Decolorizing flocculant
Effluent Decolorizing Focculent is used for effective removal of colors for waste water produced in dyestuff plants. Cationic by nature, offered flocculent promotes sediment formation of suspended color and solids from handled waste water. Offered flocculent is also effective in supporting chemical oxygen demand of treated waste water. Its dosage depends on the quantity of treated effluent. Available in liquid form, effluent decolorizing flocculent is non toxic by composition and it readily dissolves in water. Before its application, ph value of waste water needs to be adjusted to get the desired result.

1. Decolorizing flocculant is easily dissolved in water, can form a multi-nuclear complex to make the water particles colloids, particulate suspended matter polymerization together grow up, to form a large volume, high density, fast settling flocculant;
2. In water treatment, decolorizing flocculant for raw water ph wide range (ph7-10), the most suitable for slightly alkaline;
3. The decolorizing flocculant has no corrosive effect on pipeline equipment, and the removal rate of chroma, ss, cod and bod of sewage is high, and the treated wastewater can meet the national discharge standards;
4. Decolorizing flocculant no suspended solids or sediment, will not block dosing equipment and pipelines, for wastewater treatment can be directly added to the original solution, no secondary pollution;
5. Decolorizing flocculants produce flocculant density, less sludge.
Advantages of decolorizing flocculants
Stronger decolorization rate (50%~99%) and COD, BOD removal rate (50%~80%).
Used for decolorization of high-chromaticity wastewater from dye plants. Highly efficient treatment of wastewater from reactive dyes, acid dyes, disperse dyes, direct dyes, etc. (soluble dyes and insoluble dyes).
Used for treating wastewater from textile printing and dyeing industry, pigment industry, ink industry, and papermaking industry.
Used as a retaining agent in paper and pulp processing.
Faster sedimentation rate and better flocculation effect.
No pollution (does not contain aluminum, chlorine, heavy metal ions, etc.).
Can be used before or after biological treatment.
Produces less sludge than other inorganic coagulants.
Scope of application
It is mainly used for decolorization of high chroma wastewater from dye plants, and can be applied to wastewater treatment of reactive, acidic and Disperse dye.
Bleaching agents can also be used for the treatment of textile and printing wastewater, as well as for the treatment of industrial wastewater such as pigments, inks, and papermaking.
This product can also be used as a reinforcing agent, sizing agent, and charge neutralizer for papermaking. The use of decolorizing agent is very similar to that of Aluminium chlorohydrate, which is added after dissolution. When small flocs appear in the water, polyacrylamide is used to aid coagulation and separation. Decolorizing agent can be used alone or together with Aluminium chlorohydrate, because of the synergistic effect of different agents, it has better water purification effect. Due to the delamination of decolorizing agents below 0 ° C, it is best to store at a temperature above 0 ° C. If layering occurs, stir evenly and dissolve before use, without affecting the effect.
This product can be used as a decolorizing agent for printing and dyeing wastewater, leather wastewater, slaughterhouse wastewater, papermaking wastewater, papermaking anionic waste catcher, and so on.
Usage and Precautions
1. Dilute the product with 10-50 times of water, and then directly add to the water, stir for a few minutes after settlement or air flotation, you can get the decolorized clear liquid;
2. The ph value of wastewater adjusted to 7-10 can improve the treatment effect;
3. When the color and cod of the wastewater is high, it can be used with polyaluminum chloride, but it can not be mixed. In this way, the treatment cost can be reduced, and whether to add polyaluminum chloride first or later should be determined according to the test and treatment process.
Decolorizing Flocculant Production Process
During the preparation process of the dicyandiamide-formaldehyde polycondensate decolorizing flocculant, the raw materials must be heated to initiate the condensation reaction. The preparation method of the present invention is: Adding dicyandiamide, formaldehyde, and ammonium chloride into the reaction kettle in proportion to mix them, and then adding a certain amount of calcium chloride, and using the heat released when calcium chloride is dissolved in water to make the reaction kettle The raw material temperature rises locally at the bottom, thereby initiating the condensation reaction of dicyandiamide-formaldehyde. Adopting the present invention to prepare the decolorizing agent saves external heat source heating, reduces energy consumption, saves equipment investment costs, and reduces the chance of bumping; The addition of calcium ions accelerates the settling speed of the formed flocs and enhances coagulation Efficiency improves the performance of the product and creates favorable conditions for the wider use of decolorizers in the field of water treatment. The decolorizing flocculant is mainly used to remove chroma, COD and SS from industrial wastewater such as printing and dyeing, tanning, and papermaking.
