Product Description:
Product Name: BWD-01 Water Decoloring Agent
Component: Dicyandiamide-formaldehyde Resin
Solid Content: 50%min
HS CODE: 391190/391400
Application:
wastewater treatment in the paint industry, industrial wastewater treatment, flocculation water treatment, water clarifying agent, water purifying agents, decolouring agent, cationic polymers water treatment
BWD-01 Water Decoloring Agent is a high-performance color removal chemical.
The mechanism is by providing a large number of cations, the negative charge is brought on dye molecules are neutralized instability, at the same time with BWD-01 Water Decoloring Agent by a large number of hydrolysis of flocs. Can be adsorbed dye, destabilization of the snare, from water separation, so as to achieve the purpose of bleaching.
Specifications:
Appearance: | Colorless liquid |
Solid Content: | 50%min |
Specific Gravity at 20°C: | 1.2-1.3 |
PH Value (30% Solution): | 3-6 |
Shelf Life: | 12months |
Application Methods:
1 | Make BWD-01 solution, and mix with 40 times water to have 2.5% solution for use. |
2 | Make PAC solution, 5% Al2O3 |
3 | Prepare Polyelectrolyte solution, 0.1%. |
4 | Prepare the effluent, test pH value, and adjust pH value to 8-9. (It is very important, higher or lower pH, BWD-01 works not well) |
5 | Add PAC solution, and mix with effluent completely. about 1-3 minutes |
6 | Add BWD-01 solution, and mix with effluent completely, about 5-10 minutes |
7 | Add small content of anionic polyelectrolyte solution, and mix slowly to have a big floc. (this step is a suggestion) |
8 | Sedimentation |
9 | Check the color for treated effluent |
10 | Adjust the dosage of BWD-01 and PAC to do more tests to have a better testing result. |
Advantages:
Liquid type easy to use, non-toxic, not corrosive |
High-efficient decolorization for different dye effluent color treatment |
High color removal of more than 98% |
Low dosage, low sludge than traditional Alum and Iron coagulants. |
