water decoloring reagent

Main Components:

    Cyanoguanidine Polymer

Application Fields:

• Mainly used for color removal treatment for high-colority effluent from textile dyeing & printing mills, dyestuffs & pigment mills, ink & paper making mills.
• Suitable to treat waste water with Reactive dye, Acid dye, Disperse dye, Direct dye, Sulphur dye, Vat dye etc..
• Can be used in the production process of paper & pulp as retention agent.

Advantages:

• Stronger decolorization ( 50%~90%) and removal of COD & BOD( 80%~99.9%)
• Faster sedimentation, better flocculation, fewer sludge.
• Non-pollution(no aluminum, chlorine, heavy metal ions etc.)

Note:We can produce according to customers different s.

Package & Storage:

• It is harmless, no-flammable and non-explosive, it can be stored at room temperature, it can not be placed in the sun.
• It is packaged in plastic drums with each containing 30kg, 250kg, 1250kg , or others according to the requirements of clients.
• Storage temperature: 5-30C.
• The product would show slightly stratification or appear white at low temperature. There is no negative impact on the performance after mixing up.

Application Method:

• Make solution of BWD-01, mix with 40 times water to have 2.5% solution for use.
• Make PAC solution, 1-3% Al2O3
• Have solution of anionic Polyelectrolyte, 0.1%.
• Have effluent, test pH value, adjust pH value to 8-9.(It is very important, higher or lower pH, BWD-01 works not well)
• Add PAC solution, mix with effluent completely. about 1-3 minutes
• Add BWD-01 solution, mix with effluent completely, about 5-10 minutes
• Add small content of anionic polyelectrolyte solution, mix slowly to have big floc. (this step is suggestion)
• Sedimentation
• Check color for treated effluent
• Adjust dosage of BWD-01 and PAC to do more test to have better testing result.
