Polyacrylamide is widely used in water treatment processes as a flocculant to remove suspended particles and clarify water. It helps in binding fine particles together, making them easier to separate and filter. 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 reservoirs. In agriculture, it is applied to soil to reduce erosion, improve water retention, and enhance soil structure. Additionally, it is utilized in the production of paper and textiles to improve strength and quality. Its gel form is also used in electrophoresis for separating proteins and nucleic acids in biochemical research.
