Ozone in Water Treatment: Application and EngineeringBruno Langlais, David A. Reckhow, Deborah R. Brink Routledge, 2019 M07 16 - 592 pages 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. |
