The Nalco Water Handbook

With the nation looking toward a goal of ``zero discharge'' in water pollutants by the early 1980s, this timely handbook is an ideal source of information for specialists and nonspecialists alike. It provides completely practical data and techniques in the four major water conservation and use areas: (1) water chemistry, sources, and contaminants; (2) unit operations and treatment; (3) industrial and municipal use of water and its disposal; and (4) special technology in water treatment.
