Many particles in water carry negative charges, which repel each other, preventing them from agglomerating. Cationic polymers, being positively charged, interact with these particles, reducing their repulsive forces. This interaction leads to the formation of larger aggregates or flocs, which are easier to remove from water.

In addition to charge neutralization, cationic flocculants promote bridging between particles. The long chains of the polymer can adsorb onto several particles simultaneously, effectively linking them together and facilitating the formation of dense flocs. This bridging mechanism enhances sedimentation or flotation, depending on the treatment process used. The result is a more efficient removal of turbidity and contaminants, leading to cleaner water. Overall, the cationic polymer flocculant's dual mechanism of charge neutralization and bridging makes it an essential component in modern water treatment systems.
