It is hoped that this book will be utilized by the many scientific and engineering disciplines which encounter water quality problems in their professional endeavors. The authors have attempted to provide the essential chemical bases that control the many dissolved constituents in natural waters. Also, a considerable quantity of "raw" water quality data is provided that may be helpful in the management of lakes, reservoirs, streams, rivers, etc., and in the design, perhaps, of a potable water treatment plant. The authors have researched the scientific literature as thoroughly as possible on a particular water quality subject.

The discipline of surface and colloid chemistIy has experienced a considerable resurgence since the early sixties. This perhaps reflects a growing realisation of the wide applicability of modern colloid and surface theory to many important industrial, medical and environmental problems. This increased activity has resulted in a very complex and at times even confusing area of science being consolidated within a firm theoretical framework. The clearer insights gained into the underlying principles have no doubt acted in an autocatalytic manner to stimulate further interest in an expanding range of applications. A good example in the area of environmental chemistry has been the realization of the important role played by colloidal material and surface interactions in natural biogeochemical processes that has been the subject of increasing attention over the last few decades. This is well illustrated by the numerous studies carried out to elucidate the speciation, toxicity, transport and fate of pollutants in aquatic systems. In the vast majority cases these have clearly implicated some involvement of an aSSOciation between the of pollutant (e. g. trace metal, toxic organic compound or nutrient) and a colloidal component (e. g. particle, humic substance, foam). In order to understand these interactions fully and their effect on pollutant mobility it is important to develop a full appreciation of the surface chemistry of these complex systems. Australian SCientists have long been prominent in the area of colloid and surface chemistry particularly dUring the latter half of this century.

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.

The fully revised third edition of this unique and comprehensive overview of the science and technology of the bottled waters industry contains brand new chapters which address these new developments. As well as an updated introductory chapter reviewing the market, the degree to which the global legislative and regulatory picture has changed is examined, and new and increasingly-used quality standards are assessed. The book provides a definitive source of reference for all those involved in bottled water production: beverage technologists, packaging technologists, analytical chemists, microbiologists and health and safety personnel.
