Polyacrylamide (PAM) is a water-soluble synthetic linear polymer synthesized from acrylamide monomers. By modifying the ionic charge, it can be customized as Anionic (APAM), Cationic (CPAM), or Nonionic (NPAM). The molecular weight plays a critical role in flocculation performance:
The global commercial sector is transitioning toward high-concentration, dust-free granules and automated preparation systems. Wuxi BS's continuous production line ensures batch-to-batch consistency by controlling raw material variables such as the quality of the Acrylonitrile feed. Our supply chains are structured to minimize costs and shield international buyers from regional raw material price spikes.

Cationic charge density selection depends on the organic content and zeta potential of the wastewater sludge. Highly organic sludges (e.g., municipal primary and activated sludge) require medium-to-high charge densities (40% to 80% charge) to achieve neutralization. For inorganic sludges with low organic fractions, lower charge densities (10% to 30%) are recommended. Standard jar testing is recommended to find the dosage point before overdosing causes colloidal restabilization.
Fish-eyes form when dry polymer powder rapidly hydrates on the surface, creating a gel coat that prevents water from reaching the dry center. To prevent this, add the powder slowly into a vortex created by a mechanical stirrer (operating at 100-300 RPM). Ensure dilution water is between 15°C to 40°C. Maintain agitation for 40 to 60 minutes until the granules are dissolved. Avoid high-shear pumps (e.g., gear pumps) for transfer, as high shear can break the polymer chains, reducing flocculation effectiveness.
In mining applications, high molecular weight polymers (APAM, 18-22M Daltons) are used to bridge suspended mineral particles. The long polymer chains capture multiple fine particles to form large flocs. Larger flocs settle faster, in accordance with Stokes' Law. However, if the molecular weight is too high for the pumping system, the shear forces in the pipes can degrade the polymer chains, reducing its efficacy.
Our dry polyacrylamide powder has a shelf life of 24 months when stored in original unopened bags in a cool, dry place away from direct sunlight, humidity, and temperatures exceeding 40°C. Liquid formulations or prepared solutions (0.1%-0.5% concentration) degrade more quickly: anionic solutions should be used within 7 to 10 days, while cationic solutions should be used within 24 to 48 hours to prevent hydrolysis-induced loss of activity.
For potable water and sensitive industrial applications, we utilize advanced post-polymerization treatments to convert residual monomer molecules. Liquid chromatography testing is conducted on every batch to confirm that the residual acrylamide monomer level is kept below 250 ppm (0.025%), satisfying international health and safety regulations for drinking water treatment chemicals.
