wastewater decolorant [papermaking&dye print]

Product introduction

This product is a cationic polymers containing quaternary ammonium salts, which appearance is 

colorless to light yellow viscose liquid, freezing point:-2.8°C,specific weight:1.04 g/cm3, 

resolve temperature 280—300°C.This product not only can decolor the hydrophobic disperse 

dyes effectively, but also to the water affinity dye (reactive dyes, acid dyes). After a test for dye sewage, 

we found that few dosage can decolor obviously, settle quickly and process the fluid transparency 

highly, simultaneously reduce the COD, enhanced the removal of COD.

USE

In order to protect environmental, the colored wastewater must be treated, since the color of 

industrial sewage is dark which discharged from the dyeing chemical factories. This product 

synthesizes decoloration, flocculation and COD dissolution, has evident synthetic effect in decoloration.

The procedure is based on the technology and experiment.

A. Wastewater pretreatment

Adjust pH value to neutrality with the white lime.

B.Solution preparation

1. Start agitation of the inorganic flocculant pot, feed poly( aluminum chloride) to water slowly and completely , then,we can get 5% poly( aluminum chloride) solution.

2. Start agitation of the organic flocculant pot, feed decolorant to water slowly and completely , then we can get 3‰ decolorant solution.

C. decolor treatment

1.Start agitation of wastewater pool at high stirring rate,and feed the poly( aluminum chloride) solution(about 5-15Kg) to the wastewater simultaneously.

2.Lower the stirring rate, and feed decolorant solution above(about 2-10Kg) to the wastewater simultaneously.

3.stir slowly for a period of time.

4. place it at a standstill.

D.Check quality and filter.
