Study of Pharmaceutical Manufacturing Wastewater Characteristics and Aerated Treatment System DEWEY R. ANDERSEN, Assistant Professor MARK J. HAMMER, Professor JEROME G. OBRIST, Graduate Student Department of Civil Engineering University of Nebraska Lincoln, Nebraska LELAND E. DANIELS, Staff Engineer U. S.,Public Health Service Cincinnati, Ohio CHARLES D. TURNER, Sanitary Engineer City of Lincoln Lincoln, Nebraska INTRODUCTION The characteristics and treatability of wastewaters from pharmaceutical manufacturing and processing plants vary considerably depending upon the type of products being produced. Treatment of these wastewaters is complicated by the variability in the wastewater characteristics and by the nature of many of the products produced. The material presented in this paper was obtained from a study which was made of the wastewaters and the aerated treatment system for Dorsey Laboratories, a pharmaceutical formulation plant located at Lincoln, Nebraska. The Dorsey Laboratories plant is located a considerable distance from a municipal sanitary sewer system. As a result, all wastewaters from the plant, except for cooling and boiler water, are treated in an extended aeration system prior to discharge to a receiving stream. The wastewaters include sanitary wastes, wastes from a company operated cafeteria, and wastes from production and cleanup operations. Wastewater from cooling and boiler operation is discharged to a holding pond which also serves as an emergency source of water for fire fighting purposes. The pharmaceutical products produced at Dorsey Laboratories are primarily the non-prescription type and may be in either the liquid or tablet form. Their uses include sedatives, digestive aids, and medication for arthritis, coughs, colds, hay fever, and sinus and bacterial infections. Production is on a batch basis and the type product produced varies from day to day. The plant employs approximately 225 people and generally operates on a single shift, 40 hr, five-day week. The treatment system consists of a factory-built extended aeration plant. It is not provided with facilities for wasting excess sludge nor for the positive return of sludge to the aeration basin, however, slots or channels are provided for sludge -26-
