DA203 Medium High Viscosity PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC for Water Treatment Flocculation and Effluent Clarification
PRODUCT INTRODUCTION
PolyDADMAC DA203 – Medium High Viscosity Liquid Cationic Polymer
PolyDADMAC, also known as PDADMAC, PDMDAAC, or PolyDMDAAC, is a high charge density cationic polymer widely used as a primary coagulant in water and wastewater treatment.
DA203 is a medium-high viscosity grade from the BLU DA Series, designed to provide stronger floc formation and improved sedimentation compared to lower viscosity grades. It is particularly suitable for treating wastewater with higher suspended solids or requiring stronger floc structure.
Bluwat Chemicals is a professional manufacturer of water treatment chemicals with over 25 years of experience. We export to more than 80 countries and provide customized solutions based on real wastewater samples and laboratory jar testing.
Our PolyDADMAC products are produced under strict quality control and meet requirements for drinking water treatment chemicals, including NSF-related standards, ensuring safe and reliable use in potable water applications.
