In pigment, dye, and coating wastewater effluent treatment, a water decoloring agent like BWD-01 provides significant benefits due to its strong affinity for colorants and its ability to reduce contaminants. Here’s how it works in this challenging application:

1. Effective Color Removal: BWD-01 targets intense pigments and dyes typically present in effluent from pigment and coating industries. Its cationic polymer structure binds with the anionic dye and pigment molecules, neutralizing their charges, which allows them to aggregate and be removed more effectively. This results in high decolorization rates (up to 99%) even for complex, highly concentrated color effluents.

2. Reduction of COD and TSS: Pigment and dye effluents often have high COD (Chemical Oxygen Demand) and TSS (Total Suspended Solids) levels due to organic compounds and particulate matter. BWD-01 flocculates these particles, lowering COD by up to 80% and effectively reducing TSS levels, making the effluent cleaner and easier to process or discharge.

3. Improved Flocculation and Sedimentation: By facilitating the formation of larger flocs, BWD-01 enhances sedimentation, leading to faster settling and clearer treated water. This is especially valuable in pigment and coating wastewater, where suspended solids and insoluble particles are common and need efficient removal to meet regulatory standards.

4. Less Sludge Production: Compared to traditional inorganic coagulants, BWD-01 produces less sludge, which is advantageous for the pigment and coating industries. Reduced sludge volume decreases disposal costs and the environmental footprint of the treatment process, making it a cost-effective and sustainable choice.

5. Compatibility with Various Dyes and Pigments: BWD-01 can decolorize wastewater containing a wide range of dyes and pigments, including Acid, Reactive, Disperse, and Direct dyes, which are common in coating and pigment effluents. This versatility makes it suitable for use in diverse applications across industries.

6. Eco-friendly and Non-toxic: BWD-01’s formulation is free of harmful metals and chlorinated compounds, ensuring that the treated water is safe for discharge without introducing secondary pollutants. This non-toxic composition is particularly beneficial for meeting environmental regulations and reducing the ecological impact of treated effluent.

Description:

BWD-01 Water Decoloring Agent is a highly effective and specialized product designed for the removal of color from textile dyeing wastewater, particularly for hydrophilic dyes such as reactive dyes, acid dyes, disperse dyes, and others. With its fast-acting formula and low dosage, BWD-01 is capable of quickly clearing the color and improving the settling of processing liquids, while also enhancing the removal rate of COD.

This new type of high-performance decolorizing flocculant is a chemical agent that is utilized for a range of applications, including the removal of color, flocculation, and CODcr reduction in wastewater generated by textile processing plants, dye industries, and other fields. Its high color removal ability is attributed to the large number of cations it provides, which neutralize the negative charges on dye molecules and promote the destabilization of flocs through hydrolysis.

BWD-01 Water Decoloring Agent is a medium molecular weight polymeric coagulant and a highly efficient decoloring flocculant that is essential for industries generating colored effluents. If left untreated, these effluents can have severe consequences on reusable water resources. In water-scarce areas, BWD-01 is an essential tool that facilitates the recycling of industrial effluent into process water, thereby solving the problem of colored effluents generated by these industries.
