Chemicals For Decolorization Of Reactive Dye Printing And Dyeing Wastewater Manufacturer Decoloring Agent

Chemicals for Decolorization of reactive dye printing and dyeing wastewater Manufacturer High Quality Decoloring Agent

​Description:
The water decoloring agent, composed of dicyandiamide-formaldehyde resin, effectively removes color from dye wastewater through a dual-action mechanism. As a quaternary ammonium cationic copolymer, it releases abundant cations that neutralize the negative charges on dye molecules, destabilizing their colloidal structure. Simultaneously, its hydrolysis generates large flocculent aggregates (e.g., CW-08 formulation), which adsorb and entrap the destabilized dye particles. This combined process of charge neutralization and flocculation enables efficient separation of dyes from water. The agent demonstrates superior performance in decolorization, floc formation, and chemical oxygen demand (COD) reduction, making it particularly effective for treating complex industrial dye effluents.
 
 
Application: 
1. It is mainly used for removing color from effluents with high color intensity in dye factories, especially those with activated, acidic, and disperse dyestuffs.

2. It can be employed to treat wastewater from industries such as textiles, dye houses, pigment manufacturing, printing ink production, and paper processing.

3. The product is also used as a retention agent in the paper and pulp industry during the production phase.

Instructions for use:

1. The product is to be diluted with 10 to 40 times its volume of water before being added to the wastewater. After stirring for several minutes, clear water will be formed by precipitation or air flotation.

2. The wastewater should be within a pH range of 6 to 10 for best treatment results.

3. Using this product with inorganic flocculants is advised for treating effluents with high color and COD, which helps to reduce operating costs. The dosage and application sequence should be tailored based on flocculation test results and the specific treatment process.

4.When subjected to low temperatures, the product may show signs of layer separation and turn white, but mixing it will ensure there is no adverse impact on its performance.

Concentration and viscosity of solution can be customized according to customers’ needs.
 
Advantage:

The water decoloring agent exhibits strong decolorization efficiency, achieving 85–95% dye removal. It also provides superior COD (Chemical Oxygen Demand) reduction of approximately 60%, along with faster sedimentation and enhanced flocculation performance. Additionally, the agent is environmentally safe, containing no harmful substances such as aluminum, chlorine, or heavy metal ions.

Success Cases:

1. The customer sent a water sample of reactive dye printing and dyeing wastewater (as shown in the picture below).

2. The customer requested decolorization.

3. Reagents used in the experiment -- Decolorizer.

3. Experimental results

After using our decolorizer, large flocs formed and the water quality became significantly clearer. The customer was very satisfied with the decolorization effect and decided to place a large - scale purchase order.

Package and Storage:

Safety & Storage Instructions:

The product is non-toxic, non-flammable, and non-explosive. However, it should be stored away from direct sunlight.
