Food-grade polyacrylamide is used in drinking water treatment and food processing where safety is paramount. NSF/ANSI 60 certification is the gold standard — it means the product is safe for contact with potable water. We produce NSF-certified PAM at our Zhengzhou factory specifically for these applications.
Food-Grade PAM Applications
| Application | PAM Type | Certification | Dosage |
|---|---|---|---|
| Drinking water clarification | APAM 10-15M MW | NSF/ANSI 60 | 0.1-0.5 ppm |
| Sugar juice clarification | NPAM 8-12M MW | NSF/ANSI 60 | 2-5 ppm |
| Beer/wine clarification | APAM 8-12M MW | NSF/ANSI 60 | 1-3 ppm |
| Juice processing | APAM 10-15M MW | NSF/ANSI 60 | 1-5 ppm |
| Dairy processing | APAM 8-12M MW | NSF/ANSI 60 | 0.5-2 ppm |
What NSF/ANSI 60 Certification Means
NSF/ANSI 60 is the American National Standard for drinking water treatment chemicals. It certifies that a product:
- Contains no harmful contaminants above safe limits
- Does not leach toxic substances into water
- Has residual monomer ≤0.05% (500 ppm acrylamide)
- Has been tested by an independent third-party lab
- Meets strict manufacturing and quality control standards
NSF certification is required by law in the United States for any chemical used in drinking water treatment. Many other countries (Canada, Australia, EU) recognize NSF certification as equivalent to their own standards.
Our NSF/ANSI 60 certified PAM is engineered for exactly this use case, with batch-level quality control from our Zhengzhou facility.
Residual Monomer: The Critical Specification
Acrylamide monomer is a neurotoxin. PAM is made by polymerizing acrylamide monomers, but some unreacted monomer always remains. The key specification is residual monomer content.
- Industrial-grade PAM: ≤0.1% (1000 ppm) residual monomer — acceptable for non-food applications
- Food-grade PAM: ≤0.05% (500 ppm) residual monomer — NSF certified, safe for drinking water
- Ultra-pure PAM: ≤0.01% (100 ppm) residual monomer — available on request for pharmaceutical applications
At 0.05% residual monomer and typical dosage of 0.5 ppm PAM in drinking water, the acrylamide concentration in the final water is approximately 0.00025 ppm — well below the EPA limit of 0.001 ppm (1 ppb).
Drinking Water Treatment
Municipal water treatment plants use NSF-certified APAM as a coagulant aid after alum or ferric chloride dosing. The PAM bridges coagulated particles into large, fast-settling flocs.
Typical process:
- Add alum or ferric chloride (primary coagulant)
- Rapid mix 1-2 minutes
- Add NSF-certified APAM at 0.1-0.5 ppm
- Slow mix 5-10 minutes to build flocs
- Settle in clarifier (2-4 hours)
- Filter through sand/anthracite filters
- Disinfect with chlorine or ozone
NSF-certified APAM improves clarification efficiency by 20-40% compared to coagulant alone, reducing turbidity from 10-50 NTU to <1 NTU.
Food and Beverage Processing
Food processors use NSF-certified PAM for juice clarification, beer/wine clarification, and dairy processing. The polymer must not impart any taste, odor, or color to the final product.
Sugar mills use NSF-certified NPAM for juice clarification because nonionic PAM does not introduce any ionic contamination that could affect sugar crystallization.
Breweries use NSF-certified APAM as a fining agent to clarify beer before bottling. Dosage: 1-3 ppm. The PAM flocculates yeast and protein particles, producing crystal-clear beer.

Our NSF-Certified PAM
We produce NSF/ANSI 60 certified PAM at our Zhengzhou factory:
- APAM for drinking water: 10-15M MW, 20-30% hydrolysis, ≤0.05% residual monomer
- NPAM for sugar/food: 8-12M MW, 0% ionic charge, ≤0.05% residual monomer
- APAM for beverages: 8-12M MW, 15-25% hydrolysis, ≤0.05% residual monomer
All grades: solid content ≥92%, dissolution time ≤90 minutes. NSF certificate on file and provided with every shipment.
MOQ: 500kg for first orders. Standard delivery: 7-10 days. We currently supply NSF-certified PAM to water utilities and food processors in North America, Europe, Australia, and Asia.
Documentation and Compliance
Every shipment of NSF-certified PAM includes:
- NSF/ANSI 60 certificate (copy)
- Certificate of Analysis (COA) showing residual monomer ≤0.05%
- Material Safety Data Sheet (MSDS)
- Packing list and commercial invoice
- Batch traceability documentation
For regulatory compliance, we maintain full documentation of manufacturing, testing, and quality control for each batch. This documentation is available for audit by regulatory agencies (EPA, FDA, NSF, etc.).
