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
