Description:
BWD-01 Water Decoloring Agent is polycationic floccuiating agent (liquid type) consisting of dicyandiamide formaldehyde resin, and can be used for decoloring-clarification of sewage and colored waste water from factories including textile dyeing, dye-works and paper mill. Being a positively charged cationic flocculating agent, BWD-01 neutralizes the negatively charged pollutants in the waste water to form insoluble complexes in water. dicyandiamide formaldehyde resin will offer further flocculating effect, if jointly used with the inorganic flocculating agents including aluminum sulfate, poly-aluminum chloride and ferric chloride, or the polymer group such as polyacrylamide and acryiic polymer. The experimental results indicate that the dicyandiamide formaldehyde resin not only on hydrophobic dispersed dye color removal effect is excellent and of hydrophilic dye (reactive dyes, acid dyes) in addition to the effect of color is also very good, the dyeing wastewater showed that, less dosage, in addition to the obvious, settling velocity and the processing liquid high clarity, while also reducing COD components, improve the removal rate of COD, COD removal rate can reach to more than 98%. It is specially working high performance with the dyeing wastewater containing the hydrophilic dyes (reactive dyes, acid dyes, disperse dyes etc.), less dosage, the color clear, fast speed, high processing liquid clarification of the settlement, but also reduce the composition of COD, improve the COD removal rate.Application Fields:
Can be used for wastewater color treatment for textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills, color removal treatment. Especially high efficient for treating textile wastewater with different dyes, especially the water soluble dyes as Reactive dye, Acid dye, Disperse dye, Direct dye, Sulphur dye, Vat dye etc.. In paper & pulp making industry, it can be used as retention agent in the production process.
Competitive Advantage:
|
1 |
Dicyandiamide formaldehyde resin(BWD-01 Water Decoloring Agent) has strong decreasing of COD and decolorization |
|
2 |
Has functions of de-color high-colority effluent from textile and dyestuffs mills. |
|
3 |
High performance to treat wastewater with soluble and insoluble dyestuffs, such as Reactive, Acid, Disperse, Direct Dyestuff etc.. |
|
4 |
Specially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry. |
|
5 |
Fast sedimentation, better flocculation. |
|
6 |
Less sludge produced than other inorganic coagulants. |
| 7 |
Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun. |
Application Methods:
|
1 |
Mix it with water 40-50 times, dilute the solution, and then the dose it directly in the sewage, with a glass rod to stir a few minutes after sedimentation or flotation can cause the effluent decolorization obtained after the clear liquid. |
| 2 | Adjust the effluent sample pH value to 8-10, that can better improve the decolorization effect of dicyandiamide formaldehyde resin. |
|
3 |
When dyeing and other need to deal with the high chroma of wastewater, COD can and of polym |
