    Dicyandiamide Formaldehyde Polycationic Flocculation Water Decoloring Chemicals




    1. 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.
    2. Being a positively charged cationic flocculating agent, BWD-01 neutralizes the negatively charged pollutants in the waste water to form insoluble complexes in water.
    3. 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.
    4. 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%.
    5. 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:

    1. Can be used for wastewater color treatment for textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills, color removal treatment.
    2. 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..
    3. In paper & pulp making industry, it can be used as retention agent in the production process.

    Product Name:

    Dicyandiamide Formaldehyde Resin
    (BWD-01 Water Decoloringi Agent)


    White or light yellow aqueous solution

    Solid Content:     


    Specific Gravity :

    Not less than 1.20 g/ml (at 25゚C)

    PH Value:

    3-6 (@30% Solution)


    50-300cps (@25°C)


    30kgs net plastic drum, 250kgs net plastic drum palletized, 1250kgs net IBC drum


    Application Methods:


    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.


    When dyeing and other need to deal with the high chroma of wastewater, COD can and of polymer aluminum chloride (PAC) with the use, but attention not mixed use. This can effectively reduce the waste water decolorization processing cost, how to add PAC should be according to the actual situation, it is best to make the professional and technical personnel to develop a good solution.


    Add small content of anionic polyelectrolyte solution, mix slowly to have big floc, Sedimentation.

    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.

    Dicyandiamide Formaldehyde Polycationic Flocculation Water Decoloring Chemicals
    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.
    B. When the treat first by chemicals, then the usual dosages are :
        Adjustment the pH 7-8
        80-100 ppm BWD-01/03(raw)
        15 -30 ppm PAC(solid)
        1 - 2 ppm Anionic polyacrylamide(solid)
