Ozone in Water Treatment


Book Description

With the advent of the Safe Drinking Water Act Amendments of 1986, many water utilities are reexamining their water treatment practices. Upcoming new regulations on disinfection and on disinfection by-products, in particular, are the primary driving forces for the big interest in ozone. It appears that ozone, with its strong disinfection capabilities, and apparently lower levels of disinfection by-products (compared to other disinfectants), may be the oxidant/disinfectant of choice. Many utilities currently using chlorine for oxidation may need to switch due to chlorine by-product concerns. Utilities using chloramines may need to use ozone to meet CT requirements. This book, prepared by 35 international experts, includes current technology on the design, operation, and control of the ozone process within a drinking water plant. It combines almost 100 years of European ozone design and operating experience with North American design/operations experience and the North American regulatory and utility operational environment. Topics covered include ozone chemistry, toxicology, design consideration, engineering aspects, design of retrofit systems, and the operation and economics of ozone technology. The book contains a "how to" section on ozone treatability studies, which explains what information can be learned using treatability studies, at what scale (bench, pilot, or demonstration plant), and how this information can be used to design full-scale systems. It also includes valuable tips regarding important operating practices, as well as guidance on retrofits and the unique issues involved with retrofitting the ozone process. With ozone being one of the hottest areas of interest in drinking water, this book will prove essential to all water utilities, design engineers, regulators, and plant managers and supervisors.

Electrochemical Water and Wastewater Treatment


Book Description

Electrochemical Water Treatment Methods provides the fundamentals and applications of electrochemical water treatment methods to treat industrial effluents. Sections provide an overview of the technology, its current state of development, and how it is making its way into industry applications. Other sections deal with historical developments and the fundamentals of 18 methods, including coupled methods, such as Electrocoagulation, Peroxi-Coagulation and Electro-Fenton treatments. In addition, users will find discussions that relate to industries such as Pulp and Paper, Pharmaceuticals, Textiles, and Urban/Domestic wastewater, amongst others. Final sections present advantages, disadvantages and ways to combine renewable energy sources and electrochemical methods to design sustainable facilities. Environmental and Chemical Engineers will benefit from the extensive collection of methods and industry focused application cases, but researchers in environmental chemistry will also find interesting examples on how methods can be transitioned from lab environments to practical applications. - Offers an excellent overview of the research advances and current applications of electrochemical technologies for water treatment - Explains, in a comprehensive way, the fundamentals of different electrochemical uses and applications of different technologies - Provides a large number of examples as evidence of practical applications of electrochemistry to environmental protection - Explores the combination possibilities with other treatment technologies or emerging technologies for destroying water pollutants




Ozonation of Water and Waste Water


Book Description

The leading resource on ozone technology, this book contains everything from chemical basics to technical and economic concerns. The text has been updated to include the latest developments in water treatment and industrial processes. Following an introduction, the first part looks at toxicology, reaction mechanisms and full-scale applications, while Part B covers experimental design, equipment and analytical methods, mass transfer, reaction kinetics and the application of ozone in combined processes.







Advanced Oxidation Processes for Water Treatment


Book Description

Advanced Oxidation Processes (AOPs) rely on the efficient generation of reactive radical species and are increasingly attractive options for water remediation from a wide variety of organic micropollutants of human health and/or environmental concern. Advanced Oxidation Processes for Water Treatment covers the key advanced oxidation processes developed for chemical contaminant destruction in polluted water sources, some of which have been implemented successfully at water treatment plants around the world. The book is structured in two sections; the first part is dedicated to the most relevant AOPs, whereas the topics covered in the second section include the photochemistry of chemical contaminants in the aquatic environment, advanced water treatment for water reuse, implementation of advanced treatment processes for drinking water production at a state-of-the art water treatment plant in Europe, advanced treatment of municipal and industrial wastewater, and green technologies for water remediation. The advanced oxidation processes discussed in the book cover the following aspects: - Process principles including the most recent scientific findings and interpretation. - Classes of compounds suitable to AOP treatment and examples of reaction mechanisms. - Chemical and photochemical degradation kinetics and modelling. - Water quality impact on process performance and practical considerations on process parameter selection criteria. - Process limitations and byproduct formation and strategies to mitigate any potential adverse effects on the treated water quality. - AOP equipment design and economics considerations. - Research studies and outcomes. - Case studies relevant to process implementation to water treatment. - Commercial applications. - Future research needs. Advanced Oxidation Processes for Water Treatment presents the most recent scientific and technological achievements in process understanding and implementation, and addresses to anyone interested in water remediation, including water industry professionals, consulting engineers, regulators, academics, students.
