Heterodisperse describes a particle system with a broad size distribution, in contrast to monodisperse. Such systems exhibit complex filtration behaviour because fines fill the voids between coarse particles, reducing cake porosity and increasing pressure drop. At the same time, the coarse fraction forms a permeable skeleton that may stabilise clarity once the cake is established. Understanding heterodispersity is essential for feed conditioning and media selection: narrow cuts of flocculant addition or classification upstream can transform an unstable heterodisperse feed into a predictable, easily dewatered cake. Analytical PSD data (D10/D50/D90) and rheology curves help engineers optimise for balanced flux and clarity.
