sequently, pilot studies should always be run on wastes containing ammonia-N concentrations substantially higher than those found in domestic wastewater. A final circumstance in which a curve of a different shape may be obtained is when the wastewater contains chemicals inhibitory to the autotrophic bacteria. Such a curve is shown in Figure b.b." Inhibitory compounds can reduce |iA and increase i\.\f|, both of which reduce the percent nitrification achieved at a given SRT, making the curve
