Haloforms and Related Compounds in Drinking Water


Book Description

Drinking water quality has been a matter of concern for several decades. Disinfection of drinking water improves its microbiological quality and prevents disease outbreaks. However, continuously increasing scientific research concerns the presence of organic and inorganic contaminants in water. Many of these compounds, named haloforms, originate from the procedure of disinfection, being formed during reactions of disinfectants with natural organic matter present in water. Haloforms may possess carcinogenic or mutagenic properties; therefore minimization of their concentrations in drinking water is a critical issue. Regulatory measures are becoming more and more stringent, as new health effects become known and optimized high-sensitivity analytical methodologies are being developed. Up-to-date research findings concerning all these aspects have been collected, critically reviewed, summarized, and are presented and discussed in the present book.




Environmental Chemistry


Book Description

This book describes advances in this new, fast developing science, which seeks to decipher fundamental mechanisms ruling the behaviour in water, soils, atmosphere, food and living organisms of toxic metals, fossil fuels, pesticides and other organic pollutants. Sections on eco-toxicology, green chemistry, and analytical chemistry round out this thorough survey of conditions and analytical techniques in an emerging specialty.

Determination of Toxic Organic Chemicals In Natural Waters, Sediments and Soils


Book Description

Determination of Toxic Organic Chemicals in Natural Waters, Sediments and Soils: Determination and Analysis reviews the latest techniques for the determination and assessment of both current and emerging organic compounds in a range of important environmental contexts. A wide range of organic compounds in non-saline waters are discussed in the opening chapters, including hydrocarbons, surface active agents and volatile organic compounds. This is followed by multiorganics, pesticides and organometallic compounds in non-saline waters. Organic compounds in aqueous precipitation are then explored before the book goes on to discuss compounds in soils, including extraction techniques, insecticides, herbicides and fungicides, and organometallic compounds. Finally, the concluding chapters focus on compounds in sediments, providing readers with the latest information in the field and supporting them as they address the important issue surrounding organic material throughout ecosystems. - Highlights the latest methods for analyzing a wide range of organic compounds - Supports researchers by providing detailed information across a range of ecosystems - Includes detailed guidance for assessing complex mixtures of organic compounds in the environment

Taste and Odour in Source and Drinking Water


Book Description

This book provides an updated evaluation of the characterization and management of taste and odour (T&O) in source and drinking waters. Authored by international experts from the IWA Specialist Group on Off-flavours in the Aquatic Environment, the book represents an important resource that synthesizes current knowledge on the origins, mitigation, and management of aquatic T&O problems. The material provides new knowledge for an increasing widespread degradation of source waters and global demand for high quality potable water. Key topics include early warning, detection and source-tracking, chemical, sensory and molecular diagnosis, treatment options for common odorants and minerals, source management, modelling and risk assessment, and future research directions. Taste and Odour in Source and Drinking Water is directed towards a wide readership of scientists, engineers, technical operators and managers, and presents both practical and theoretical material, including an updated version of the benchmark Drinking Water Taste and Odour Wheel and a new biological wheel to provide a practical and informative tool for the initial diagnosis of the chemical and biological sources of aquatic T&O.




Disinfection By-products in Drinking Water


Book Description

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




Emerging Trends in Engineering, Science and Technology for Society, Energy and Environment


Book Description

The International Conference on Emerging Trends in Engineering, Science and Technology (ICETEST) was held at the Government Engineering College, Thrissur, Kerala, India, from 18th to 20th January 2018, with the theme, “Society, Energy and Environment”, covering related topics in the areas of Civil Engineering, Mechanical Engineering, Electrical Engineering, Chemical Engineering, Electronics & Communication Engineering, Computer Science and Architecture. Conflict between energy and environment has been of global significance in recent years. Academic research needs to support the industry and society through socially and environmentally sustainable outcomes. ICETEST 2018 was organized with this specific objective. The conference provided a platform for researchers from different domains, to discuss and disseminate their findings. Outstanding speakers, faculties, and scholars from different parts of the world presented their research outcomes in modern technologies using sustainable technologies.




Chemistry of Water Treatment, Second Edition


Book Description

This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.
