, so that the effect of NOM in drinking water may be considered. Several NOM isolation methods were evaluated, including evaporation, reverse osmosis, nanofiltration, and adsorption. The effects of such isolation procedures on NOM's chemical composition and reactivity were considered. Based on these studies, the report presents conclusions regarding the feasibility and adequacy of in situ and ex situ techniques.

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.

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

Disinfection Byproducts in Drinking Water: Detection and Treatment presents cutting-edge research on how to understand the procedures, processes and considerations for detecting and treating disinfection by-products from drinking water, swimming pool water, and wastewater. The book begins with an overview of the different groups of Disinfection Byproducts (DBPs), such as: Trihalomethanes (THM), Halo acetic acids, and Haloacetonitrile (HAN). This coverage is quickly followed by a clear and rigorous exposition of the latest methods and technologies for the characterization, occurrence, formation, transformation and removal of DBPs in drinking water. Other chapters focus on ultraviolet-visible spectroscopy, electron spin resonance, and gas chromatography-mass spectrometry. Researchers will find a valuable resource to a breath of topics for DBP detection and treatment, including various recent techniques, such as microfiltration, nanofiltration membrane and nanotechnology. Explains the latest research in detection, treatment processes and remediation technologies Includes sampling, analytical and characterization methods and approaches Covers cutting-edge research, including membrane based technologies, nanotechnology treatment technologies and bioremediation treatment technologies Provides background information regarding contamination sources
