Dicyandiamide Resin Decolorizing Agent Decolourant Water Purification Chemicals for Water Treatment
Dicyandiamide Resin Decolorizing Agent Decolourant Water Purification Chemicals for Water Treatment
Product Overview
BWD-01 Dicyandiamide Resin Decolorizing Agent is a high-efficiency water purification chemical specially developed for industrial wastewater decolorization, COD reduction, and clarification treatment applications. The product is widely used in textile dyeing wastewater, pigment wastewater, printing ink wastewater, paper mill wastewater, landfill leachate, and chemical wastewater treatment systems.
Industrial wastewater often contains dissolved dyes, organic pigments, colloidal particles, and suspended solids that are difficult to remove through conventional inorganic coagulants alone. Many wastewater treatment plants face challenges such as residual color, unstable sedimentation, excessive sludge generation, and high operating costs.
BWD-01 Water Decolourant is designed to rapidly destabilize color substances and improve coagulation performance, helping achieve clearer treated water and more stable purification efficiency.
Why High-Color Wastewater Requires Specialized Water Purification Chemicals
Common Problems in Industrial Water Treatment
Industrial wastewater from textile dyeing, printing, paper production, and chemical manufacturing often contains:
- Reactive dyes
- Acid dyes
- Organic pigments
- Fine colloidal particles
- Suspended solids
- High COD contaminants
Traditional inorganic coagulants may not effectively remove dissolved color molecules and stable colloids, especially in high-color wastewater systems.
This may result in:
- Dark final effluent
- Poor discharge quality
- Slow sedimentation
- Excess sludge generation
- High chemical dosage consumption
- Unstable treatment performance
Specialized organic decolorizing chemicals are therefore important for improving industrial wastewater purification performance.
Solution for Wastewater Decolorization and Purification
High-Efficiency Dicyandiamide Resin Decolourant
BWD-01 works through strong cationic charge neutralization and polymer flocculation mechanisms.
The product rapidly reacts with negatively charged dye molecules, pigments, and colloidal particles in wastewater, helping destabilize color substances and form dense flocs for easier sedimentation or flotation separation.
Treatment performance:
- Color removal efficiency: 50%–99%
- COD reduction efficiency: 50%–80%
- Faster flocculation and settling
- Lower sludge generation
Compared with traditional inorganic coagulants, BWD-01 provides stronger color removal performance and more stable clarification efficiency.
For difficult wastewater systems, the product is commonly used together with PAC and PAM.
Recommended treatment sequence:
BWD-01 → PAC → PAM
Recommended operating pH:
7.5–8.0

How It Works
Working Principle of Water Purification Chemical
The treatment process mainly includes:
- Charge neutralization
- Dye destabilization
- Polymer bridging
- Flocculation and sedimentation
After dilution, BWD-01 is added directly into wastewater.
The cationic polymer rapidly adsorbs negatively charged dye molecules and colloidal particles, helping form large and dense flocs.
The flocs are then removed through sedimentation or dissolved air flotation systems.
For wastewater with high COD or difficult color removal requirements, PAC and PAM are usually combined to improve treatment performance and clarification efficiency.
How To Choose the Right Decolorizing Chemical
Choose According to Wastewater Type
Different wastewater systems contain different contaminants:
- Textile wastewater contains soluble dyes
