Polyacrylamide

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]

Polyacrylamide in Agriculture and Environmental Land Management

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation©induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms

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.

Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe | Full Text

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C

degradation of polyacrylamide (pam) and methane production by mesophilic and thermophilic anaerobic digestion: effect of temperature

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. This study mainly focuses on PAM degradation and enhanced methane production

Polyacrylamide preparations for protection of water quality threatened by agricultural runoff contaminants

In the 1990s, water soluble anionic PAM was found to be a highly effective erosion-preventing and infiltration-enhancing polymer, when applied at rates of 1¨C10 g m ?3) in furrow irrigation water (Lentz et al., 1992, Lentz and Sojka, 1994, McCuthan et al., 1994, Trout et al., 1995, Sojka and Lentz, 1997, Sojka et al., 1998a, Sojka et al., 1998c).
