Degradation of Estrogens in Sewage Treatment Processes

Figure 0-3: The oxygen demand of the sludge suspension was sampled at the beginning of each day of the experiment and measured in a 24 h period. It is seen that the biodegradation activity of the active sludge suspensions did not change much between the three days of the experiment. However, the activity varies between sludge suspensions taken from the aerated and the denitrifying batch experiments.
