Cationic polyelectrolytes (C-PE) are utilized as flocculants to enhance the rate of solid/liquid separation in water treatment. In the water bodies, there are inevitable natural organic matter (NOM), which is oppositely charged in addition to solid particles. Previously, we have reported the remarkable effect of negatively charged polyacrylic acid (PAA), an analogue of NOM to inhibit the function of C-PE in flocculation1 . However, in reality, an effect of charge density of C-PE can be considered to have large influence on this behavior. In the presence study, we utilized polystyrene latex (PSL) as colloidal particle, a model humic acid and two different charge density of C-PE.
