Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Biodegradation of Polyacrylamide and Its Derivatives | Environmental Processes

Although polyacrylamide (PAM) and its derivatives have many useful applications, their release in nature can have impacts on the environment and human health, thus bioremediation approaches for residual PAM are urgently needed. Biodegradation of PAM and its derivatives has been studied only in the last two decades, with most emphasis on acrylamide biodegradation. Microorganisms have been shown ...

Degradation of Polyacrylamide (PAM) and methane production by mesophilic and thermophilic anaerobic digestion: Effect of temperature ...

Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The impact or fate of PAM in AD under thermophilic conditions is still unclear.

Physiological Response of Daphnia magna to Linear Anionic Polyacrylamide: Ecological Implications for Receiving Waters - Water, Air, & Soil Pollution

It has been during the last decade that the linear (i.e., non-branched) anionic form of PAM (LA-PAM) has been tested and used (McLaughlin and Bartholomew 2007) as a potential technology for sealing unlined water delivery canals and ponds.
