Polyacrylamide is widely used in water treatment processes to remove suspended solids and clarify water. It acts as a flocculant, helping particles to clump together and settle out of the water. In the petroleum industry, it is employed in enhanced oil recovery to improve the efficiency of oil extraction by increasing the viscosity of water injected into oil wells. In agriculture, it is used as a soil conditioner to reduce erosion and improve water retention in the soil. Additionally, it finds applications in the paper and textile industries as a retention aid and sizing agent, improving the quality and strength of the final products.
