Blufloc Anionic Polyacrylamide, is solid powder water-soluble polymer with varying molecular weight and charge density. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solids.
Comparison of Anionic and Cationic Polyacrylamide: Which is …
The chemical principle of anionic polyacrylamide (APAM) in paper mill wastewater treatment is mainly based on the functions of electrical neutralization and adsorption bridging. Specifically, the polar groups on the APAM molecular chain can adsorb negatively charged suspended particles in water, and through electrical neutralization, bridge the particles to form larger flocs.
