Our BWD-01 Water Decoloring Agent is used for Textile Waste Water Color Removal.
BWD-01 Water Decoloring Agent is a quaternary cationic polymer which is the special product for de-coloring, flocculating, CODcr decreasing and other applications.
Features:
- Stronger decolorization (50%~99%) and removal of COD & BOD( 50%~80%).
- Used to de-color high-colority effluent from dyestuffs plants. High performance to treat wastewater with Reactive, Acid, Disperse, Direct Dyestuff etc. (Soluble and Insoluble dyestuffs).
- Used to treat wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry.
- Used as retention agent in the paper & pulp processing.
- Faster sedimentation, better flocculation.
- Non-pollution(no aluminum, chlorine, heavy metal ions etc.).
- It can be used before or after biological treatment.
- Less sludge produced than other inorganic coagulants.

Usage:
A) Dilutes with 10 - 40 times water and then dosed into the waste water Directly, after being mixed for several minutes, waste is precipitated orAir-floated and the water become clear
B) pH index of the waste water should be adjusted to 7 - 10 for better Result
C) If colority and COD are relatively high, it can be used with the help ofPolyaluminum chloride to reduce treatment cost, whether polyaluminum Chloride is used before or afterwards depends on the flocculation test And the treatment process

Frequently Asked Questions
Q1: May I get one free sample before placing order?
Re: Yes, Sample are available. For small samples is free and you just need to bear the freight;
Q2: Which payment is available for your company?
Re: T/T, L/C or D/P. You can choose the one which is convenient for you.
Q3: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier within 2 days(DHL, FedEx, TNT etc.)

Re: We always believe honesty and responsibility are basis of one company, so whatever products we provide for you all are qualified. We will have goods tested and provide COA before delivery for sure.
Application technical information in Europe
The dyehouses are divided in 2 categories:
A. When they have biological treatment first and after they make chemical treatment. In this case they use:
70-80 ppm BWD-01
15-20 ppm Polyaluminum Chloride
1-2 ppm Anionic polyacrylamide
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
10-20 ppm PAC
1-2 ppm Anionic polyacrylamide
Jar test process for BWD-01
1. Make solution of BWD-01, mix with 40 times water to have 2.5% solution for use.
2. Make PAC solution, 1-3% Al2O3
3. Have solution of anionic Polyelectrolyte, 0.1%.
4. Have effluent, test pH value, adjust pH value to 8-9.(It is very important, higher or lower pH, BWD-01 works not well)
5. Add PAC solution, mix with effluent completely. about 1-3 minutes
6. Add BWD-01 solution, mix with effluent completely, about 5-10 minutes
7. Add small content of anionic polyelectrolyte solution, mix slowly to have big floc.
8. Sedimentation
9. Check color for treated effluent
10. Adjust dosage of BWD-01 and PAC to do more test to have better testing result
