degradation of polyacrylamide and its significance in nature

high quality flocculant polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, a soil conditioner, and a viscosity improver and friction enhancer.

recent achievements in polymer bio-based flocculants for sale,among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (pam)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process. the acrylamide monomer can be used for grafting or crosslinking of other type of polymers.

transfer and degradation of polyacrylamide-based flocculants

the aim of this review was to summarize information and scientific data from the literature dedicated to the fate of polyacrylamide (pam)-based flocculants in hydrosystems. flocculants, usually composed of pam, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. these polymers can contain

optimizing the flocculation effect of cationic polyacrylamide,cationic polyacrylamide (cpam) is a commonly used flocculant for water treatment. factors that affect the flocculation effect and can be controlled manually include the type and dosage of cpam, wastewater ph, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of cpam. in this paper, the optimal flocculation conditions of a novel cpam were

Why is Pam a high molecular weight polymer?
PAM was the only high molecular weight polymer in the wastewater. These molecular chains inevitably coiled and became entangled, which increased the viscosity of the wastewater. The changes in viscosity ( Table 1) show that most of the macromolecular chains were effectively interrupted especially in R1 [ 2, 19 ].
Does biological filtration improve polyacrylamide biodegradation?
Freedman, D. E. et al. Biologically active filtration for fracturing flowback and produced water treatment. J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
What is the molecular weight of Pam?
The molecular weight (MW) of commercial PAM ranges from 10 5 to 10 7 Da. High molecular weight PAM (10 6 Da) have a wider range of applications due to their high viscosity, drag reduction capabilities, and water retention properties. PAMs are widely used in environmental systems.
Can a multistage biofilm reactor treat Pam production wastewater?
In this study, a multistage biofilm reactor was able to treat PAM production wastewater. The independent chambers formed a unique bacterial community that could improve the reactor performance and tolerate the substrate shock loads.
