Growth dilution rate

Growth dilution can be treated similarly to elimination, as it results in decreasing concentrations in the modelling. Growth dilution rate constant \(k_{g}\) has therefore a similar unit to the elimination rate (\(day^{-1}\)).

Growth dilution



Elimination of a single form of the NM:

\(C_{org} = C_{env} + k_{1}\ast SF\ast t+C_{env}\ast \frac{k_1}{k_2+k_g} \ast (1 - e^{-(k_{2}+kg)\ast t}) \ast (1-SF)\)
