Instructions for Use
Preparation concentration
The product is typically prepared as a 0.05%–0.5% (W/W) solution, with 0.1% recommended.
01
Dissolution method
Disperse the product evenly under stirring. Dissolution takes about 1 hour until complete.
02
Water quality requirements
Use low-hardness water. Avoid metal containers that may affect performance.
03
Temperature control
Higher temperature accelerates dissolution, but water temperature should generally not exceed 50°C.
04
Synergistic use
When used with inorganic coagulants, add inorganic coagulant (e.g., PAC) first, then APAM for better performance.

Frequently Asked Questions (FAQ)
Q: 1. What is the difference between anionic, cationic, and non-ionic polyacrylamide?
A: Anionic (APAM): Suitable for neutral or alkaline wastewater with positively charged suspended particles, such as steel, electroplating, and coal washing wastewater
Cationic (CPAM): Suitable for acidic or high organic content wastewater with negatively charged particles, such as alcohol, beer, and dyeing wastewater
Non-ionic (NPAM): Suitable for acidic suspended wastewater with good electrolyte tolerance
Q: 2. How to select molecular weight and charge density?
A: Molecular weight: high molecular weight (>15 million) for inorganic suspended solids; medium/low for deep penetration applications
Hydrolysis degree: 20%–30% for most industrial wastewater; customized for special applications
Q: 3. Recommended dosage?
A: Typical dosage is 0.01–10 ppm (0.01–10 g/m³). Lower dosage is required when used with inorganic coagulants. Jar testing is recommended.
Q: 4. Shelf life of prepared solution?
A: Fresh solution is recommended. After 24 hours, viscosity decreases and performance may be affected.
Q: 5. Precautions?
A: Store in a dry, cool place, avoid moisture
Avoid contact with strong oxidants and metal ions
Wear protective equipment during operation
Avoid using metal containers for dissolution
Q: 6. Environmental impact?
A: APAM is non-toxic and non-corrosive. It does not harm aquatic organisms at proper dosage in stormwater treatment. However, dosage control is required due to residual acrylamide monomer.
Q: 7. Shelf life?
A: 2 years under cool and dry storage conditions.
