Data are reported on the results of tests to determine the range of acceptable construction materials for all unit operations of a chemical plant waste disposal facility. The investigation presented illustrates the corrosion problems encountered in the biological treatment of chemical wastes, stream pollution abatement. The tests were conducted in a pilot plant installed to study the manner in which wastes could be treated on a continuous basis. This activated sludge plant and oxidation pond handled the liquid wastes from a major chemical plant along with those from an oil refinery, zinc plant, casting plant metals reclaiming operation, rubber reclaiming plant, fertilizer plant and domestic sewage. The corrosion study, directed toward criterion requirements for the design and economical maintenance of a full scale, operational secondary waste treatment plant, concludes with recommendations for construction materials. 2.3.8
