Brief Introduction: 

Anionic polyacrylamide (APAM) is a water-soluble polymer, mainly used for all kinds of industrial wastewater flocculation sedimentation, precipitation clarification treatment, such as steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other sewage treatment, sludge dehydration.
It can also be used for drinking water clarification and purification treatment.

There is a certain number of polar groups in APAM’s molecular chain, it can adsorb solid particles suspended in water to bridge between particles or condense particles to form large flocs through charge neutralization, so it can accelerate the sedimentation of particles in suspension, and has a very obvious effect of speeding up solution clarification and promoting filtration.

APAM(Anionic polyacrylamide) is a kind of flocculant, beside APAM, there are cationic polyacrylamide(CPAM), non-ionic polyacrylamide(NPAM).

Properties:

  • Appearance: white granule
  • Solid Content: 88% or higher
  • Molecular Weight: 3-20 million
  • PH: 1-14
  • Charge Density: 10-40(Mole%)
  • Degree of Hydrolysis: 10-35%
  • Dissolution Time: ≤60 min
  • Odor: Odorless
  • Thermal Stability: Easy to decompose when the temperature exceeded 120℃
  • Toxicity: Non-toxic
  • Corrosive: No corrosive

Applications In Industry:

  1. The coal washing plant chooses polyacrylamide for coal slurry precipitation concentration tail residue filtration, please choose anionic polyacrylamide(APAM), non-ionic polyacrylamide(NPAM), low cationic polyacrylamide(CPAM).
  2. Paint industry wastewater please choose anionic polyacrylamide(APAM), non-ionic polyacrylamide(NPAM). For paint wastewater treatment, the traditional method is to treat the mixed wastewater directly by coagulation, the treatment effect is not ideal, the effluent water quality is unstable, difficult to meet the discharge standard.
  3. Biological treatment of waste liquid of dairy industry, please choose cationic polyacrylamide (CPAM) for sludge treatment.
  4. Electroplating wastewater containing cyanide oxide treatment selection of anionic polyacrylamide (APAM), non-ionic polyacrylamide (NPAM), low cationic polyacrylamide (CPAM).
  5. Copper mining tailings wastewater treatment selection of anionic polyacrylamide(APAM), low cationic polyacrylamide(CPAM), non-ionic polyacrylamide(NPAM).

Package & Storage:

  • 25Kg plastic lining woven bag or paper plastic composite bag packaging, customized packaging is also acceptable.
  • When storing and transporting, pay attention to prevent heat and moisture to prevent package damage.
  • Dry powder products will absorb moisture and agglomerate when exposed for a long time. Stacking layers shall not exceed 20 layers.
