Polyacrylamide, commonly known as PAM, is one of the most widely used performance polymers across water treatment, oil & gas, mining, agriculture, and industrial processes.
Its ability to boost clarity, improve separation, and optimize process efficiency has made it a cornerstone chemical for thousands of facilities worldwide.
In this guide, we break down everything you need to know: what polyacrylamide is, how it works, key benefits, safety considerations, major industry applications, insights into biodegradability, and pricing factors.
What Is Polyacrylamide? Understanding Its Uses and Benefits
Polyacrylamide (PAM) is a water-soluble polymer formed from acrylamide subunits. Depending on its manufacturing, it can be anionic, cationic, nonionic, or amphoteric, making it adaptable to a wide range of operational needs.
Primary Functions
- Flocculation
- Coagulation
- Thickening
- Dewatering
- Viscosity modification
- Enhanced oil recovery
Due to these performance characteristics, polyacrylamide is considered one of the most efficient and cost-effective treatment chemicals globally.ncy, making high-MW polymers essential for maximizing reservoir contact.
How Does Polyacrylamide Work in Water Treatment?
In wastewater treatment, drinking water purification, and industrial effluent treatment, PAM acts as a flocculant or coagulant aid.
How PAM Works?
- Charge Neutralization: The polymer attracts suspended solids, neutralizing their surface charge.
- Particle Bridging: Long polymer chains bind fine particles together.
- Floc Formation: These aggregated particles form large, heavy flocs.
- Rapid Separation: Flocs settle, float, or filter out, dramatically improving clarity.
Results Expected
- Faster sedimentation
- Higher water clarity
- Lower sludge generation
- Improved dewatering efficiency
- Reduced chemical consumption
This is why polyacrylamide remains the gold standard flocculant worldwide for wastewater treatment.
What Are the Key Benefits of Polyacrylamide in Industrial Applications?
Whether used as a flocculant, thickener, binder, or drag reducer, PAM delivers unmatched performance.
- Exceptional Flocculation Efficiency: Removes suspended solids, organic matter, and colloids with minimal dosage.
- Lower Overall Operating Cost: Reduces sludge, energy use, and demand for secondary chemicals.
- Versatile Across pH & Temperature Conditions: Performs consistently in extreme industrial environments.
- Highly Customizable: Available in powder, emulsion, bead, and liquid forms for tailored performance.
- Increases Throughput & Productivity: Improves clarity, boosts separation, and stabilizes processes in mining,
dewatering, and EOR.
Is Polyacrylamide Non-Toxic and Safe for Use?
Yes. Properly polymerized polyacrylamide is considered non-toxic and safe for regulated industrial use.
Important Distinction
- Acrylamide monomer = toxic
- Polyacrylamide polymer = safe, stable, and non-toxic
Safety Highlights
- Non-hazardous under normal handling
- Stable and non-reactive
- Widely approved for water treatment
- Safe for indirect food-contact applications
What Is Polyacrylamide Used For in Other Industries?

Is Polyacrylamide Biodegradable?
Polyacrylamide is not considered biodegradable in the traditional sense, but it does gradually break down through:
- UV exposure
- Thermal degradation
- Mechanical shear
- Hydrolysis over time
It is environmentally stable, non-volatile, and non-bioaccumulative, making it safe for long-term industrial use.
What Affects Polyacrylamide’s Price?
The price of polyacrylamide varies depending on formulation, conditions, and required performance.
Key Factors That Influence Price
- Type of PAM (Anionic, Cationic, Nonionic, Amphoteric)
- Production method (including UV-RAFT or controlled polymerization)
- Molecular Weight / Charge Density
- Form (Powder, emulsion, granular, liquid)
- Order quantity (MOQ)
- Packaging
- Logistics and international shipping rates
Conclusion
Polyacrylamide is one of the most effective, versatile, and reliable industrial polymers available today.
Whether used for water treatment, oil and gas field operations, mining, or agriculture, PAM delivers powerful performance through exceptional flocculation, dewatering, and process-efficiency benefits.
With the right grade, optimized for molecular weight, charge density, and application, industries can achieve cleaner water, reduced waste, lower operating costs, and improved system performance.
