Water Decoloring Agent – Dicyandiamide Formaldehyde Flocculant (CAS 55295‑98‑2)

High-efficiency polymer for color removal and flocculation in industrial wastewater, textile dyeing, paper mills, and chemical production.

Product Overview

Water Decoloring Agent – Dicyandiamide Formaldehyde Flocculant is a high-efficiency organic polymer developed for advanced color control and flocculation in wastewater treatment systems. It is formulated for high-color industrial wastewater, textile dyeing & printing wastewater, and other complex effluents where conventional coagulants struggle.

The product works through charge neutralization and adsorptive bridging, removing dissolved color and organic load effectively.

Challenges in Wastewater Decolorization

  • High soluble dye concentration
  • Complex organic colorants resistant to conventional treatment
  • High COD and poor biodegradability
  • Fluctuating wastewater quality and color stability

Traditional coagulants such as PAC, alum, or ferric salts typically perform poorly on dissolved dyes, leaving residual color and failing discharge standards.

How This Decoloring Agent Works

  • Charge Neutralization: Positively charged polymer molecules neutralize negatively charged dye colorants and organics.
  • Adsorptive Bridging: Polymer chains bind multiple particles, forming larger, denser flocs.
  • Enhanced Flocculation & Settling: Flocculated solids settle rapidly or can be removed by dissolved air flotation (DAF), resulting in clearer effluent.

Key Benefits

  • Effective color removal – improves effluent clarity even in high-color wastewater
  • COD reduction – lowers chemical oxygen demand
  • Improved flocculation – works synergistically with PAC and PAM
  • Faster settling – denser flocs improve separation efficiency
  • Reduced sludge volume – more efficient solids capture
  • Stable & repeatable performance – suitable for continuous industrial wastewater systems

Typical Applications

  • Textile dyeing & printing wastewater: reactive, acid, disperse dyes, pigment wastewater
  • Industrial effluents: chemical plants, dye manufacturing, electroplating wastewater, leather & fabric finishing

Recommended Treatment Process

  1. Pre-adjust pH to 6.5–8.0
  2. Add Dicyandiamide Formaldehyde Flocculant
  3. Add PAC (Polyaluminum Chloride)
  4. Add PAM (Polyacrylamide) to improve settling
  5. Clarification via sedimentation or DAF

Laboratory Jar Test Procedure

  1. Collect real wastewater sample
  2. Add decoring agent under rapid mixing
  3. Add PAC and PAM as needed
  4. Slow mixing to form floc
  5. Observe floc size, settling rate, and clarity

How To Select & Use

  • Select based on wastewater color type and COD level
  • In high COD or complex dye cases, combine with PAC and PAM
  • Adjust pH for higher flocculation efficiency
  • Run jar tests to fine-tune dosages before full-scale treatment

FAQ

Q1: What makes this different from ordinary coagulants?

It is engineered to remove dissolved dyes and color, not just suspended solids.

Q2: Does it help reduce COD?

Yes. Strong adsorption of organic colorants results in measurable COD reduction.

Q3: Can it be used with PAC and PAM?

Yes. It’s designed to synergize with common water treatment polymers.

Q4: What is typical dosage?

Depends on wastewater characteristics — typically between 5–50 mg/L.
