What is a water decolorizing agent?

KR-801 is a cationic polymer compound of cyanoguanidine series, which has various functions such as decolorization, flocculation, and CODcr degradation. It is mainly used to treat wastewater from high concentration and high chromaticity dyes, printing, and intermediate dyeing processes, especially for the treatment of wastewater from reactive dyes, acidic dyes, and dispersed dyes.
KR-801 water decolorizing agent can be used to treat industrial wastewater in industries such as textiles, printing and dyeing, pharmaceuticals, papermaking, and chemical industry, with a decolorization rate of over 95% and a CODcr removal rate of over 65%. When using, it is recommended to dilute KR-801 with 10 to 40 times water and directly add it to the wastewater. After stirring for a few minutes, precipitate or perform air flotation to obtain clear water after decolorization. In addition, adjusting the pH value of wastewater to 7 to 10 can improve treatment efficiency. When the color and CODCr value of the wastewater are high, in order to save treatment costs, KR-801 can be alternately used with polyaluminum chloride (PAC), but KR-801 and PAC cannot be mixed together. Whether to add polyaluminum chloride first or use KR-801 first should be determined based on laboratory testing and processing.
