What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is a polymer formed from acrylamide subunits, it is long-chain polymer designed to attract either positively charged particles (organic materials, such as carbon or human waste) or negatively charged particles (inert materials, such as sand or clay).

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.

Is polyacrylamide a water soluble polymer?

Polyacrylamide (PAM) is a water-soluble linear high-molecular polymer formed by the polymerization of acrylamide monomers initiated by free radicals. At the same time, it is also a kind of polymer water treatment flocculant.

Can polyacrylamide be used as a coagulant aid?

Reduce the amount of flocculant. Under the premise of achieving the same water quality, the use of polyacrylamide as a coagulant aid in combination with other flocculants can greatly reduce the amount of flocculant used. Improve water quality.

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

Can polyacrylamide flocculant improve water purification capacity?

Using organic polyacrylamide flocculant instead of inorganic flocculant, even don’t modify the sedimentation tank, it can increase water purification capacity by more than 20%. In sewage treatment, the use of PAM flocculant can increase the utilization rate of water recycling and can also be used for sludge dewatering.
