Abstract
A mathematical model is proposed to assess the dynamics of stable nitrogen isotopes 14N and 15N in nitrification process—transformation of ammonium into nitrites and nitrates. The model was calibrated against experimental data with nitrite as an end nitrification product. The model, which use the Monod dependence, provides a description of the nonlinear dynamics of functioning and enables improving the kinetic coefficient of nitrification process.
