Water Works 1990

Papers of the Denver, Colo. meeting in June 1990 address topics apposite to industrial, governmental, and environmental scientists concerned with water quality. Includes chapters on radiochemical analysis, inorganic constituents of water, methods for organics detection, sediments, microbiology, oil.

This second edition demonstrates how chemistry influences the design of water treatment plants and how it should influence the design. Historically, water treatment plants have been designed from hydraulic considerations with little regard to chemical aspects. The many chemical reactions used for removal of pollutants from water simply cannot be forced to occur within current designs. This book re-examines this traditional approach in light of today's water quality and treatment. Will current water treatment processes be sufficient to meet future demands or will new processes have to be devised? Chemistry of Water Treatment assesses the chemical and physical efficacies of current processes to meet the demands of the Safe Drinking water Act, providing expert information to persons responsible for the production of potable water into the next century.

This book is the most comprehensive empirical study to date of the social and technical aspects of milling during the ancient and medieval periods. Drawing on the latest archaeological evidence and historical studies, the book examines the chronological development and technical details of handmills, beast mills, watermills and windmills from the first millennium BCE to c. 1500. It discusses the many and varied uses to which mills were turned in the civilisations of Rome, China, Islam and Europe, and the many types of mill that existed. The book also includes comparative regional studies of the social and economic significance of milling, and tackles several important historiographical issues, such as whether technological stagnation was a characteristic of late Antiquity, whether there was an "industrial revolution" in the European Middle Ages based on waterpower, and how contemporary studies in the social shaping of technology can shed light on the study of pre-modern technology.

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.
