Dicyandiamide Formaldehyde Polymer for Industrial Wastewater Decolorization

High-efficiency cationic polymer for reactive dyes, pigment wastewater, paper mill effluent, and chemical industry wastewater treatment

Product Overview

Dicyandiamide Formaldehyde Polymer is a high-performance water decolorizing polymer. It is designed to remove color from industrial wastewater containing reactive dyes, acid dyes, disperse dyes, pigment wastewater, and other high-color effluents.

Developed using Dicyandiamide Formaldehyde Resin technology, this polymer works through charge neutralization and bridging flocculation, forming dense, fast-settling flocs for superior color removal. It is widely applied in textile dyeing, paper mills, chemical production, and electroplating wastewater.

Problem in Industrial Wastewater

Industrial wastewater often contains:

  • High color intensity
  • Soluble dye molecules resistant to conventional treatment
  • High COD and low biodegradability
  • Fluctuating wastewater quality

Traditional coagulants like PAC, alum, or ferric salts often fail to remove soluble dyes effectively, leading to residual color, excessive sludge, and difficulty meeting discharge standards.

Why Dicyandiamide Formaldehyde Polymer Works

  • Powerful cationic polymer: quickly reacts with negatively charged dye molecules
  • Charge neutralization: destabilizes dissolved color
  • Flocculation & sedimentation: forms dense flocs for rapid separation
  • Compatible with PAC/PAM systems: integrates with existing coagulation and flocculation processes

Key Advantages

  • 50–99% color removal efficiency
  • Significant COD reduction
  • Faster floc settling and clearer supernatant
  • Reduced chemical dosage
  • Lower sludge volume
  • Stable and reproducible results

Specifications

Applications

  • Textile dyeing wastewater: reactive, acid, disperse dyes
  • Paper & pulp wastewater: improves color clarity
  • Chemical & pigment production wastewater
  • Electroplating & leather wastewater: removes complex color contaminants

Treatment Process Recommendation

  1. Adjust pH to 6.5–7.5
  2. Add Dicyandiamide Formaldehyde Polymer
  3. Add PAC or other coagulant for enhanced flocculation
  4. Add PAM to accelerate settling
  5. Sedimentation or DAF for clear water separation

Jar Test Procedure

  1. Collect real wastewater sample
  2. Rapidly mix in polymer
  3. Add PAC / PAM as required
  4. Slow mixing to form flocs
  5. Observe color removal, COD reduction, and settling rate

How to Choose

  • Match polymer to dye type and wastewater characteristics
  • Use PAC/PAM for high COD or unstable color
  • Pre-adjust pH for optimal floc formation
  • Always perform laboratory jar test to determine optimal dosage

FAQ

Q1: What is the main advantage over PAC alone?

Targets soluble dyes that PAC cannot remove efficiently.

Q2: Can it reduce COD as well as color?

Yes, it reduces color and COD simultaneously.

Q3: How to determine the dosing amount?

Conduct jar tests; typical dosing ranges from 5–50 mg/L depending on water quality.

Q4: Is it compatible with PAC/PAM systems?

Yes, designed for synergy in coagulation and flocculation processes.
