This is Color Removal Chemical which is a special product of decolorizing coagulant, developed with more than 10 years, with very good stability.
Lots of textile mills are using ferrous sulphate and lime for textile effluent treatment, our color removal chemical can replace it, much higher efficiency, low dosage, and low volume sludge.
It is a quaternary ammonium cationic polymer with medium molecular weight polymeric, has high color removal of dye wastewater.
It is a special product for de-coloring, flocculating, CODcr decreasing and other application
It is used to remove the color of wastewater generated by textiles process houses and dyes industries and other fields.
The colored effluents, generated by the industries, when left untreated, play havoc with reusable water resources. For process houses, in water scarce areas, it comes as heaven-sent facilitating recycling of the industrial effluent into process water. Our color removal chemical is to solve this problem.
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.
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 bacteria

Application Fields:

Color removal chemical is mainly used as decolorant for color removal treatment for high-colority effluent from textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills.
It is a good performance to treat wastewater with different dyes, especially the water-soluble dyes as Reactive dye, Acid dye, Disperse dye, Direct dye, Sulphur dye, Vat dye etc..
used in the production process of paper & pulp as a retention agent.

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	Faster sedimentation, better flocculation.
6	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, settling
8	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 adjust the pH of the effluent to 7-9
2	First, we apply the PAC (contact time 3-5 min with the wastewater), 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)
