biodegradation of polyacrylamide and its derivatives manufacturer

some fungi and yeasts could degrade 60–80% of acrylamide. the biodegradation of pam and its derivatives are initiated by the enzyme amidase, either under aerobic or anaerobic conditions, and are further degraded partially or completely by an array of different enzymes.

factors influencing the efficiency of anionic polymer,proper mixing and dispersion of anionic polymer flocculant in the water are essential for its efficient performance in flocculation processes. the polymer must be evenly distributed throughout the water to ensure that all particles come into contact with the polymer and undergo flocculation.

How is polyacrylamide biodegradable?
Both single microbial species as well as mixed populations have been investigated for degradation. Biodegradation of polyacrylamide begins with amidase catalysed deamination of polyacrylamide to ammonia and polyacrylate. The liberated ammonia is then used as a nitrogen source for growth by the microbes.
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 fate of polyacrylamides in nature?
Polyacrylamides are widely applied for instance in wastewater treatment, papermaking, oil recovery and mining. Since they are bulk chemicals used in large quantities around the world, their fate in nature is of considerable interest. Both single microbial species as well as mixed populations have been investigated for degradation.
Can polyacrylamide be bioremediated?
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.
