| Abstract |
Static acute, unaerated, toxicity tests using fathead minnows and Daphnia magna and a bacterial toxicity assay, Microtox(TM), were conducted on samples of influent and effluent from two conventional activated sludge pilot wastewater treatment systems. The two pilot treatment systems (A and B) were constructed and operated in an identical manner except that a mixture of 16 volatile priority pollutants was continuously added to the influent of the experimental, B system. The common, unspiked influent for both systems was a mixed industrial and domestic wastewater. The toxicity tests were performed on the influent, primary effluent, and secondary effluent samples to determine the acute toxicity of the various samples and to compare the reduction in toxicity across the two treatment systems. The results of these tests indicated that there was no difference in toxicity reduction between the two pilot treatment systems at the level of pollutants added. |

Static acute, unaerated, toxicity tests using fathead minnows and Daphnia magna and a bacterial toxicity assay, Microtox(TM), were conducted on samples of influent and effluent from two conventional activated sludge pilot wastewater treatment systems. The two pilot treatment systems (A and B) were constructed and operated in an identical manner except that a mixture of 16 volatile priority pollutants were continuously added to the influent of the experimental, B system. The common, unspiked influent for both systems was a mixed industrial and domestic wastewater. The volatile priority pollutants were added to system B to obtain a nominal concentration of 50 [mu]g/l each. The toxicity tests were performed on the influent, primary effluent, and secondary effluent samples to determine the acute toxicity of the various amples and to compare the reduction in toxicity across the two treatment systems. The results of these tests indicated that there was no difference in toxicity reduction between the two pilot treatment systems at the level of pollutants added. Toxicity for pairs of similar samples, influent a and B, primary effluent A and B, and secondary effluent A and B, was essentially the same. Even the influent samples, where the highest concentration of pollutants would be expected in the B samples, was not different. |
