Waste Water Decolouring Agent COD Removal Chemical Auxiliary Agent
Washing Mineral Processing
Brief Description:
Water decoloring agent is dicyandiamide formaldehyde resin and has
high color removal of dye wastewater, by providing a large number
of cations, the negative charge is brought on dye molecules are
neutralized instability, at the same time with CW-08 Water
Decoloring Agent by a large number of hydrolysis of flocs. Can be
adsorbed dye, destabilization of the snare, from water separation,
so as to achieve the purpose of bleaching.
Usage:
- Water Decoloring Agent is mainly used for color removal treatment
for high-colority waste water from dyestuffs plants. It is suitable
to treat waste water with activated, acidic and disperse dyestuffs.
- Water Decoloring Agent can also be used to treat waste water from
textile industry and dye houses, pigment industry, printing ink
industry and paper industry.
- Water Decoloring Agent also can be used in the production process
of paper&pulp as retention agent.
Water Decoloring Agent should 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; The pH value of the waste water should be adjusted to
7-10 for better result. When the colority and COD are relatively
high, Water Decoloring Agent can be used with the help of poly
aluminum chloride, but not mixed together. In this way, the
treatment cost can be lowered.
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.
Package and Storage:
1 It is harmless, non-flammable and non-explosive, it can not be
placed in the sun.
2 It is packed in plastic drums with each containing 30kg, 50kg,

requirements.
3 This product will appear layer after a long-term storage, but the
effect will not be affected with stir. Storage temperature: 5-30°C
Advantage:
1. Strong decolorization
2. It can remove COD better(about 60%)
3. Faster sedimentation, better flocculation
4. Non-pollution(no aluminum, chlorine, heavy metal ions ect.)
