De-Coloring Agent


This product is a Quaternary Cationic Polymer is used to treat effluent for color removal, flocculating and COD decreasing in Paper, Textile and Dyeing industries, etc. It has a great decoloring capacity and can be applied in very low doses to get desired decoloring effect. Various grades are available for different types of coloured industrial water.


It is mainly used for color removal of dense color waste water from dyestuffs plants. It is suitable to treat waste water with activated, acidic and disperse dyestuffs.
It can also be used to treat waste water from paper industry, textile industry and dye houses, pigment industry, printing ink industry.
It can also be used in the production process of paper and pulp as retention agent.
It can be applied at very low doses (substoichiometric levels) thus being very economical in nature.


Physical State: Light color, sticky liquid.
Viscosity: 50-300 m Pa. S (20º C)
Solid content: 50% min.
pH 30% solution: 2 – 5
Specific Gravity: 1.1 – 1.3 (25º C)

Application Method

The product shall be diluted with 10-40 times water and then dosed into the waste water directly. After being mixed for several minutes, waste can be precipitated or air-floated and the water becomes clear.
The pH index of the waste water should be adjusted to 7-10 for better result.
When the color and COD are relatively high, it can be used with the help of polyaluminum chloride to reduce treatment cost. Whether polyaluminum chloride is used before or afterwards depends on the flocculation test and the treatment process.

Package & Storage

It is harmless, no-flammable and non-explosive, can be stored at room temperature range of 10-30ºC, and should not be placed in the sun.
It is packed in plastic drums with each containing 30kg, 250kg, and 1250 kg.
