Polydadmac｜PDADMAC｜pD
Polydiallyldimethylammonium Chloride (PDADMAC) is a primary coagulant and flocculant aid for drinking water treatment. With excellent charge neutralization and adsorption bridging properties, PDADMAC can effectively flocculate, decolorize, and remove algae and organic substances, ensuring clean and safe drinking water. Meanwhile, our Polydadmac product has obtained NSF certification, so it can be safely used in drinking water treatment.

Application
Polydadmac is widely used in various fields, including:
Drinking Water Treatment
Wastewater Treatment
Mining Process
Textile Color Fixing Agent
Paper Making
Sugar Industry
Oil Industry
Sludge Dewatering
Usage Instructions
For water treatment applications, the dosage of Polydadmac depends on the turbidity and concentration of the source water or wastewater. The most cost-effective dosage should be determined through jar testing. When used alone, PDADMAC should be diluted to a concentration of 0.5% to 0.05% (solid content). To ensure uniform mixing with other chemicals and to prevent floc breakage, careful attention should be paid to the dosing point and stirring speed.
Storage & Handling
To ensure the effectiveness of Polydadmac in water treatment, correct storage and handling are important:
- Store in a cool, dry, well-ventilated area
- Protect from direct sunlight and freezing
- Use PPE (gloves, goggles) when handling the concentrate
- Avoid mixing with anionic polymers directly
