Decolorizing Agent

Decolorizing agent is quaternary ammonium type,dicyandiamide formaldehyde resin based cationic polymer.

Water decoloring agent has high efficiency absorb and fast sedimentation in the anion color particles in the waste water.

Water decoloring agent can neutralize the electric charge and form a good coagulant floc.It also can combine those can coagulate anionic substances dyeing water such as direct,reactive,vat,disperse and acid eyes.

Water decoloring agent is specialized product for decoloring, flocculating, COD decreasing

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.

Our main products include polyaluminum chloride ，Aluminum chlorohydrate，polyferric sulfate，biochemical bacteria，polyacrylamide pam and decoloring agent.
