In physicochemical treatment processes, alongside conventional coagulants, Color Removal (decolorant) chemicals are also used for removing color from industrial wastewater containing dyes. Color Removal Chemicals used in wastewater are polymer-based and can be cationic, anionic, or non-ionic in structure. These color removers, which are organic polymeric coagulants with high color removal efficiency, are typically used to eliminate dye pigments in textile wastewater. In addition to color removal, they also significantly reduce COD (Chemical Oxygen Demand), turbidity, and TSS (Total Suspended Solids).
While the primary application areas of Color Removers are textile wastewater and leachate, they are also effective in treating wastewater from metal, food, chemical, beverage, mining, leather, petroleum, paper industries, and organized industrial zones. In recent years, Color Removal Chemicals have increasingly been used in wastewater treatment plants in Turkey to remove color from industrial wastewater containing dyes—especially from textile effluents—and to meet discharge color standards. According to data obtained from many facilities, Color Removers provide effective color removal.
