Water Soluble Dicyandiamide Formaldehyde Paper Wastewater Color Remvoal Chemicals

Paper Chemicals Dicyandiamide Formaldehyde Flocculant Used for Wastewater Color Remvoal

 
Description

1. Dicyandiamide Formaldehyde Flocculant is polycationic copolymer flocculant used for decoloring-clarification of sewage and high-colority wastewater from textile dyeing mills, dye-works mills and paper mills.
2. 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.
3. Can 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.
4. Being a positively charged cationic flocculating agent, the flocculant neutralizes the negatively charged pollutants in the wastewater to form insoluble complexes in water. 
5. 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%.

 
Application Fields:

1. Color reducing and COD decreasing for wastewater from textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills, color removal treatment.
2. 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..
3. Used as retention agent in the production process, such as K97.

Competitive Advantage

Application Methods

 
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 30kg, 50kgs, 250kg, 1250kg , or others according to the requirements of clients.
3. The product would show slightly stratification or appear white at low temperature. There is no negative impact on the performance after mixing up.

Application Case

A. When have biological treatment first and after they make chemical treatment.
    In this case they use:
    50-80 ppm BWD-01/03(raw)
    15-20ppm Polyaluminum Chloride(solid)
    1 - 2 ppm Anionic polyacrylamide(solid)
 
    First we apply the PAC (contact time 3-5 min with the waste water), after then BWD-01 Water Decoloring Agent (contact time 5-10 min), and after then anionic polyacrylamide.
    It will give too much economy if we'll adjust the pH 7-8, otherwise the consumption of BWD-01 will be ~20% higher.
