Targeting Complex Color Bodies
DCA—a dicyandiamide formaldehyde resin—binds finely dispersed pigments, stabilizers, and surfactants that resist conventional coagulation. It supports fast floc growth and better separation, reducing carryover to biological stages and improving final effluent clarity.
Benefits for Ink/Pigment Plants
- Rapid color removal for high-strength pigment/ink loads
- Improved COD knockdown; less stress on aeration
- Lower sludge vs. metal-salt-dominant programs
- Works with PAC/ACH/PolyDADMAC; minimal retrofits
- Liquid dosing; easy automation and control
