BV/ISO Certified Color Removal Agent: Dicyandiamide Formaldehyde Resin for Industrial Wastewater Treatment

We are pleased to introduce our BV/ISO Certified Dicyandiamide Formaldehyde Resin, a premium-grade color removal water treatment agent designed for high-efficiency decolorization of industrial wastewater. This colorless to yellowish translucid liquid with a solid content of ≥50% delivers outstanding color removal, superior COD reduction, and rapid flocculation—all while maintaining a non-polluting profile free from aluminum, chlorine, and heavy metal ions. With BV and ISO certifications, this product meets the most rigorous international quality and safety standards for global trade.

• Strong Decolorization: Highly effective in removing color from industrial wastewater across a broad spectrum of dye types including reactive, acid, disperse, direct, sulphur, and vat dyes.
• Superior COD Reduction: Achieves significant Chemical Oxygen Demand (COD) reduction alongside decolorization, streamlining the treatment process and reducing the need for additional chemical inputs.
• Faster Sedimentation & Better Flocculation: Promotes rapid formation of dense, easily settleable flocs, accelerating solid-liquid separation and increasing treatment capacity.
• Non-Polluting Formulation: Free from aluminum, chlorine, and heavy metal ions—ensuring treated effluent is safe for discharge and fully compliant with stringent environmental regulations.
• BV / ISO Certified: Independently tested and certified by Bureau Veritas (BV) and ISO standards, providing confidence in product quality, consistency, and international regulatory compliance.
• Excellent Water Solubility: Fully soluble in water, enabling easy dilution and uniform dispersion during application with no risk of clogging or uneven distribution in dosing systems.

Our dicyandiamide formaldehyde resin is extensively used in textile mills to treat highly colored effluent from dyeing and printing operations. It effectively removes reactive, acid, disperse, direct, sulphur, and vat dyes, producing clarified water that meets discharge standards for color and organic load.

Production facilities generating concentrated colorant waste streams benefit from the strong flocculation and decolorization properties of this resin, which effectively precipitates even high-concentration color bodies for efficient separation.

Ideal for treating printing ink effluents and papermaking wastewater, this product destabilizes pigment dispersions and removes lignin-derived color, ensuring compliance with environmental discharge limits.

With BV (Bureau Veritas) and ISO certifications, every batch of our dicyandiamide formaldehyde resin undergoes rigorous quality control testing before shipment. This includes viscosity measurement, solid content analysis, pH verification, specific gravity testing, and jar test performance evaluation. These certifications provide international buyers with documented assurance of product quality, safety, and consistency—essential requirements for import clearance and regulatory compliance in markets across Asia, Europe, the Middle East, and the Americas.

Combining strong decolorization performance, superior COD reduction, rapid flocculation kinetics, and a non-polluting chemical profile—all backed by BV/ISO certification—our color removal agent represents a reliable, high-quality choice for industrial wastewater treatment professionals worldwide. The product is available in bulk quantities with flexible packaging options and is supported by our technical team for dosing optimization and on-site application guidance.
