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.
