BWD-01 Water Decoloring Agent for Textile Dye Wastewater TreatmentHigh Performance Cationic Polymer for Reactive Dye Wastewater Color Removal COD Reduction and Flocculation Treatment Product OverviewBWD-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.

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 FailsTraditional 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
For many textile plants a specialized decolorizing polymer is necessary to achieve stable color removal performance. The BWD-01 SolutionBWD-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
Recommended Treatment SequenceBWD-01 → PAC → pH Adjustment → PAM Specifications
Application IndustriesTextile Dyeing WastewaterUsed for reactive dyes sulfur dyes disperse dyes acid dyes and pigment wastewater treatment. Printing Ink WastewaterProvides effective color reduction for water based printing ink wastewater systems. Paper Mill WastewaterImproves color removal in recycled paper and pulp wastewater treatment. Pigment Manufacturing WastewaterHelps reduce color and COD in pigment production wastewater. Chemical Industry WastewaterSuitable for high color industrial effluents requiring advanced decolorization. How BWD-01 WorksBWD-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 ProcedureStep 1Add BWD-01 into wastewater sample under rapid mixing conditions. Step 2Add PAC if necessary to improve coagulation performance. Step 3Adjust pH value to around 7 to 8 for optimized flocculation. Step 4Add PAM flocculant to accelerate settling and strengthen flocs. Step 5Observe settling speed sludge formation and final water clarity. Bluwat Chemicals laboratory can help customers evaluate wastewater samples and recommend suitable treatment programs. How To Choose the Correct Decolorizing AgentChoose Based on Dye TypeDifferent dyes require different treatment approaches. Reactive dye wastewater usually needs stronger decolorization capability. Consider COD and Color IntensityHigh COD wastewater may require combined treatment with PAC and PAM. Check Existing Treatment ProcessThe best dosing position depends on whether the system uses biological treatment sedimentation or flotation. Perform Jar TestingLaboratory testing remains the most reliable way to optimize dosage and treatment sequence.

FAQWhat types of dyes can BWD-01 removeBWD-01 is highly effective for reactive dyes disperse dyes acid dyes sulfur dyes and pigment wastewater. Can BWD-01 be used together with PAC and PAMYes. In many applications BWD-01 works best when combined with PAC and PAM in a complete coagulation and flocculation system. Does BWD-01 reduce CODYes. Besides color removal the product can also significantly reduce COD levels in many industrial wastewaters. Is jar testing necessary before useYes. Wastewater characteristics vary greatly between factories so jar testing is recommended to optimize dosage and treatment sequence. What packaging options are availableStandard packaging includes 30kg drums 250kg drums and 1250kg IBC containers. Short Product DescriptionBWD-01 Water Decoloring Agent is a high performance cationic polymer designed for textile dye wastewater treatment. It effectively removes color reduces COD improves flocculation and enhances sedimentation performance in industrial wastewater systems worldwide. |
