Why is polyacrylamide used in water treatment?

Polyacrylamide is ideal for water treatment because of its ability to increase viscosity and promote flocculation of particles. Flocculation is a process where suspended particles precipitate in a fluid to form a clump or floc. It is an essential process in water treatment.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a type flocculant of polymer that is soluble in water, and it is formed through acrylamide polymerization. It can be adjusted for use in a wide range of applications. This type of polymer is produced and sold in different forms, which include cationic polyacrylamide, anionic polyacrylamide, and non-anionic.

Which polyacrylamide is best for water purification?

PAM has good coagulation qualities that make it the best for water purification. Coagulation is all about changing a liquid to a solid or half-solid state by adding a specific chemical or coagulant. Polyacrylamide products also combine with water to produce insoluble hydroxides.

How do I choose the right polyacrylamide?

Colloid concentration in water and the number of suspended particles can help you settle for the right polyacrylamide. A colloid is any element made up of particles that are considerably larger than atoms and molecules but less visible to the human eye. You can settle for the inorganic PAM if for fast flocculation.

Which ionic polyacrylamide is best for sewage treatment?

Anionic polyacrylamide can be categorized into strong, medium, and weak. This is according to their hydrolysis reaction. Cationic polyacrylamide is widely used for municipal sewage treatment. Its sludge dewatering qualities make it the best for sewage treatment. Cationic polyacrylamide flocculant is grouped depending on its levels of ionicity.

What is polyacrylamide used for?

Polyacrylamide is also a perfect stabilizer and binder. This makes it best for the production of lotions. The paper industry also benefits significantly from this type of polymer because of its ability to bind pulp fibers. More applications include soil conditioning, manufacturing of textiles, food additive, processing ores, and mining.
