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 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
Unveiling the mechanisms of how cationic polyacrylamide
The cationic PAM used in this study was purchased from Chongqing Reagent Company, which had a molecular weight of 6–8 million Da with a 30% charge density, and with a residual acrylamide content less than 10 mg/kg. Bovine serum albumin (BSA) was used as the model protein compound with average molecular weight 67000 (Sigma-Aldrich).

A population balance model for flocculation of colloidal
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.
