This book presents the state-of-the-art of metals treatment and recovery technologies to assist in identifying waste management options for metal-bearing sludges and wastewaters. Nine metal-waste producing industries are discussed: metal coatings, smelling and refining of nonferrous metals, paint and ink products, petroleum refining, iron and steel manufacturing, photographic industry, leather tanning, wood preserving, and battery manufacturing. These industries were selected because of the high metal concentrations associated with the sludges and wastewaters generated by plants within each of these industry segments. The techniques presented here are also applicable to metal-bearing waste streams in all other industries.
The Resource Conservation and Recovery Act (RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984, prohibits the placement of untreated wastes in or on the land. The land disposal prohibitions are waived if the hazardous wastes intended for disposal ate treated such that they do not exceed a maximum concentration of hazardous constituents set by EPA or if the wastes are treated using a treatment method set by EPA.
The focus of the book is on established rather than emerging technologies, in order to provide useful information on immediately available technologies to industry. Metals treatment and recovery technologies addressed include chemical precipitation, electro winning, high temperature metals recovery, membrane separation, leaching, adsorption, and evaporation. For each of these technologies, a discussion of the following parameters is included: design specifications of applicable processes, waste characteristics affecting performance, pretreatment/post-treatment requirements, available performance data, availability of the technology and feasibility for treating wastes, environmental impact/residue management, and cost-effectiveness.

The table of contents is organized in such a way as to serve as a subject index and provides easy access to the information contained in the book.
Advanced composition and production methods developed by Noyes Data Corporation are employed to bring this durably bound book to you in a minimum of time. Special techniques are used to close the gap between "manuscript" and "completed book." In order to keep the price of the book to a reasonable level, it has been partially reproduced by photo-offset directly from the original report and the cost saving passed on to the reader. Due to this method of publishing, certain portions of the book may be less legible than desired.
