DA403 Medium High Viscosity High Solid PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC NSF Certified for Drinking Water and Wastewater Treatment
PolyDADMAC DA403 – NSF Certified High Solid Polymer with Enhanced Floc Strength
PolyDADMAC, also known as PDADMAC, PDMDAAC, PolyDMDAAC, or Poly (DADMAC), is a high charge density cationic polymer widely used as a primary coagulant in water and wastewater treatment.
DA403 is part of the BLU DA Series high solid content (around 40%) grades, designed to provide enhanced flocculation performance while maintaining efficient storage and dosing advantages.
Compared with DA402, DA403 offers stronger floc formation and improved sedimentation performance, making it suitable for more demanding water treatment conditions where higher turbidity or more stable floc structure is required.
Bluwat Chemicals is a professional manufacturer of water treatment chemicals with over 25 years of experience, exporting to more than 80 countries worldwide. We provide customized solutions based on real wastewater testing and industry-specific applications.
Key Advantage:
Our PolyDADMAC products are NSF certified for drinking water treatment chemicals, ensuring compliance with strict international standards for potable water applications. This makes DA403 a reliable choice for both municipal drinking water plants and industrial water systems requiring certified products.
