KR-801 Water Decoloring Agent

CAS No. 55295-98-2 EINECS No. 686-887-0
Molecular Formula C3H8ClN5O Molecular Weight 165.58
Structural Formula

Product Features

KR-801 Water Decoloring Agent is a cyanoguanidine series cationic polymer compound, which has various functions such as decolorization, flocculation, and CODcr degradation. It is mainly used for the treatment of high-concentration and high-color wastewater of dyes, printing & dyeing and intermediate process, especially for active, acidic and disperse dyes’ wastewater treatment.

KR-801 Water Decoloring Agent can be used for the treatment of industrial wastewater such as textile, printing and dyeing, medicine, papermaking, chemical industry, etc., with decolorization rate >95% and CODcr removal rate >65%.

Remark: Solid content could be specially produced according to demand.

Applications & Usage

1. Dilute KR-801 Water Decoloring Agent with 10~40 times of water, then add it directly to wastewater, stir for a few minutes then settle or air flotation to obtain the decolorized clear liquid.

2. Adjust the pH value of wastewater to 7~10 can improve the treatment performance.

3. When the color and CODCr of the wastewater are high, to save treatment cost, KR-801 Water Decoloring Agent can be used intermittently with polyaluminium chloride(PAC), while KR-801 and PAC could not mixed together. Whether to add polyaluminium chloride first or then should be determined according to lab test and treatment process.
