best practices guidance for the use of anionic polyacrylamide
anionic vs. cationic pam polyacrylamide can be anionic (negatively charged) or cationic (positively charged). fish have a negative charge on their gill mucous. anionic pams are repelled by the negative charge on fish gills, while cationic pams are attracted to it. as a result, the cationic pam will attach to gills,
coagulation with polymers for nanofiltration pre-treatment of highly concentrated dyes: a review sciencedirect,aluminium-based coagulants with cationic polymers have been reported for the removal of dyes since 1970s [116]. in 1978, nakajima and kuwabara [117] patented a method to treat acid dyes using aluminium sulphate with cyanoguanidine-formaldehyde.

polyacrylamide pam flocculants water treatment industrial use,the hydrolyzed form of polyacrylamide (hpam), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic pam in oil and gas development as well as in soil conditioning. 1, 9,.
pam (anionic polyacrylamide) for industry chemical
pam, or anionic polyacrylamide, is a very long chain, high molecular weight organic polymer produced from natural gas, with characteristics which make it useful as a soil amendment to control runoff and soil loss.
application of polyacrylamide flocculants for water treatment on sale,likewise, polymers are used in wastewater treatment to improve the efficiency of sludge thickening and dewatering, and in drinking water treatment as flocculants to remove suspended solid [5] [10
polyelectrolyte polymers—types, forms, and function
the anionic polyacrylamide in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (phpa), although they are in actuality copolymers [80]. both high- and low-molecular-weight polymers are used as drilling fluid additives.

bio-based super absorbent polymers polyacrylamide chemical powder,contact lenses were the first application for super absorbents in the biomedical field. soft contact lenses were synthesized by polymerizing hydroxyethyl methacrylate in the 1950s which were further patented in 1960. for the continuous and controlled release of medication over a long period of time in the gut, super absorbents are being utilized.
solid–liquid separation of dairy barn by electrocoagulation with cationic polymer coagulant
high–molecular-weight polymer coagulants are widely used in wastewater treatment combined with traditional inorganic coagulants to improve the solid–liquid separation efficiency. however, it is desirable to keep chemicals used in treatments at minimum levels for economic and safety reasons. this study aimed to increase the efficiency of two-stage electro- and chemical-coagulation treatment
