Polyacrylamide is widely used in water treatment processes as a flocculant to remove suspended solids and clarify water. It helps in binding particles together, making them easier to filter out.

In the petroleum industry, it is employed in enhanced oil recovery to increase the viscosity of water, improving the efficiency of oil extraction from reservoirs.

In agriculture, it is applied to soil to reduce erosion, improve water retention, and enhance soil structure, promoting healthier crop growth.

It is also used in the production of paper and pulp to improve the strength and quality of the paper, as well as to aid in the retention of fine particles during the manufacturing process.

In the cosmetics industry, it serves as a thickening agent, stabilizer, and binder in various personal care products, such as lotions and creams.

Additionally, it is utilized in the medical field for gel electrophoresis, a technique used to separate proteins and nucleic acids based on their size and charge.
