polyacrylamide pam flocculants water treatment industrial use

this review examines the chemical, mechanical, thermal, photolytic, and biological degrada-tion of pam under a broad range of environmental conditions. we then consider available options for.

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.

recent achievements in polymer bio-based flocculants for low cost

polymer flocculants are used to promote solid–liquid separation processes in potable water and wastewater treatment. recently, bio-based flocculants have received a lot of attention due to their superior advantages over conventional synthetic polymers or inorganic agents.

advances of polyacrylamide flocculants in mining industry,polyacrylamide plays an important role in mining industry and is widely used in tail water treatment and mineral flocculation. in this paper, the types, synthesis methods, flocculation mechanism and related applications of these flocculants were reviewed.

spotlight on the life cycle of acrylamide-based polymers

although the general trend is highly biodegradable polymers, the authors must point out that such polymers would be less effective in the agricultural field, where the polymers must be stable enough to swell and release water over long periods of time.

polyacrylamide soil conditioners: the impact on- manufacturer.this paper aims to review polyacrylamide structure, synthesis methods, and their adsorption on the surface of clay minerals. the literature studies on the impacts of pam adsorption on clay particles’ aggregation and heavy metal ions’ accumulation in soil environments have been also presented.

current status on the biodegradability of acrylic polymers

high concentrations of the inhibitor resulted in a significant decrease of toc removal rate and the non-reduction of polymer mw, suggesting that cytp450 participates in the c-c backbone cleavage and carbon biotransformation.
