Polyacrylamide is widely used in water treatment processes as a flocculant to help remove suspended particles and clarify water. It is also employed in the oil and gas industry to enhance oil recovery by improving the viscosity of water injected into reservoirs. In agriculture, it is applied to soil to reduce erosion and improve water retention, promoting better crop growth. Additionally, it serves as a thickener and binder in various industries, including cosmetics, paper manufacturing, and mining, where it aids in sedimentation and filtration processes.
