Discussion
The effluent turbidity standard deviations for both the top and bottom positions have a large range (Figures 1 and 2), and there is a trend of increasing standard deviations as the settling state time increases. The maximum standard deviation for the effluent turbidity when the turbidimeter was in its standard position (top) is 12.4. The maximum standard deviation for the effluent turbidity when the turbidimeter was in its new position (bottom) is 14.2. As expected, the influent turbidity standard deviations in both positions are consistently lower than the effluent turbidity standard deviations, and maintain at low values. We expect this because the deviations from the mean are a result of large flocs moving in and out of the sample volume.
