Once an API is developed, it must undergo rigorous testing and validation to ensure its safety and effectiveness. This includes preclinical studies and multiple phases of clinical trials. Regulatory bodies such as the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) closely monitor these processes to safeguard public health. Only when a drug passes through these stringent evaluations can it reach the market.

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.
