Polyacrylamide is widely used in water treatment processes as a flocculant to remove suspended solids and clarify water. It helps in aggregating fine particles into larger clumps, making them easier to filter out. In the oil and gas industry, it is employed in enhanced oil recovery to increase the viscosity of water injected into reservoirs, improving the extraction of crude oil. In agriculture, it is applied to soil to reduce erosion, improve water retention, and enhance soil structure. Additionally, it is utilized in the paper and pulp industry as a retention and drainage aid, improving the efficiency of paper production. Its ability to form gels also makes it useful in biomedical applications, such as drug delivery systems and electrophoresis for DNA and protein separation.
