PAM (Polyacrylamide) – Water Treatment Flocculant Supplier from China
PAM (Polyacrylamide) is a high-performance water-soluble polymer widely used as a flocculant, coagulant aid, and sludge conditioning agent in wastewater treatment, mining, oilfield, paper manufacturing, and various industrial processes.
Polyacrylamide works by promoting the aggregation of fine suspended particles into larger flocs, making solid-liquid separation more efficient. Due to its excellent flocculation performance, PAM is one of the most widely used polymer chemicals in water and wastewater treatment applications.
We supply Polyacrylamide (PAM) from China in different ionic types, including Anionic PAM, Cationic PAM, and Nonionic PAM, for international customers, water treatment companies, distributors, and industrial users.
Product specifications including COA, SDS, TDS, ionic degree, molecular weight, and viscosity data can be provided according to customer requirements.

Polyacrylamide is a synthetic polymer formed from acrylamide monomers. Depending on the modification of its molecular structure, PAM can provide different electrical charges and performance characteristics.
What Is Polyacrylamide (PAM)?
Polyacrylamide is a linear polymer with high molecular weight and excellent water absorption properties.
In water treatment applications, PAM acts mainly through bridging flocculation. The polymer chains attach to suspended particles and connect multiple particles together, forming larger flocs that can be separated more easily.
PAM does not directly disinfect water or remove dissolved contaminants. Its primary role is improving the separation efficiency of suspended solids.
Types of Polyacrylamide (PAM)
Commercial PAM is mainly classified according to ionic characteristics.
Anionic Polyacrylamide (APAM)
Anionic PAM is the most commonly used type in industrial wastewater treatment.
It is widely applied in:
- Municipal wastewater treatment
- Industrial wastewater treatment
- Mining wastewater
- Coal washing
- Mineral processing
- Sludge dewatering
Anionic PAM is especially suitable for systems containing inorganic suspended particles and positively charged mineral particles.
Cationic Polyacrylamide (CPAM)
Cationic PAM is mainly used for sludge treatment and dewatering applications.
Common applications include:
- Municipal sludge dewatering
- Industrial sludge treatment
- Paper mill wastewater
- Organic wastewater treatment
The positive charge of cationic PAM helps interact with negatively charged organic particles and sludge particles.
Nonionic Polyacrylamide (NPAM)
Nonionic PAM has relatively low ionic charge and is used in applications where charge interaction needs to be minimized.
Applications may include:
- Acidic wastewater treatment
- Mineral processing
- Specialty industrial applications
The correct PAM type depends on wastewater characteristics, suspended solids, pH, and treatment objectives.
PAM for Wastewater Treatment
Wastewater treatment is one of the largest applications of Polyacrylamide.
PAM is used as a flocculant to improve:
- Suspended solids removal
- Sludge settling
- Solid-liquid separation
- Filtration efficiency
- Sludge dewatering performance
Applications include:
- Municipal wastewater plants
- Industrial wastewater facilities
- Chemical plants
- Food processing wastewater
- Textile wastewater
- Paper mill wastewater
The selection of PAM depends on the wastewater composition and treatment process.
PAM for Sludge Dewatering
PAM plays an important role in sludge dewatering processes.
During sludge treatment, PAM helps aggregate small sludge particles into larger flocs, improving:
- Water release from sludge
- Filter press performance
- Centrifuge efficiency
- Sludge handling
Cationic PAM is commonly selected for sludge dewatering because of its interaction with organic sludge particles.
PAM for Mining Industry
Polyacrylamide is widely used in mining and mineral processing.
Applications include:
- Mineral separation
- Tailings treatment
- Coal washing wastewater
- Ore processing
- Tailings settling
PAM helps accelerate sedimentation and improve the recovery of water from mining wastewater systems.
PAM for Oilfield Applications
PAM can also be used in oilfield chemical applications.
Depending on the formulation and technical requirements, Polyacrylamide may be used for:
- Enhanced oil recovery (EOR)
- Drilling fluids
- Water control treatments
Oilfield applications require specific PAM grades with controlled molecular weight and performance characteristics.
PAM for Paper Manufacturing
Polyacrylamide is used in the paper industry as a retention aid and drainage aid.
It can help improve:
- Fiber retention
- Paper strength
- Drainage performance
- Production efficiency
The suitable PAM type depends on the paper production process and formulation requirements.
How to Choose the Right PAM Grade?
Selecting the correct Polyacrylamide depends on several factors:
Ionic Type
- Anionic PAM
- Cationic PAM
- Nonionic PAM
Molecular Weight
Higher molecular weight generally provides stronger bridging ability, but the suitable range depends on the application.
Charge Density
Charge degree affects the interaction between PAM molecules and suspended particles.
Application Conditions
Important factors include:
- Wastewater composition
- pH value
- Suspended solids type
- Treatment equipment
- Required settling performance
Professional jar testing is recommended before large-scale use.
