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.

Coagulation is another vital process in water treatment. This involves the addition of chemicals like alum (aluminum sulfate) or ferric chloride, which help to clump together (or coagulate) small particles and impurities in the water, making them easier to remove during the sedimentation process. This chemical reaction reduces turbidity and can significantly improve the clarity and quality of the water.
