DA205 Very High Viscosity PolyDADMAC Cationic Polymer Coagulant PDADMAC PDMDAAC for Extreme Wastewater Treatment and Sludge Thickening
PRODUCT INTRODUCTION
PolyDADMAC DA205 – Very High Viscosity Polymer for Maximum Floc Strength
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.
DA205 is a very high viscosity grade within the BLU DA Series, engineered for maximum floc strength, superior bridging capability, and enhanced solid-liquid separation efficiency. It is specifically designed for extreme treatment conditions where conventional coagulants or lower viscosity polymers are not sufficient.
Compared to DA204, DA205 produces larger, heavier, and more compact flocs, making it ideal for difficult wastewater with high suspended solids, complex contaminants, or demanding sludge handling requirements.
Bluwat Chemicals is a professional manufacturer with over 25 years of experience in water treatment chemicals, exporting to more than 80 countries. We provide customized treatment solutions based on real wastewater testing and field applications.
Our PolyDADMAC products are manufactured under strict quality control systems and meet requirements for drinking water treatment chemicals, including NSF-related standards, ensuring safety and reliability in potable water applications.
