New edition covers the latest practices, regulations, and alternative disinfectants Since the publication of the Fourth Edition of White's Handbook of Chlorination and Alternative Disinfectants more than ten years ago, the water industry has made substantial advances in their understanding and application of chlorine, hypochlorite, and alternative disinfectants for water and wastewater treatment. This Fifth Edition, with its extensive updates and revisions, reflects the current state of the science as well as the latest practices. Balancing theory with practice, the Fifth Edition covers such important topics as: Advances in the use of UV and ozone as disinfectants Alternative disinfectants such as chlorine dioxide, iodine, and bromine-related products Advanced oxidation processes for drinking water and wastewater treatment New developments and information for the production and handling of chlorine Latest regulations governing the use of different disinfectants For each disinfectant, the book explains its chemistry, effectiveness, dosing, equipment, and system design requirements. Moreover, the advantages and disadvantages of each disinfectant are clearly set forth. References at the end of each chapter guide readers to the primary literature for further investigation. Authored and reviewed by leading experts in the field of water and wastewater treatment, this Fifth Edition remains an ideal reference for utilities, regulators, engineers, and plant operators who need current information on the disinfection of potable water, wastewater, industrial water, and swimming pools.

The essential sourcebook on disinfectants for water purification For more than two decades, George Clifford White's handbook has been known as one of the most vital references on all aspects of chlorination, dechlorination, and the use of alternative disinfectants such as chloramines, ozone, bromine, and ultraviolet radiation. This latest edition features expanded and updated material in every chapter-crucial information for professionals in industries ranging from water treatment, toxicology, and food packaging to industrial hygiene, environmental engineering, and paper processing. White shows how to harness the possibilities of chlorine and other disinfectants for purification. He offers detailed coverage of chlorine hazards-including how to cope with major leaks-and provides insightful profiles of chlorine accidents as well as strategies for avoiding them. Handbook of Chlorination and Alternative Disinfectants, Fourth Edition also covers: * Biomedical and environmental effects of chlorine * New advances in equipment, facilities, and operations * The important problem of virus infiltration of water supplies * Chlorine supplies as critical resources, and the issue of their depletion * American and European chlorination practices Handbook of Chlorination and Alternative Disinfectants, Fourth Edition is a key resource for researchers, designers, and equipment manufacturers; an ideal reference for regulatory agencies; and a user-friendly operations manual for technicians.

Public water systems deliver high-quality water to the public. They also present a vast array of problems, from pollution monitoring and control to the fundamentals of hydraulics and pipe fitting.

Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
