"This book provides a comprehensive presentation of theory, methods, and contemporary and emerging applications of ultraviolet (UV) radiation. The first four chapters of the book provide fundamental information regarding the history and laws of photochemistry and photochemical reactions, the dynamic behavior of UV-based reactor systems, and the physical concepts that govern natural and man-made source of UV radiation. Chapters 5-8 address numerical and empirical methods that are used to evaluate photochemical kinetics, photobiological kinetics, and the dynamics of UV photoreactors. The remaining chapters address common and emerging applications of UV radiation, including disinfection of water and wastewater, UV-induced transformation processes (direct photolysis, advanced oxidation processes, and advanced reduction processes), as well as disinfection of air and surfaces."-- Provided by publisher.
