What is BL-19TS Water Decolorant Agent?
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 a heaven-sent facilitating recycling of the industrial effluent into process water. BL-19TS Water Decoloring Agent is used to solve this problem.
1. BL-19TS Water Decoloring Agent is a new type of high efficient decolorizing flocculant, published in 90's, and developed with more than 10 years, with very good stability.
2. It has high color removal of dye wastewater, by providing a large number of cations, the negative charge is brought on dye molecules are neutralized instability, at the same time with BL-19TS Water Decoloring Agent by a large number of hydrolysis of flocs. Can be adsorbed dye, destabilization of the snare, from water separation, so as to achieve the purpose of bleaching.
3. It is a color removal chemical, special product for de-coloring, flocculating, CODcr decreasing and other applications.
4. It is used to remove color of waste water generated by textiles process houses and dyes industries and other fields.
5. Bl-19TS Water Decoloring Agent 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.
6. 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.
7. To reduce the costs of color wastewater treatment, suggested to use polyaluminium chloride together, can reduce the dosage of Bl-19TS Water Decoloring Agent.
8. In paper making, BL-19TS Water Decoloring Agent also can be used as fixing agent in the paper processing, will be very good performance.
9. 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. It is slightly acidic, when skin contact, wash immediately with plenty of water.
What is BL-19TS Water Decolorant Agent Used for?
1. Mainly used for Color Removal and COD Reduction for wastewater from textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills.
2. Suitable to treat waste water with Reactive dye, Acid dye, Disperse dye, Direct dye, Sulphur dye, Vat dye etc..
3. Can be used in the production process of Paper & Pulp as Retention Agent.
What is the Advantage of BL-19TS?
1. Strong decolorization ( 80%~99%) and removal of COD ( 50%~80%)
2. Faster sedimentation, better flocculation, fewer sludge.
3. Non-pollution(no aluminum, chlorine, heavy metal ions etc..).

Direction For Use
1.Make solution of BL-19TS, 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, BL-19TS works not well)
5.Add PAC solution, mix with effluent completely. about 1-3 minutes
6.Add BL-19TS solution, mix with effluent completely, about 5-10 minutes
7.Add small content of anionic polyelectrolyte solution, mix slowly to have big floc. (this step is suggestion)
8.Sedimentation
9.Check color for treated effluent
10.Adjust dosage of BL-19TS and PAC to do more test to have better testing result.
Product Application
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 8-9
2.First we apply the PAC (contact time 3-5 min with the waste water), after then BL-19TS 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 8-9, otherwise the consumption of BL-19TS will be ~20% higher.
Dosage:
50-80 ppm BL-19TS (raw)
80-100 ppm BL-19TS (raw)
15-20ppm Polyaluminum Chloride(solid)
15 -30 ppm PAC(solid)
1 - 2 ppm Anionic polyacrylamide(solid)
1 - 2 ppm Anionic polyacrylamide(solid)
Package & Storage
1. It is harmless, no-flammable and non-explosive, it can be stored at room temperature, it can not be placed in the sun.
2. It is packaged in plastic drums with each containing 30kg, 50kgs, 250kg, 1250kg , or others according to the requirements of clients.
3. Storage temperature: 5-30°C.
4. The product would show slightly stratification or appear white at low temperature. There is no negative impact on the performance after mixing up.
