This Color Removal Chemical is our BWD-01 Water Decoloring Agent, it is a new type of high efficient decolorizing coagulant, developed with more than 10 years, with very good stability.
|Appearance:||Colorless to yellowish translucid liquid|
|Specific Gravity at 20°C:||1.1-1.3|
|PH Value:||3-6 (30% Solution)|
|Solubility:||Soluble With Water at Any Rate|
|Package:||30kgs net plastic drum, 250kgs net plastic drum palletized, 1250kgs net IBC drum|
|Storage Temperature:||Room temperature(10-35℃)|
It has stronger decolorization (50%~99%) and removal of COD (50%~80%).
Used to de-color high-colority effluent from textile and dyestuffs mills.
High performance to treat wastewater with soluble and insoluble dyestuffs, such as Reactive, Acid, Disperse, Direct Dyestuff etc..
Especially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry, and paper industry.
Used as a retention agent in the paper & pulp processing
Faster sedimentation, better flocculation.
Non-pollution (no aluminum, chlorine, heavy metal ions etc.).
It can be used before or after biological treatment.
Less sludge produced than other inorganic coagulants.
Make a solution of Color Removal Chemical, mix with 40 times water to have 2.5% solution for use.
Make a solution of polyaluminium chloride(PAC), with 2-5% Al2O3
Have a solution of Polyacrylamide (Polyelectrolyte), 0.1%.
Have effluent and adjust pH value to 8-10.
Dose PAC solution, mix with effluent completely. about 1-3 minutes
Add BWD-01 solution, mix with effluent completely, about 5-10 minutes
Dose 1-2ppm anionic polyelectrolyte, mix slowly to have big floc, Sedimentation
Check color for treated effluent
Adjust dosage of color removal chemical and PAC to do more test to have a better testing result.
A. When have biological treatment first and after they make chemical treatment.
B. When the treat first by chemicals, then the usual dosages are:
Test and adjustment the pH of the effluent to 7-9
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.
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.
