Polyacrylamide (PAM) is a high molecular polymer, which has good solubility in water, and good flocculability. It can reduce the friction between fluids. According to the ion properties, polyacrylamide could be characterized as 4 types—anionic PAM (APAM), cationic PAM (CPAM), nonionic PAM (NPAM), and amphoteric PAM (ACPAM).

By varying the concen...
Cationic polyacrylamide CPAM. Cationic polymeric flocculant is a kind of linear macromolecular compounds dissolve in water, the molecular weight between 600-12 million, cationic PAM in acidic or alkaline medium is electropositive, such can effectively suspended particles in the sewage wastewater with negatively charged for flocculation
Anionic Polyacrylamide PAM for India for waste water treatment
Cationic polyacrylamide(PAM) for water treatment. Cationic polyacrylamide(PAM) is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water . Polyacrylamide degradation and its implications in. Sep 07, 2025· High molecular weight (10 6 –3 × 10 7 Da
High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction
Water-soluble polymers anionic polyacrylamide for Lebanon
Anionic/Cationic PAM|Polyacrylamide Polymer. CPAM Cationic polyacrylamide Introduction: Cationic polymer flocculant is a water soluble linear polymer, and its molecular weight is between 400-1200million. CPAM also can be dissolved in methanol and ethanol, but can not be dissolved in ketene, esters, hydrocarbons and other organic solvents.
This study shows the benefits of using high molecular weight cationic polyacrylamide (PAM) in the purification of wastewater discharged from a wet scrubber in secondary lead smelter for reuse. The effect of temperature, pH, filtration pressure, polymer dose and different types of filtration fabrics on filtration rate (¦x), efficiency (¦ε) and quality of the produced water for
Synthesis of block cationic polyacrylamide precursors
Synthesis of cationic polyacrylamides (CPAMs) by introducing cationic polymer precursors followed by chain extension of acrylamide (AM) homopolymer blocks via RAFT polymerization is a promising approach for engineering high-performance CPAMs. However, the aqueous solution polymerization of AM usually leads to high viscosity, thus limiting the solid content in the polymerization system.
Cationic polyacrylamide (CPAM) is a type of polyelectrolyte that has been widely used as a sludge conditioner because of its low dosage requirement, high efficiency, and pollution-free effects. Previous studies report that CPAM dosage is critical in sludge conditioning because overdoses increase cost and deteriorate sludge dewaterability [12] .
Cationic polyacrylamide copolymers (PAMs): environmental
Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil. Dieter Hennecke 1Fraunhofer Institute for Molecular Biology and Applied Ecology, Auf dem Aberg 1, 57392 Schmallenberg, Germany.
The influence of cationic and anionic polyacrylamides (PAM) on the floc size, compressive yield stress, and rheological behaviour of kaolinite suspensions has been investigated at pH 7. At optimum polymer concentrations, the kaolinite floc sizes were larger in the presence of anionic PAM than cationic PAM.
