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

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.

effects of polyacrylamide molecular weight and mass concentration on water transport characteristics of iron tailings

Effects of polyacrylamide molecular weight and mass concentration on water transport characteristics of iron tailings

Polyacrylamide (PAM) can regulate soil water, but it is rarely used when remediating tailings matrix. In this research, PAM of four molecular weights of 300w, 600w, 800w, and 1000w were selected ...

isolation and characterization of polyacrylamide-degrading bacteria from dewatered sludge - pmc - national center for biotechnology information

Isolation and Characterization of Polyacrylamide-Degrading Bacteria from Dewatered Sludge - PMC - National Center for Biotechnology Information

Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge.

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.

Polymers | Free Full-Text | Exploring Alternatives to Polyacrylamide: A Comparative Study of Novel Polymers in the Flocculation

Although the main concern of PAM usage is water retention, the following disadvantages should also be addressed: (1) high molecular weight PAM flocculants are difficult to disperse in tailings with high solid content []; (2) PAM degrades slowly in water, which negatively impacts the environment [14,15]; (3) to enhance the particle-PAM bonding and improve separation efficiency, divalent cations ...
