Abstract

In the wake of the Millennium Declaration and the Johannesburg resolutions, many countries have begun to address or re-write their policies regarding water supply and wastewater disposal. The goal is to provide high-quality drinking-water for more people and to safely dispose of spent waters from a large portion of the population than today. This book, as its predecessors, provides information and technical solutions to accomplish this mammoth task. It is the outcome of collective experience and know-how exchanged between experts in the field of water technology from all over the world: from the Americas, from central and southern Africa, from Europe and from different parts of Asia.  The Chemical Water and Wastewater Treatment Series provides authoritative coverage of the key current developments in the chemical treatment of water and wastewater in theory or practice and related problems such as sludge production and properties, and the reuse of chemicals and chemically-treated waters and sludges.  Chemical Water and Wastewater Treatment VIII is a valuable resource for managers, scientists, plant operators and others interested in chemical water and wastewater treatment technology.
