1 Industrial city (1990 pop. 23,622), Boyd co., E Ky., on terraces along the Ohio River near the influx of the Big Sandy; settled 1786, inc. 1854. Specialty Chemicals A Specialty chemical is a chemical produced for a specialized use. They are produced in lower volume than bulk chemicals, of which petrochemicals, made from oil feedstocks, are the most common. However, both are produced in a chemical plant. Drew Industrial Div. has introduced its Performax Millennium series of cooling water treatment programs. These products are multi-functional formulations that typically provide 90% reduction in corrosion and scale in open recirculating and once-through cooling water systems. Biodegradable biodegradable /bio·de·grad·a·ble/ (-de-grad´ah-b'l) susceptible of degradation by biological processes, as by bacterial or other enzymatic action.
