A simple model to study the flocculation of suspensions over time

The model based on logistic growth theory, that was introduced in Chassagne, Claire, and Zeinab Safar. “Modelling flocculation: Towards an integration large-scale sediment transport models.” Marine Geology 430 (2020): 106361, can be used to the time evolution of either particle (floc) size or concentration particles a given size. In present article, we show how this easily linked many studies performed over years about flocculation kinetics at onset experiments. Flocculation experiments done kaolinite suspensions destabilized by addition salt are as examples. Both perikinetic orthokinetic considered. By fitting experimental data whole experiment period, it is shown floc L(t) follows relation dL/dt = L/tb − L2/(Leqtb) where tb characteristic Leq size, which obtained from fits.
