Application Area

1. Wastewater Treatment in the Dye Industry: Primarily addressing the decolorization needs of colored wastewater from dye production enterprises, it can be adapted to various types of dye wastewater, including reactive dyes, acid dyes, disperse dyes, etc.; especially in the treatment of disperse dye wastewater, its decolorization performance is more prominent.
2. Textile Dyeing and Related Industrial Wastewater: Suitable for purifying mixed wastewater generated during textile dyeing and processing, and can also be extended to industrial wastewater treatment scenarios in areas such as pigment preparation, ink production, and the paper industry.
3. Auxiliary Treatment of High-Suspended Solids Wastewater: For wastewater systems with relatively high suspended solids content, this product can achieve significant sedimentation through flocculation, thereby assisting in reducing the content of solid impurities in the wastewater.
