50% Solid Content Dicyandiamide Formaldehyde Resin for Textile Wastewater Treatment

 

Description:

  1. Dicyandiamide Formaldehyde Resin, it is our BWD-01 WATER DECOLORING AGENT, which is a color removal chemical, it is a special flocculant with high efficient for textile effluent color treatment, low dosage, and low volume sludge.
  2. Dicyandiamide Formaldehyde Resin is a cationic copolymer of quaternary, with characters of de-coloring, flocculating, CODcr decreasing and other application
  3. It is used to remove color of wastewater generated by textiles process houses and dyes industries and other fields.
  4. It is specially working high performance with the dyeing wastewater containing the hydrophilic dyes (reactive dyes, acid dyes, disperse dyes, etc.), less dosage, the color clear, fast speed, high processing liquid clarification of the settlement, but also reduce the composition of COD, improve the COD removal rate.
  5. It can be used before or after the biochemical treatment, suggested to dose after the biochemical treatment, can be with low consumption, and low effect to the bacterias.

Specifications:

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

 


Application Fields:

  1. As a special coagulant, Dicyandiamide Formaldehyde Resin is mainly used for color removal treatment for wastewater from textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills.
  2. It is good performance to treat waste water with different dyes, especially the water soluble dyes as Reactive dye, Acid dye, Disperse dye, Direct dye, Sulphur dye, Vat dye etc..
  3. KEMIRA buy from us used in the production process of paper & pulp as retention agent.

Competitive Advantage:

1 Dicyandiamide Formaldehyde Resin is specially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry.

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.


Application Methods:

1 You'd better to prepare effluent sample in beaker first.
2 Test effluent PH, and adjust to 8-10, will let Dicyandiamide Formaldehyde Resin works well.

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.


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:

50-80ppm 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)
