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 treatment Water Decoloring Agent can be used for the treatment of industrial wastewater in textile, printing and dyeing, pharmaceutical, papermaking, chemical and other industries, with a decolorization rate of over 95% and a CODcr removal rate of over 65%.
The steps of using KR-801 water treatment decolorizing agent include:
Dilute KR-801 water treatment decolorizing agent with 10 to 40 times water, then directly add it to the wastewater, stir for a few minutes, and then let it stand or perform air flotation to obtain a clear liquid after decolorization.
Adjusting the pH value of wastewater to 7 to 10 can improve treatment efficiency.
When the color and CODCr value of wastewater are high, in order to save treatment costs, KR-801 water treatment decolorizing agent 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.
