Color Removal Chemical Dicyandiamide Formaldehyde Resin Type for Water Treatment
Dicyandiamide Formaldehyde Resin
Colorless to Yellowish Translucid Liquid
Specific Gravity at 20°C:
PH Value (30% Solution):
Soluble With Water at Any Rate
30kgs net plastic drum, 250kgs net plastic drum palletized, 1250kgs net IBC drum
Dicyandiamide Resin 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..
Specially used to treat color wastewater from textile and dyeing industry, pigment industry, printing ink industry and paper industry.
Used as 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 solution of Dicyandiamide Resin, mix with 40 times water to have 2.5% solution for use.
Make polyaluminium chloride (PAC) solution, with 2-5% Al2O3
Have solution of Polyacrylamide (Polyelectrolyte), 0.1%.
Have effluent, test pH value, adjust pH value to 7-9.(It is very important, higher or lower pH, BWD-01 works not well)
Dose 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)
Check color for treated effluent
Adjust dosage of BWD-01 and PAC to do more test to have 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 Dicyandiamide Resin (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.
