One of the most prominent applications of polyacrylamide is in the water treatment industry. It acts as a flocculant, facilitating the aggregation of suspended particles in wastewater and drinking water treatment processes. By promoting the settling of solids and aiding in their removal, polyacrylamide helps enhance water clarity and quality. Additionally, it plays a crucial role in treating industrial effluents, where it assists in the removal of heavy metals and other contaminants.
