Description:
Application Fields:
Competitive Advantage:
1 | It has stronger decolorization (50%~99%) and removal of COD (50%~80%). |
2 | Used to de-color 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 | Especially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry, and paper industry. |
5 | Used as a retention agent in the paper & pulp processing |
6 | Faster sedimentation, better flocculation. |
7 | Non-pollution (no aluminum, chlorine, heavy metal ions etc.). |
8 | It can be used before or after biological treatment. |
9 | 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, Sedimentation |
8 | Check color for treated effluent |
9 | Adjust dosage of color removal chemical and PAC to do more test to have a better testing result. |
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 adjustment the pH of the effluent to 7-9 | |
2 | First we apply the PAC (contact time 3-5 min with the waste water), 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. | |
Dosage: | ||
50-80 ppm Color Removal Chemical (raw) | 80-100 ppm Color Removal Chemical (raw) | |
15-20ppm Polyaluminum Chloride (solid) | 15 -30 ppm PAC(solid) | |
1 - 2 ppm Anionic Polyacrylamide (solid) | 1 - 2 ppm Anionic Polyacrylamide(solid) |
