DA404 High Viscosity High Solid PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC NSF Certified for Heavy Duty Water Treatment and Sludge Separation
PolyDADMAC DA404 – NSF Certified High Solid High Viscosity Polymer for Heavy Duty Treatment
PolyDADMAC, also known as PDADMAC, PDMDAAC, PolyDMDAAC, or Poly (DADMAC), is a high charge density cationic polymer widely used in coagulation and flocculation processes.
DA404 is a high viscosity grade within the 40% solid content BLU DA Series, engineered for heavy-duty water treatment applications where strong floc formation, fast sedimentation, and efficient solid-liquid separation are required.
Compared with DA403, DA404 delivers denser flocs, faster settling rates, and improved sludge compaction, making it ideal for high turbidity water and complex industrial wastewater conditions.
Bluwat Chemicals is a global manufacturer of water treatment chemicals with over 25 years of experience. We export to more than 80 countries and provide customized treatment solutions based on real water testing.
