Coagulation Flocculation Water Decoloring Agent For Cutting Fluid Metalworking Fluid Machining Coolant Water Treatment
DCA-58 is a high-performance water decolorant with 50% solid content specifically formulated for wastewater color treatment applications in Bangladesh and international markets.
Chemical Type: Quaternary Ammonium Cationic Polymer
Form: Colorless to yellowish transparent liquid
Primary Functions: Color removal, COD reduction, and flocculation
- Breaking Emulsions and Enhancing Oil Removal: Machining and metalworking fluids often contain emulsified oils, which can be challenging to separate. DCA-58 destabilizes these emulsions, allowing oil particles to coagulate and separate more efficiently. This improves the effectiveness of oil removal systems and helps reduce oil levels in the treated water.
- Effective Color Removal from Additives and Dyes: Metalworking fluids often contain dyes and additives that impart color to the wastewater. DCA-58, as a cationic polymer, binds to these dye molecules, neutralizing and aggregating them for efficient color removal. This results in a clearer effluent and supports compliance with discharge standards for color.
- Reduction of COD and Total Suspended Solids (TSS): The presence of organic compounds, oils, and metal particulates often contributes to high COD and TSS in metalworking wastewater. DCA-58 helps by coagulating these contaminants into larger flocs, allowing for a reduction in COD (up to 80%) and TSS, resulting in a cleaner effluent.
- Improving Flocculation and Sedimentation: DCA-58 enhances the flocculation process, aggregating fine metal particulates and other solids into larger flocs that settle quickly in sedimentation tanks. This improves the sedimentation process, producing a clearer supernatant and reducing the amount of suspended solids in the discharged water.
- Minimizing Sludge Production: Compared to conventional inorganic coagulants, DCA-58 generates less sludge, which reduces sludge handling and disposal costs. In metalworking applications where large volumes of wastewater are generated, this translates to significant operational savings.
- Non-toxic and Eco-friendly: DCA-58 is free from heavy metals and chlorinated compounds, making it an environmentally friendly choice. This ensures that treated wastewater does not introduce secondary pollutants into the environment, supporting compliance with environmental regulations.
- Versatility Across Metalworking Applications: DCA-58 is effective in treating a range of contaminants found in metalworking fluids, including oils, dyes, and particulate matter. This makes it suitable for various metalworking processes, from cutting and grinding to drilling and machining, where coolants and lubricants are widely used.
