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.

What is cationic polyacrylamide flocculant?

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. The ionicity levels include strong, medium, and weak.

When did polyacrylamide become a drinking water treatment chemical?

Polyacrylamide, acrylic acid polymers and copolymers were endorsed by the NHMRC as drinking water treatment chemicals in 1977 and 1979. The revision undertaken in 2003 did not result in any change to the status of this chemical for the treatment of drinking water.

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.

How is partially hydrolyzed polyacrylamide wastewater treated?
