Package: |
30kgs net plastic drum, 250kgs net plastic drum palletized, 1250kgs net IBC drum |
Application Fields:
Competitive Advantage:
1 |
Very high decolorization rate of 50~99%, and decreasing of COD with 50~80%. |
2 |
Used to treat 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 |
Faster sedimentation, better flocculation. |
6 |
Less sludge produced than other inorganic coagulants. |
Application Methods:
1 |
Make a solution of Color Removal Chemical, mix with 40 times water to have 2.5% solution for use. |
2 |
Make a solution of polyaluminium chloride(PAC), with 2-5% Al2O3 |
3 |
Have a solution of Polyacrylamide (Polyelectrolyte), 0.1%. |
4 |
Have effluent and adjust pH value to 8-10. |
5 |
Dose PAC solution, mix with effluent completely. about 1-3 minutes |
6 |
Add BWD-01 solution, mix with effluent completely, about 5-10 minutes |
7 |
Dose 1-2ppm anionic polyelectrolyte, mix slowly to have big floc, settling |
8 |
Check color for treated effluent, and calculate the dosage. |
Application Case:
A. When have biological treatment first and after they make chemical treatment. |
B. When the treat first by chemicals, then the usual dosages are: |
|
1 |
Test and adjust the pH of the effluent to 7-9 |
|
2 |
First, we apply the PAC (contact time 3-5 min with the wastewater), after then Color Removal Chemical (contact time 5-10 min), and after then anionic polyacrylamide. |
|
3 |
It will give too much economy if we'll adjust the pH 7-9, otherwise, the consumption of color removal chemical will be ~20% higher. |
