Abstract
Experimental conditions required for the formation of pelleted flocs from suspensions of polystyrene latex particles using cationic polymers are examined. It is found that the formation of pelleted flocs depends on the polymer and particle concentrations, the polymer molecular weight and charge density, and the intensity of mixing, and that pelleted flocs are formed only in the limited region where these factors are present, otherwise either microflocs or bulky flocs are formed. It is presumed that the bare surface of the particles and the free cations of the adsorbed polymers on the particle surface which are not consumed by adsorption play an important role in pelletization. The critical volume fraction of particles ø pt above which pelleted flocs are formed using macroscopically neutralized particles is found to be estimated by the following correlation: ø pt ≈4 × 10 −5 C pN A pN 0M where C p is the polymer concentration, N A the Avogadro constant, N 0 the initial particle concentration, p the charge density of the polymer, and M the molecular weight of the polymer.
