Effluent characteristics for BNR-S1 mode with calibrated simulator parameters are given in Table 4.7. Allsimulator effluent parameters fall within 20% error of observed values with one exception, NH 3 -N whichhas an error of -21.8%. However, this is only a difference of 0.3 mg/L.Table 4.7- BNR-S1 mode effluent quality for calibrated simulator parametersTSS pH cBOD TN NH 3-N NO 2 - -N NO 3 - -N TP COD F.

Significant deviations were found foreffluent TSS, TN, NH 3 -N, NO 2 — N, NO 3 — N, and TP. These results indicate that calibrated BNR-S1 simulatorparameters increase deviation between observed and predicted values over default simulatorparameter values. The sum absolute value of percent deviation increases from 298 for default simulatorparameter values to 516 for BNR-S1 calibrated simulator parameter values.Table 4.9- BNR-S2 (20.1 o C) mode calibrated effluent qualityTSS pH cBOD TN NH 3-N NO 2 - -N NO 3 - -N TP COD F.
