Does polyacrylamide thicken?

Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed. When presenting a semi-network structure, thickening becomes more apparent.

What is organic polymer flocculant cationic polyacrylamide (CPAM)?

The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [11, 12, 13, 14, 15].

Can cationic polyacrylamide be used in oilfield wastewater treatment?

Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.

Can cationic polyacrylamide flocculants be used to treat oily water?

Shu, G., Bu, K., Zhao, B. & Zheng, S. Evaluation of newly developed reverse demulsifiers and cationic polyacrylamide flocculants for efficient treatment of oily produced water. Colloids Surf. A 610, 125646 (2021). This work was supported by grants from the “Qihang Program” of the Southwest Petroleum University (2023QHZ001) awarded to C.Z.

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.

Which cationic polyacrylamide polymer has the highest recovery factor?

Fluorescent cationic polyacrylamide polymers at a concentration of 2000 ppm were employed, and the polymer flow was observed using a UV lamp through a glass 1/4 five-spot model. The results, as shown in Figure 9, indicate that Poly 400 achieved the highest recovery factor.
