Polymers can be cationic, anionic or nonionic. Coagulant and Flocculant. Filed Under: Chemistry Tagged With: Cationic coagulants, Coagulant, coagulation, Colloidal solution, flocculant, flocculation. Coagulation is achieved by neutralizing the particles and thus, the repelling force between the particles is greatly reduced. The particles are distributed within the colloidal medium, and do not settle down if it is left still. Flocculation can occur through the use of a coagulant, flocculant or both. Coagulants can be metallic salts (e.g. Such particles are characteristically very small and the suspended stability of such particles (colloidal complex) is due to both their small size and to the electrical charge between particles. Coagulants and Flocculants perform an important function in the operation of sediment basins. 1. Assessment of the alternative flocculant/coagulant will focus on all site specific environmental risks associated with treating and discharging water. According to the IUPAC definition, flocculation is "a process of contact and adhesion whereby the particles of a dispersion form larger-size clusters". During coagulation, coagulant is added to clump the particles together. Pool Clarifier vs. Flocculant. Flocculants try to bridge the molecules forming clumps.
