Water Decoloring Agent PolyDCD for Textile Wastewater Treatment

CAS Number: 55295-98-2

Trade name: LSD-01 / LSD-03 / LSD-07 Decoloring Agent

Chemical name: PolyDCD; Dicyandiamide formaldehyde resin

Water Decoloring Agent is a quaternary ammonium cationic copolymer, specifically dicyandiamide formaldehyde resin. It offers excellent efficiency in decoloring, flocculating and COD removal.

• Primarily used to decolor effluent with high colority from dyestuff plants, suitable for treating wastewater with activated, acidic and disperse dyestuffs
• Effective for wastewater treatment in textile industry, dye houses, pigment industry, printing ink industry and paper industry
• Can be used in paper & pulp production as retention agent

Concentration and viscosity of solution can be customized according to customers' needs.

• Dilute with 10-40 times water before adding to wastewater. After stirring, clear water can be obtained through precipitation or air-floatation
• Optimal wastewater pH range: 6-10
• Recommended to use with inorganic flocculants for high color/COD effluent to reduce operation costs. Dosage order and proportion should be determined by flocculation tests
• May show layer separation and become white at low temperature, but this doesn't affect performance after mixing

• Store in dry, ventilated room at 5-30℃
• Available in 250kg/drum or 1250kg/IBC packaging
• Shelf life: 12 months
