In drinking water treatment, cationic polymers are often used in combination with coagulants, such as aluminum and iron salts, to enhance the removal of turbidity and microorganisms. These polymers improve the efficiency of the coagulation-flocculation process, leading to clearer water with reduced pathogen levels. Moreover, the use of cationic polymers can also reduce the amount of chemical coagulants required, which is beneficial for both environmental and economic reasons.

The effectiveness of polyacrylamide as a flocculant lies in its ability to enhance the aggregation of fine particles. When added to a suspension, PAM molecules adsorb onto particle surfaces and form bridge connections between individual particles. This bridging action leads to the formation of larger aggregates or flocs, which can then settle more quickly under the influence of gravity. This mechanism not only improves sedimentation rates but also aids in the removal of suspended solids, colloids, and impurities.
