Adjustments of -10% to -30% give a TSS value with less than 20% error. A value of-25% of the default value for maximum Vesilind settling velocity was selected because this parametervalue gave the smallest amount of error in effluent TSS.58

Vesilind settling velocityFigure 4.16 - Effluent TSS calibration for BNR-S1 mode by adjustment of maximum Vesilind settlingvelocity (0% represents default maximum Vesilind settling velocity value in simulator)The substrate (NH 4 + ) half-saturation concentration was adjusted to correct the effluent NH 3concentration. A side effect of adjusting the substrate (NH 4 + ) half-saturation concentration is asignificant decrease in the effluent NO 3 concentration (Figure 4.17). This decrease in effluent NO 3 - -Nresults in an increase in percent error for NO 3 - -N. A choice needed to be made between minimizing theerror in NH 3 -N while increasing the error of another NO 3 - -N versus minimizing the error in bothparameters, but the error in NH 3 -N to a lesser extent than the first option. The latter was chosenbecause it placed the error in both NH 3 -N and NO 3 - -N below 20%.504540353025201510500% 20% 40% 60% 80% 100%Percent adjustment of substrate (NH 4+ ) half-saturationconcentrationNH3NO3Figure 4.17 - Effluent NH 3 -N concentration calibration for BNR-S1 mode by adjustment of AOB substratehalf-saturation concentration (0% represents default substrate (NH 4 + -N) half-saturation value insimulator)59
