With this book, you can compare disinfection options consistently, taking into account operational issues, process and supply-chain reliability, environmental issues, and security considerations. The guide will help you evaluate disinfectants that meet your utility's needs from both a water-quality and a security perspective. The book provides tables that let you compare various disinfectants side-by-side. The tables list the advantages, disadvantages, typical uses, effectiveness, regulations, relative costs, safety and security considerations, and other relevant parameters, for free chlorine (gas, sodium or calcium hypochlorite, on-site generated hypochlorite)chloraminesultraviolet light ozonechlorine dioxideSafety and security have become key considerations for water and wastewater utilities in choosing disinfectants.
