What is polyacrylamide (PAM)?

Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.

Why is polyacrylamide used in water treatment?

With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.

Can polyacrylamide contribute to residual polymer formation?

Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.

What is hydrolyzed polyacrylamide (HPAM)?

Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.

What is a polyacrylamide & oligomer?

Polyacrylamide (PAM) & oligomers PAM is a water-soluble, odorless, white synthetic linear polymer with the repeating formula (-CH 2 CHCONH 2 -), and its monomer used is AM. Its molecular weight (MW) of PAM ranges from 10 5 to >10 7 Da, with a length of up to six million monomer units.

Can polyacrylamide improve hydrocarbon production efficiency?

npj Materials Sustainability 2, Article number: 15 (2024) Cite this article Polyacrylamide (PAM) and its derivatives play a pivotal role in various facets of hydrocarbon development. Proper application and treatment of PAM have the potential to enhance hydrocarbon production efficiency while mitigating adverse environmental effects.
