50% Solid Content Dicyandiamide Formaldehyde Resin for Textile Wastewater Treatment

Appearance:

Colorless to yellowish translucid liquid

Solid Content:

≥50%

Specific Gravity at 20°C:

1.1-1.3

PH Value:

3-6 (30% Solution)

Package:

30kgs net plastic drum, 250kgs net plastic drum palletized, 1250kgs net IBC drum

2

Very high decolorization rate of 50~99%, and decreasing of COD with 50~80%.

3

Used to treat high-colority effluent from textile and dyestuffs mills.

4

High performance to treat wastewater with soluble and insoluble dyestuffs, such as Reactive, Acid, Disperse, Direct Dyestuff etc..

6

Faster sedimentation, better flocculation, low dosage and cost.

7

Less sludge produced than other inorganic coagulants.

3

Make solution of Dicyandiamide Formaldehyde Resin, mix with 40 times water to have 2.5% solution for use.

4

Make solution of polyaluminium chloride(PAC), with 2-5% Al2O3

5

Have solution of Polyacrylamide (Polyelectrolyte), 0.1%.

6

Have effluent and adjust pH value to 8-10.

7

Dose PAC solution, mix with effluent completely. about 1-3 minutes

8

Add BWD-01 solution, mix with effluent completely, about 5-10 minutes

9

Dose 1-2ppm polyelectrolyte, mix slowly to have big floc, settling

10

Check color for treated effluent, and calculate the dosage.

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:

50-80ppm Dicyandiamide Formaldehyde Resin (raw)

80-100ppm Dicyandiamide Formaldehyde Resin(raw)

15-20ppm Polyaluminum Chloride (solid)

15 -30 ppm PAC(solid)

1 - 2 ppm Polyacrylamide (solid)

1 - 2 ppm Polyacrylamide(solid)
