This research project investigated the degree to which the activated sludge wastewater treatment process is inhibited by high carbon dioxide concentration. This report presents the specific methods utilized in the performance of this research and the results obtained. Experiments were done in a CO/sub 2/ rich environment, using a modified large volume respirometer. Due to operating difficulties encountered when the respirometer was modified for elevated CO/sub 2/ concentrations, inhibition was measured by comparing rate of substrate removal in the experimental respirometer with that of the control. After calibrating the experimental method with known substrates and inhibitors, a number of experiments with high CO/sub 2/ concentrations were conducted. 3 refs., 5 figs., 3 tabs.
