This high-performance polymer is synthesized through a ternary copolymerization process of cationic monomers, acrylamide, and hydrolyzing agents, resulting in a unique molecular chain that contains both positive and negative charges.
Because of this dual-charge amphoteric structure, AmPAM can effectively treat wastewater systems where pH levels fluctuate, sludge composition varies, or both organic and inorganic contaminants are present. Compared with traditional anionic or cationic polyacrylamide, Amphoteric PAM offers greater adaptability, stronger flocculation, and improved sludge dewatering efficiency in demanding industrial environments.
How to Use Amphoteric PAM
To ensure optimal performance, follow these preparation steps.
1. Prepare Polymer Solution
Dissolve Amphoteric Polyacrylamide in clean water to create a 0.1%–0.2% aqueous solution.
2. Optimize Chemical Synergy
When used as a flocculant, AmPAM often reduces the total chemical dosage compared with using separate anionic or cationic polymers.
3. Conduct Jar Testing
For best results, perform a jar test to determine the ideal dosage and cationic/anionic balance for your wastewater conditions.
4. Storage Requirements
AmPAM is hygroscopic, so proper storage is essential: Store in a cool, dry, and ventilated warehouse, Protect from moisture, Keep packaging sealed tightly after opening,Shelf life: 24 months under proper storage conditions.
Main Applications of Amphoteric PAM
Industrial Sludge Dewatering
AmPAM is particularly effective for difficult sludge types, including:
- Municipal sewage sludge
- Oil refinery sludge
- Petrochemical wastewater sludge
- Chemical plant sludge
Its dual-charge structure helps capture both organic and inorganic particles, producing more stable flocs and improved filtration performance.
Construction & Civil Engineering
In construction projects, Amphoteric Polyacrylamide is used for:
- Construction slurry treatment
- Tunnel excavation wastewater
- Soil stabilization
- Mud and sediment clarification
This helps improve site water recycling and environmental compliance.
River Dredging & Port Sediment Treatment
AmPAM is widely used for river dredging and sediment management.
- Treatment of riverbed sediments (containing complex mixtures of organic matter, minerals, and silt)
- Large-scale dredging projects
This helps efficiently treat sediments and improves the environmental adaptability and operational efficiency of dredging works.
Paper & Pulp Industry
In the paper industry, Amphoteric Polyacrylamide functions as a multi-purpose additive, including:
- Retention aid
- Drainage aid
- Fiber recovery agent
This improves paper production efficiency and reduces raw material loss.

Why Choose Vanchor Amphoteric PAM
Dual-Charge Polymer Structure
AmPAM contains both positive and negative ionic groups, allowing it to capture a wider range of particles compared with single-charge polymers.
Excellent Performance in Variable Water Chemistry
Because of its amphoteric molecular chain, AmPAM performs well even when pH levels fluctuate or wastewater composition changes.
Superior Sludge Dewatering Efficiency
Specifically designed for difficult industrial sludge, AmPAM produces drier filter cakes and faster water release during sludge dewatering.
Reduced Surface Tension
Amphoteric Polyacrylamide significantly reduces surface tension, allowing faster floc formation and improved separation efficiency.
Rapid Dissolution
The polymer dissolves quickly in water within 60 minutes, ensuring smooth operation in industrial water treatment systems.
Customizable Polymer Formulation
We can adjust the cationic and anionic ratio of the polymer to meet the specific requirements of your sludge composition and wastewater chemistry.
