1

BWD-01 Water Decoloring Agent has strong decolorization and decreasing of COD.

2

Used to de-color high-coloring 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

Used as a retention agent in the paper & pulp processing

6

Faster sedimentation, better flocculation.

7

Less sludge produced than other inorganic coagulants.

Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun.

1

Mix BWD-01 Water Decoloring Agent with water 40-50 times, dilute the solution, and then the dosage it directly in the sewage, with a glass rod to stir a few minutes after sedimentation or flotation can cause the effluent decolorization obtained after the clear liquid.

3

When dyeing and other need to deal with the high chroma of wastewater, COD can and of polymer aluminum chloride (PAC) with the use, but attention not mixed-use. This can effectively reduce the wastewater decolorization processing cost, how to add PAC should be according to the actual situation, it is best to make the professional and technical personnel to develop a good solution.

8

Add small content of anionic polyelectrolyte solution, mix slowly to have big floc, Sedimentation.

9

Check color for treated effluent

A. When they 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 8-10

2

First, we apply the PAC (contact time 3-5 min with the wastewater), after then BWD-01 Water Decoloring Agent (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.
