population balance modeling of precipitated calcium

Population balance modeling of precipitated calcium

Successful description of the precipitated calcium carbonate (PCC) flocculation kinetics by two cationic starches using population balance model is demonstrated in this paper. Population balance simulation provided an excellent agreement between the experimental data and the calculated values.

Population balance modeling of precipitated calcium

Population balance equation was employed to model the PCC flocculation process. • High charge density starch resulted in lower collision efficiency, lower restructure rate and stronger flocs. • The higher the temperature, the lower the energy dissipation rate • The addition of NaCl did not show effect on the collision efficiency for both

The computed results obtained using the population balance model are compared in Figs. 4 and 5 with experimental FSD at 20 ppm polymer concentration, measured after 10 and 30 min of flocculation, respectively. Although the model predicts broader FSD than the experimental data, it simulates the dynamic behavior of the process reasonably well.
