Polyacrylamide - Wikipedia

[1] Physicochemical properties Polyacrylamide is a polyolefin. It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone.

Sep 7, 2018 · High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and...

May 18, 2018 · Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

Polyacrylamide. Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the capture of dispersed bacterial cells, suspended solids, and cell fragments

The effect of electric charge density of polyacrylamide (PAM

Definition Polyacrylamides (PAMs), are polymer-based materials used to facilitate erosion control and decrease soil sealing by binding soil particles, especially clays, to hold them on site. In addition, these types of materials may also be used as a water treatment additive to remove suspended particles from runoff. Description and Purpose

Best Practices Guidance for the Use of Anionic Polyacrylamide

Anionic vs. Cationic PAM ?Polyacrylamides 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,
