Chemical metal finishing industry

Kuo-Ching Ma obtained his Ph.D. from Florida State University, M.Sc. from The University of Saskatchewan, and B.Sc. from The National Taiwan University, all in Physical Chemistry. After working many years in the aerospace, battery research, fine chemicals, and metal finishing industries in Canada as a Research Scientist, Technical Supervisor/ Director, he is now dedicating his time and interests to environmental research. [Pg.925]

Recycling and resource recovery includes technologies that either directly use waste from one process as raw material for another process or recover valuable materials from a waste stream before the waste is disposed of. Some of the spent chemical process baths and much of the rinsewater can be reused for other plant processes. Also, process chemicals can be recovered from rinsewaters and sold or returned to the process baths. This section describes some of the recycling and resource recovery technologies available to the metal finishing industry. [Pg.61]

Reverse osmosis also serves some of the waste management and resource recovery needs in the metals and metal finishing industry. Effluent streams from mining and plating operations containing heavy metals, acids, and other chemicals can be treated with reverse osmosis to recover both the metal as its salt, and purified water for reuse. For metal ion recovery from dilute solutions, however, reverse osmosis faces competition from conventional solvent extraction, membrane-based solvent extraction, and its variant, coupled transport (see Section V.F.3). [Pg.381]

MFFP2T allows the metal finishing industry to evaluate various process modifications to reduce the quantity and environmental impact of wastes generated. The environmental impact packages developed as part of MFFP2T can be used to analyze similar processes that support the CAPE-OPEN interfaces, expanding the applicability of these environmental impact packages to the chemical and allied industry. [Pg.574]

In recent years, membrane separations have been applied in various industries, such as chemical, food, pharmaceutical, automobilemanufacturing, and metal-finishing industries. As the most popular membranes, polymeric membranes still have an inherent drawback— the... [Pg.218]
