Polyacrylamide PAM Flocculant for Water Treatment - Chemate

At present, the PAM water treatment is generally anionic type. That is, adding an appropriate amount of sodium hydroxide to hydrolyze, so that part of the amide group becomes carboxyl, and the degree of hydrolysis is proportional to the amount of sodium hydroxide added.

Using Polyacrylamide (PAM) to Reduce Erosion on Construction Sites

PAM is a term describing a wide variety of chemicals based on the acrylamide and acrylate units. When linked in long chains, these units can be modified to result in a net positive, neutral, or negative charge on the PAM molecule. The positively charged, or cationic, PAMs, are not used for erosion control because they can be toxic to fish and

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

On one hand, the particles with opposite charge can be thoroughly neutralized and destablized by the anionic chemical group. 11,12 On the other hand, these destabilized particles will be captured by the molecule chain of APAM to agglomerate and form large and compact flocs, and thus flocculation occurs. 13 During the solid-water separation process, the main mechanisms involved are charge
