5. Compartmental model Stepwise determination
Longitudinal compartmentalization
Vertical compartmentalization
Flux calculations

6. Final compartmental network
TIS model CM
CFD model

7. conclusions
CFD-Biokinetic model: detailed knowledge of the process variables (i.e. concentrations)
CM based on both hydrodynamics and CFD-biokinetics
A Dynamic CM will reduce calibration efforts and uncertainties
