BWD-01 Dicyandiamide Formaldehyde Resin Decolourant Chemical for Textile Industry Wastewater Treatment
BWD-01 Water Decoloring Agent for Textile Dye Wastewater Treatment
High Performance Cationic Polymer for Reactive Dye Wastewater Color Removal COD Reduction and Flocculation Treatment
Product Overview
BWD-01 Water Decoloring Agent is a high efficiency organic cationic polymer specially developed for textile dye wastewater treatment applications.
It is widely used to remove color from reactive dyes disperse dyes acid dyes pigment wastewater printing wastewater and other high color industrial effluents.
Compared with traditional inorganic coagulants alone BWD-01 provides significantly better color removal performance for soluble dye molecules that are difficult to remove through conventional treatment methods.
The product is based on dicyandiamide formaldehyde resin technology and works through strong charge neutralization and flocculation mechanisms.
It rapidly destabilizes colored pollutants and forms dense flocs that settle quickly.
Bluwat Chemicals has more than 25 years of manufacturing experience in water treatment chemicals and exports products to over 80 countries worldwide.
Daily wastewater jar testing is carried out in the laboratory to help customers optimize treatment programs based on real wastewater conditions.

The Problem in Textile Wastewater Treatment
Textile dyeing and printing wastewater is one of the most difficult industrial wastewaters to treat due to:
- High color intensity
- Complex dye structures
- High COD levels
- Poor biodegradability
- Large fluctuations in wastewater quality
Many dye molecules remain dissolved in water and cannot be effectively removed by PAC or PAM alone.
As environmental discharge standards become stricter worldwide textile factories require more efficient decolorization solutions that can improve effluent quality while reducing operational costs.
Why Conventional Treatment Often Fails
Traditional coagulation systems mainly rely on inorganic coagulants such as PAC alum or ferric salts.
These chemicals are effective for suspended solids removal but often show limited performance for soluble dye molecules especially reactive dyes and water soluble pigments.
Common Problems
- Residual color after sedimentation
- Excessive sludge generation
- High chemical consumption
- Unstable treatment results
- Difficulty meeting discharge standards
For many textile plants a specialized decolorizing polymer is necessary to achieve stable color removal performance.
The BWD-01 Solution
BWD-01 is designed specifically for difficult color removal applications.
The product rapidly reacts with negatively charged dye molecules in wastewater destabilizing them and forming larger flocs that can be removed through sedimentation or flotation systems.
Typical Treatment Advantages
- 50 to 99 percent color removal efficiency
- Significant COD reduction
- Faster settling performance
- Lower sludge volume
- Reduced coagulant dosage
- Improved effluent clarity
- Better compatibility with PAC and PAM systems
Recommended Treatment Sequence
BWD-01 → PAC → pH Adjustment → PAM

How BWD-01 Works
BWD-01 works mainly through charge neutralization and adsorption bridging.
The cationic polymer rapidly reacts with negatively charged dye molecules suspended or dissolved in water.
After destabilization the contaminants combine into larger flocs that can be separated through sedimentation or dissolved air flotation systems.
This process significantly improves wastewater clarity and reduces residual color.
Recommended Jar Test Procedure
Step 1
Add BWD-01 into wastewater sample under rapid mixing conditions.
Step 2
Add PAC if necessary to improve coagulation performance.
Step 3
Adjust pH value to around 7 to 8 for optimized flocculation.
Step 4
Add PAM flocculant to accelerate settling and strengthen flocs.
Step 5
Observe settling speed sludge formation and final water clarity.

How To Choose the Correct Decolorizing Agent
Choose Based on Dye Type
Different dyes require different treatment approaches. Reactive dye wastewater usually needs stronger decolorization capability.
Consider COD and Color Intensity
High COD wastewater may require combined treatment with PAC and PAM.
Check Existing Treatment Process
The best dosing position depends on whether the system uses biological treatment sedimentation or flotation.
Perform Jar Testing
Laboratory testing remains the most reliable way to optimize dosage and treatment sequence.
Why Choose Bluwat Chemicals
Main products include Water Decoloring Agent Polyacrylamide PolyDADMAC PAC ACH Polyamine and Ferric Sulphate.
