Two different approaches for a two dimensional population balance modeling strategy are used and compared in this work to describe the flocculation of PCC particles induced by polyelectrolytes, the fixed pivot technique model and the model proposed by Hounslow (1988) and Spicer and Pratsinis (1996b). The median size diameter of the flocs, obtained...
