In a study conducted for API by Texaco Inc. at the company's Port Arthur, Tex., Class E refinery, short-term (96 h) and long-term (30 day) continuous-flow bioassays on sheepshead killifish were performed to test half-strength and full-strength effluents obtained by each of four different activated sludge unit (ASU) treatments: a conventionally operated ASU plus final filteration; a conventionally operated ASU plus filtration plus granular activated carbon contactors; an ASU to which a blend of commercially available activated carbons was added plus final filtration; and an ASU to which an experimental, noncommercial, high-surface-area, powdered activated carbon was added plus filtration. During normal operation, the fish mortality was too low to indicate significant differences among treatments. During a plant upset, fish mortality was sometimes higher in carbon-treated effluents than in conventionally treated wastewaters. Although not accumulating in the exposed fish, polynuclear aromatics were higher in carbon-treated effluents than in the pretreated refinery wastewater or conventionally treated wastewater. For unknown reasons, cadmium and zinc accumulated in fish exposed to some types of carbon-treated effluents.
