Why DCA for ZLD

DCA (Dicyandiamide Cationic Resin)—an ion exchanger polymer in liquid form—targets persistent dyes and colloids in textile effluents. It accelerates floc formation and clarification, stabilizes downstream RO/evaporation units, and helps mills meet global standards across Asia, Europe, the Middle East, and the Americas.

Performance Highlights

• High decolorization on reactive/acid/disperse/direct dyes
• COD reduction and improved RO membrane protection
• Lower sludge vs. inorganic-only programs
• Seamless with PAC/ACH/PolyDADMAC; ETP/ZLD compatible
• Liquid handling: precise metering, easy automation
