# In quest of cleaner air and water

Describes the steel industry's progress, programs, and research in air and water pollution control. Shows the various types of pollution control procedures and equipment used throughout the steel manufacturing process, including dust catchers, air cleaning systems, furnace air control systems, separators, cooling towers, and waste lagoons. Explains how airborne pollutants are precipitated away before air is returned to the atmosphere through the basic oxygen process, and how oil, sludge, and particulate matter are separated before water is returned to the mill or discharged.
