Polyelectrolytes are water-soluble polymers that contain charged groups along their molecular chains, making them highly effective for various industrial and environmental uses. These compounds are often utilized in water treatment processes as coagulants and flocculants, aiding in the removal of suspended solids, organic matter, and other impurities. Their capacity to promote the aggregation of fine particles ensures cleaner and safer water, which is crucial in industries such as wastewater treatment, paper manufacturing, and oil recovery.

                              There are three types of polyelectrolytes: anionic, cationic, and nonionic, each designed for specific purposes depending on the type of contaminants and process needs. Beyond water purification, they are also used in agriculture, food processing, and pharmaceuticals due to their versatile characteristics. As environmental concerns grow, the demand for effective and sustainable water treatment solutions has increased the importance of polyelectrolytes in contemporary industrial practices.
