High purity dicyandiamide formaldehyde polymer is a highly effective water decolorizing agent specifically designed for industrial wastewater treatment. This 50% solid content resin delivers exceptional performance in color removal and COD reduction for various industrial applications.

• Excellent decolorization of printing and dyeing wastewater with strong resistance to chloride
• Effective on both hydrophobic dispersed dyes and hydrophilic dyes including reactive, acid, and disperse dyes
• COD removal rate exceeding 98% with minimal dosage requirements
• Fast sedimentation velocity and high processing liquid clarity
• Can be used alone or in combination with PAC for enhanced performance
• Produces less sludge compared to inorganic coagulants
• Soluble in water, safe, non-toxic, and non-flammable
• Hydrolytic stability with insensitivity to pH value changes

• High-colority effluent from textile dyeing & printing mills
• Dyestuffs & pigment manufacturing facilities
• Ink production and paper making mills
• Wastewater treatment for various soluble dyes including reactive, acid, disperse, direct, sulphur, and vat dyes
• Retention agent in paper & pulp manufacturing processes

Mix with water 40-50 times to dilute, then dose directly into sewage. Stir for several minutes before sedimentation or flotation to achieve clear effluent.

Adjust effluent pH to 7-10 for improved decolorization effect. For high chroma wastewater, combine with PAC (not mixed) to reduce processing costs.
