Decolorizing Agent for Textile Wastewater Treatment

This product is a strong cationic quaternary ammonium salt polymer color removal flocculant, easy to dissolve in water, safe, non-toxic, good hydrolysis stability, PH change is not sensitive, has anti-chlorine.The freezing point is about -2.8℃, the specific gravity is about 1.04 GCM, and the decomposition temperature is 280-300℃.This product not only to the hydrophobic disperse dye decolorization effect is excellent, but also to the hydrophilic dye decolorization effect is also excellent, the amount is small, decolorization is obvious, the settling speed is fast, the processing liquid clarity is high, but also to reduce the COD composition, improve the COD removal rate.

Application & Advantages

• Stronger decolorization (50%~99%) and removal of COD & BOD( 50%~80%).
• Used to de-color high-colority effluent from dyestuffs plants. High performance to treat wastewater with Reactive, Acid, Disperse, Direct Dyestuff etc. (Soluble and Insoluble dyestuffs).
• Used to treat wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry.
• Used as retention agent in the paper & pulp processing.
• Faster sedimentation, better flocculation.
• Non-pollution( no aluminum, chlorine, heavy metal ions etc. ).
• It can be used before or after biological treatment.
• Less sludge produced than other inorganic coagulants.

Application method and notes:

1. When the colority and CODcr are relatively high, it can be used with the help of Polyaluminum Chloride, but not mixed together. In this way, the treatment cost can be lower. Whether polyaluminum chloride is used earlier or afterwards depends on the flocculation test and the treatment process.

2. The pH value of the waste water should be adjusted to 7~8 for better result.
3. The product shall be diluted with 10-40 times water and then dosed into the waste water directly. After being mixed for several minutes, it can be precipitated or air-floated to become clear water.
