The circulating water decolorizer is a kind of chemical reagent used to remove the pigment components in circulating water, which is widely applied in industrial wastewater treatment, especially in industries such as printing and dyeing, papermaking, chemical engineering, and ink manufacturing. The following is a detailed introduction to the circulating water decolorizer:
Circulating water flocculating decolorizer: It is usually a quaternary ammonium cationic polymer compound. By combining with the pigments and suspended solids in the water, it forms flocs that precipitate, thus achieving the purposes of decolorization and removal of pollutants. The circulating water decolorizing flocculant can be used for the treatment of industrial wastewater from industries such as printing and dyeing and ink manufacturing. The decolorizer has the advantages of rapid reaction, high-efficiency decolorization, and reduction of COD (chemical oxygen demand), etc.
Application Scenarios
Industrial wastewater treatment: In industries such as printing and dyeing, papermaking, and chemical engineering, the circulating water decolorizer can be used to remove high-color pollutants in wastewater and reduce COD and BOD (biochemical oxygen demand).
Treatment of circulating water in spray towers: The circulating water in spray towers will gradually change color during repeated use. The decolorizer can effectively remove pigments and prevent the accumulation of pollutants.
Municipal sewage treatment: In municipal sewage treatment, the decolorizer can be used to remove the colored substances in sewage and improve the treatment efficiency.
Usage Methods
Dilution and dosing: Usually, the decolorizer needs to be diluted into an aqueous solution with a concentration of 5% - 50%, and then dosed into the circulating water through a dosing pump.
pH adjustment: In order to achieve the best treatment effect, it is recommended to adjust the pH value of the wastewater to 7 - 10.
Combined use: When the color and COD of the wastewater are relatively high, it can be used in combination with other agents such as polyaluminium chloride, but attention should be paid to the dosing sequence.
With the increasingly strict environmental protection regulations, the market demand for high-efficiency and environmentally friendly water decolorizers continues to increase. In the future, the research and development of water decolorizers will tend to develop in the direction of higher efficiency and greater environmental friendliness.
