This product is a quaternary ammonium type cationic polymer which is very effective in decoloring, flocculating, COD decreasing.
Our factory produces the wastewater decoloring agents to make the color suside in line with the more strict environmental protection standards.
Main Components:
dicyandiamide formaldehyde resin
Application Field:
1. It is mainly used for waste water treatment for printing, dyeing, textile, mining, ink, paper and so on.
2. It can be 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.
3. It also can be used in the production process of paper & pulp as retention agent.
Advantage:
1.Stronger decolorization(>95%) and removal of COD,BOD(40—70)
2.Faster sedimentation, better flocculation
3.Non-pollution(no aluminum, chlorine, heavy metal ions ect.)
Specifications:
1.Appearance: colorless or light-color liquid
2.Viscosity: 50-250 m Pa.s (20°C)
3.Solid content: >50%
4.pH, 30% solution: 3-5
5.Specific gravity : 1.15-1.25 (25°C)
Application Method:
1. 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.
2. The pH value of the waste water should be adjusted to 4-12 for better result.
3. 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 lowered. Whether polyaluminum chloride is used beforewards or afterwards depends on the flocculation test and the treatment process.
Package and Storage:
1. It is harmless, no-flammable and non-explosive, it can be stored at room temperature, it can not be placed in the sun.
2. It is packaged in plastic drums with each containing 25kg, 200kg, 250kg ,or others according to the requirements of clients.
3. Storage temperature: 5-30°C
Application of CW-06 Water Decoloring Agent
1.Wastewater Treated:
Dyeing wastewater with activated color and dispersing color, it is difficult to be treated by other water treatment products.
2.Treating Process:
Dyeing wastewater treated by biotechnology
Dose CW-06 → Dose PAC → Dose PAM → treated water
3.Application Data
* Dosage of CW -06: 40-100 PPM
Dosage of PAC: 150 PPM
Dosage of PAM: 1 PPM
* Waster water inlet
COD: 600 mg/l
Color: 250-300 times
* Wastewater treated(outlet)
COD: about 100mg/l
Color: 40-50 times
4.Result
a) CW -06 has good color removal and especially to red color, it can treat the wastewater to reach Chinese Standard.
b) In the practice application, apply with PAC and PAM together, it can get better result and it is more economic.
* Chinese color unit is time, it means how many times the water diluted by distilled water to reach no color.
* PAC – poly-aluminum chloride
* PAM – polyacrylamide anionic type
