CW-08 Water Decoloring Agent: High-Performance Dicyandiamide Resin for Industrial Wastewater Treatment

Industrial wastewater containing synthetic dyes and organic pollutants poses a persistent challenge for manufacturers across the globe. As environmental regulations tighten in Europe and North America, facilities must adopt high-efficiency treatment chemicals that deliver reliable color and COD removal. CW-08 is a quaternary ammonium cationic polymer based on dicyandiamide formaldehyde resin, purpose-engineered to meet these exacting demands with proven performance and operational flexibility.

CW-08 is a high-performance water decoloring agent whose main active component is dicyandiamide formaldehyde resin. With CAS No. 55295-98-2 and a specific gravity of 1.1–1.3, this cationic polymer delivers dual-action performance: superior color removal alongside approximately 60% COD reduction. Its quaternary ammonium structure enables rapid charge neutralization and flocculation of negatively charged dye molecules, making it exceptionally effective across textile, printing, dyeing, paper-making, mining, and ink wastewater streams. The product can also be manufactured to customer-specific requirements, offering tailored performance for unique treatment scenarios.

• Dual-Action COD and Color Removal: CW-08 achieves approximately 60% COD reduction while delivering color removal rates exceeding 95% for reactive, acidic, and disperse dyestuffs. This dual functionality reduces the need for supplementary chemicals and simplifies treatment train design.
• High Active Content: With a minimum solid content of 50%, CW-08 provides concentrated performance that lowers shipping volumes and on-site storage requirements compared to diluted alternatives, delivering superior cost-efficiency per treatment unit.
• Wide pH Adaptability: Unlike aluminum- and iron-based coagulants that demand narrow pH windows, CW-08 maintains stable decolorization performance across a broad pH range, minimizing chemical pre-adjustment costs.
• Low Sludge Generation: The product generates significantly less sludge volume compared to traditional inorganic coagulants, reducing solid waste disposal expenses and simplifying downstream dewatering operations.
• Rapid Settling Kinetics: Formed flocs settle within minutes, enabling high-throughput continuous flow treatment and reducing hydraulic retention time requirements—ideal for high-capacity industrial facilities.
• Custom Formulation Capability: CW-08 can be manufactured to meet specific customer requirements, providing tailored molecular weight, charge density, or viscosity for unique wastewater matrices and regional compliance standards.

• Textile and Dyeing Wastewater: Highly effective against reactive, acidic, and disperse dyestuffs used in fabric processing operations.
• Dyestuff Manufacturing Plants: Specifically designed for high-colority wastewater from dyestuffs production, achieving superior decolorization where conventional treatments fall short.
• Paper and Pulp Mills: Functions both as a color removal agent for bleaching and pulping effluent and as a retention agent in the paper production process, improving fiber and filler retention while reducing white water solids.
• Printing Ink Wastewater: Effectively removes pigments, dye carriers, and organic color bodies from printing and packaging industry discharge.
• Mining Industry Effluent: Treats process water containing suspended solids and color-imparting compounds from mineral processing and beneficiation operations.
• Municipal and Industrial Augmentation: Can be integrated into existing treatment trains as a polishing step for enhanced color and COD compliance.

For optimal performance, CW-08 should be diluted to a 10–50% working solution with clean water prior to dosing. Typical dosage rates range from 100 to 1,000 ppm depending on influent color intensity, COD load, and specific wastewater characteristics. The product is applied via in-line injection or rapid-mix chamber, followed by flocculation and sedimentation or dissolved air flotation (DAF). Jar testing is strongly recommended to establish the precise dosage for each wastewater matrix. As a cationic polymer, CW-08 is compatible with anionic polyacrylamide flocculants for enhanced floc strength in demanding applications.

CW-08 is purpose-built to meet the stringent requirements of European and North American water treatment markets. The product is backed by comprehensive technical documentation, consistent batch-to-batch quality control, and a reliable international supply chain. With custom manufacturing flexibility, customers can specify performance parameters tailored to their exact treatment objectives. Dedicated technical support—including jar testing guidance, dosing optimization, and system integration consulting—is available to ensure every customer achieves maximum treatment efficiency and regulatory compliance.

As industries face intensifying environmental standards and rising operational costs, CW-08 offers a proven, dual-action solution combining outstanding color removal with meaningful COD reduction. Its dicyandiamide formaldehyde resin chemistry, high solid content, and custom manufacturing capability make it a compelling choice for textile, dyestuff, paper, mining, and printing facilities worldwide.
