Anionic Polyacrylamide (PAM) is a water-soluble polymer with negatively charged functional groups. It is one of the most widely used flocculants in water treatment, wastewater management, and industrial applications worldwide.Our anionic PAM offers superior flocculation efficiency, rapid settling, and excellent clarification performance while maintaining cost-effectiveness in large-scale treatment operations.
Description

Tairan Chemical’s Anionic Polyacrylamide (APAM) is a high molecular weight, water-soluble polymer designed for solid-liquid separation. With its high negative charge density, it effectively neutralizes positive charges on suspended particles, bridging them into large, rapidly settling flocs.
As a leading source manufacturer, our APAM is engineered for cost-efficiency, requiring lower dosage while delivering superior clarity. It is widely used in industrial wastewater treatment, municipal sewage sludge dewatering, mining tailings, and the paper industry.
● Rapid Flocculation: Forms large, dense flocs quickly, significantly speeding up sedimentation rates.
● High Molecular Weight: Available from 8 million to 25 million Daltons to suit various shear conditions.
● Cost-Effective: Effective at low dosages (typically 0.1 - 10 ppm), reducing overall treatment costs.
● Versatile Solubility: Dissolves completely in water without forming insoluble "fish eyes."
● Eco-Friendly: Non-corrosive and compliant with major environmental standards for industrial discharge.

1. Industrial Wastewater TreatmentSpecifically effective for wastewater with neutral to alkaline pH and high concentrations of suspended positively charged particles. Ideal for:
● Steel & Metal Plating Plants
● Coal Washing & Sand Washing
● Electroplating Effluent
2. Mining & Mineral ProcessingUsed as a powerful settling agent in tailings dewatering and mineral recovery (Gold, Copper, Iron, Zinc). It recovers water for reuse and creates dry, stackable tailings.
3. Oil & Gas IndustryUtilized in Enhanced Oil Recovery (EOR) to improve oil sweep efficiency. Also serves as a drilling fluid additive to reduce friction and stabilize boreholes.
4. Paper Making IndustryActs as a retention aid and dry strength agent, improving fiber retention and paper quality while reducing raw material loss.
● Packaging: 25kg Kraft paper bag with inner PE liner, or 750kg Big Bag (Super Sack).
● Storage: Store in a cool, dry, and well-ventilated place. Keep away from moisture and direct sunlight.
● Shelf Life: 24 months when stored correctly.
Q: What is the difference between Anionic and Cationic Polyacrylamide?A: Anionic PAM carries a negative charge and is best for treating inorganic suspensions (like sand, clay, minerals) with a neutral to alkaline pH. Cationic PAM carries a positive charge and is suited for organic sludge (sewage, food processing) with acidic to neutral pH.
Q: Can I get a free sample for testing?A: Yes! As a factory, Tairan Chemical provides free samples (usually 500g) for you to run "Jar Tests" in your lab to determine the best molecular weight for your water. [Contact us now].
Q: How do you ensure product quality?A: We are ISO 9001:2015 certified. Every batch undergoes strict quality control for molecular weight, hydrolysis degree, and solubility before shipment.
