to define the distance from the inflow pipe to the decanter (Figure 4.19). The length of the SBR is thendivided into the three equal sized zones. This error was discovered near the end of the calibration ofBNR-S1 mode and the width parameter was corrected. Next, an analysis was completed on the regularmode calibration and BNR-S1 calibration to identify any differences in effluent parameters caused by thechange in width.Figure 4.19 - Flow distribution in single tank SBR (from BioWin user manual)4.4.1 Effects on Regular ModeNo significant changes in effluent parameters for the regular mode with default and calibrated simulatorparameter settings were observed after correcting the width to 13.8 m (Table 4.12). Based on theseresults, it was determined that the change 1.2 m in width had no significant effects on the regular mode.Table 4.12- Width adjustment effects on regular mode effluent quality aWidth (m) TSS pH cBOD TN NH 3-N NO 2 - -N NO 3 - -N TP COD F.
