What is water soluble anionic polyacrylamide (PAM)?

Water soluble anionic polyacrylamide (PAM) was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1–10 g m −3 in furrow irrigation water. Water flowing from PAM treated irrigation furrows show large reductions in sediment, nutrients and pesticides.

What are the applications of polyacrylamide (PAM)?

As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields. Polyacrylamide is mainly used in the flocculation, sedimentation, and dewatering processes in municipal wastewater treatment.

Why is polyacrylamide important in wastewater treatment?

The correct use of polyacrylamide will contribute to improving municipal wastewater treatment results, protecting water resources, and achieving sustainable development. In the wastewater treatment industry, polyacrylamide has become an indispensable agent.

Can anionic polyacrylamide (PAM) be used to treat animal waste?

The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.

What is high molecular weight polyacrylamide (PAM)?

Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.

What is polyacrylamide used for?

Polyacrylamide (PAM) is a high molecular weight polymer that comes in three types: cationic, anionic, and non-ionic. Its molecular chain contains a large number of covalent bonds, giving it excellent adsorption properties. As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields.
