Anionic Polyacrylamide (APAM) produced by Vanzon Water is a water-soluble polymer characterized by its high molecular weight and anionic charge
density. It is engineered to act as an exceptionally effective flocculant, binding suspended solids and colloidal particles in aqueous systems through
charge neutralization and bridge formation. APAM is widely recognized for its versatility, efficiency, and eco-friendly profile in industrial applications.
Key Functions & Mechanisms
Flocculation & Sedimentation
▲Neutralizes positively charged particles (e.g., clays, silts, metal oxides) to form dense, rapid-settling flocs.
▲Reduces turbidity and SS (Suspended Solids) by >90% in wastewater.
Filtration & Dewatering Aid
▲Improves sludge dewatering efficiency, reducing moisture content by 20–40%.
▲Enhances filtration rates in mineral processing and papermaking.
Viscosity Modification
▲Acts as a thickener in enhanced oil recovery (EOR) and drilling fluids.
Retention & Drainage Aid
▲Boosts fiber/filler retention in paper manufacturing, reducing material loss.

Primary Applications for polyacrylamide
Industry | Use Case | Benefit |
Water/Wastewater Treatment | Municipal & industrial sludge dewatering, potable water clarification | ISO certificated; lowers disposal costs |
Mining & Mineral Processing | Tailings dewatering, ore slurry sedimentation, coal washing | Recovers 99%+ water for reuse; minimizes environmental impact |
Paper & Pulp | Retention agent, white water clarification, coatig thickener | Improves paper strength, reduces BOD in effluent |
Oil & Gas indusry | Drilling fluid additive, EOR polymer flooding | Increases oil recovery by 15–30%; reduces friction loss |
Engineering slurry | Pile driving slurry, shield tunneling slurry treatment | The slurry settling speed has increased by 3 to 5 times. |
Adhesive industry | As an additive for glue | Good adhesion |
Instructions of polyacrylamide：
1.Before using, dissolve polyacrylamide with tap water at a ratio of 0.1%-0.5% and stir until fully dissolved.
2. Do not use iron materials to stir or hold PAM, because the reaction performance of PAM will decrease when it encounters iron.
3. The dosage needs to be calculated through laboratory pilot tests, with the aim of achieving the aggregation of flocs and presenting the phenomenon of sludge-water separation.
4.It is better to use up the prepared PAM solution within 24 hours.
5.Products should be stored in unopened package in a dry atmosphere at temperature no higher than 35℃.
