CW-08 Water Decoloring Agent (CAS 55295-98-2): Dicyandiamide Resin for Textile Wastewater Color & COD Removal

We are proud to present the CW-08 Water Decoloring Agent (CAS No. 55295-98-2), a premium-grade dicyandiamide formaldehyde resin specially formulated for industrial wastewater treatment. As a colorless to light-color sticky liquid with a solid content of ≥50%, CW-08 delivers exceptional decolorization performance coupled with significant COD reduction—removing approximately 60% of COD in a single treatment step. This dual-function capability makes CW-08 a cost-effective and operationally efficient solution for textile dyeing & printing mills, dyestuff & pigment manufacturers, ink producers, and papermaking facilities worldwide.

• Exceptional Color Removal: Effectively treats wastewater containing Reactive, Acid, Disperse, Direct, Sulphur, and Vat dyes, delivering crystal-clear effluent suitable for discharge or reuse.
• Dual-Function Performance: Simultaneously removes color and reduces COD by approximately 60%, eliminating the need for multiple treatment chemicals and simplifying the wastewater treatment process.
• Broad pH Compatibility: Delivers optimal results when the wastewater pH is adjusted to 6–10, providing operational flexibility across diverse industrial effluent streams.
• Easy Application: Simply dilute CW-08 with 10–40 times water before direct addition to the wastewater stream. After several minutes of stirring, clear water is obtained through precipitation or air-flotation separation.
• Versatile Industrial Use: Beyond wastewater treatment, CW-08 also serves as an effective retention agent in paper and pulp production processes, adding value across the manufacturing workflow.
• Customizable Formulations: Our product can be tailored to meet your specific operational requirements, ensuring optimal performance under your unique process conditions.

The textile industry is one of the largest consumers of synthetic dyes and generates wastewater with intense coloration and high organic load. CW-08 is specifically engineered for textile effluent, achieving superior decolorization across all major dye classes including reactive, acid, disperse, direct, sulphur, and vat dyes. Its rapid flocculation kinetics ensure efficient treatment in both continuous and batch operations.

Dyestuff and pigment production facilities face the challenge of treating concentrated mother liquors and wash waters containing high-strength colorants. CW-08 provides robust performance in these demanding conditions, effectively precipitating color bodies and significantly reducing organic pollutant loads.

Printing and ink manufacturing effluents contain a complex mixture of pigments, binders, and solvents. CW-08 effectively destabilizes these colloidal systems, enabling efficient solid-liquid separation and producing clarified water that meets discharge standards.

In paper and pulp production, CW-08 serves a dual purpose: as a wastewater decolorizing agent for bleach plant effluents and deinking wastewater, and as a retention agent in the papermaking process itself. This versatility reduces chemical inventory and simplifies procurement for integrated pulp and paper mills.

1. Dilution: Dilute CW-08 with 10–40 times the volume of clean water to ensure proper dispersion.
2. pH Adjustment: Optimize wastewater pH to 6–10 for maximum decolorization and COD removal efficiency.
3. Dosing: Add the diluted CW-08 solution directly to the wastewater stream with adequate mixing.
4. Mixing: Stir for several minutes to allow complete contact between the decoloring agent and the color-causing compounds.
5. Separation: Separate the treated water from the formed flocs via sedimentation or dissolved air flotation (DAF).

CW-08 is manufactured under strict quality control standards, ensuring batch-to-batch consistency and reliable field performance. With CAS registration 55295-98-2, the product is fully traceable and compliant with international chemical management regulations. Our technical support team is available to assist with dosing optimization, jar testing, and on-site troubleshooting. Furthermore, we offer custom formulations to align CW-08’s properties with your specific wastewater characteristics and treatment objectives, delivering a truly tailored solution that maximizes both environmental compliance and operational cost-effectiveness.
