Understanding the interaction mechanism between polymeric flocculants and solid particles in two oppositely charged solutions: bentonite and calcium fluoride, is of great practical and fundamental importance. Inorganic flocculants based on aluminum(III) or iron(III); cationic, anionic and non-ionic organic flocculants were used.The solution pH, which highly influenced the flocculation performance of the system, has been used as function of turbidity removal, sediment volume and velocity.
