W. H. Dresher to Dr. Henry Chitwood on Asbestos as an Oxidation Catalyst in Sewage Treatment, with Enclosed Report (1964)

Internal correspondence in which W. H. Dresher told Henry Chitwood of experiments in which Union Carbide's asbestos catalyzed oxidation of potassium iodide and appeared to improve activated sludge sewage plants. He enclosed a report dated May 15, 1964, "Aeration Catalyzed by Asbestos," which compared Coalinga and Quebec asbestos in sodium sulfite oxidation tests, and he asked for comment on other possible uses, including as a high-temperature oxidation catalyst.
