Colour Reducing Agents for US Sugar Mills and Textile ETPs — Dicyandiamide-Formaldehyde Chemistry for ICUMSA and ADMI Colour Control

Innovacorp India Pvt Ltd is a manufacturer, exporter and supplier of Colour Reducing Agents for US sugar mills and textile effluent treatment. Our Dicyandiamide-Formaldehyde (DF) based formulations are designed to target colour bodies at two different measurement scales — ICUMSA units in sugar processing, and ADMI units in textile wastewater.

Why "Colour" Means Two Different Things in Sugar and Textile

Anyone who has worked across both industries knows the confusion: a sugar mill talks about ICUMSA units, a textile ETP talks about ADMI units. They are not the same measurement, and the chemistry that works for one does not automatically work for the other. ICUMSA measures absorbance at 420 nm after dissolving the sugar sample in a pH 7.0 buffer — it is a direct measure of the colour in the sugar crystal . ADMI measures colour in wastewater using a different spectral method, and US textile mills face discharge limits expressed in ADMI units .

Our DF-based colour reducing agents work on the chemistry that drives both: the anionic colour bodies that carry the visible pigment. In sugar, those are phenolic compounds, melanoidins and caramels. In textile effluent, they are reactive dye molecules. The same charge-neutralisation and precipitation mechanism applies, but the dosing and the testing method differ.

How DF Resin Works on Reactive Dyes in Textile Effluent

Dicyandiamide-formaldehyde condensation products have been studied specifically for reactive dye removal. Research on a modified DF resin (DF1, cross-linked with hexamethylenetetramine) showed a maximum colour removal of 98.8% from Reactive Brilliant Red X-3B at a dosage of 35 mg/L . The same study used infrared spectroscopy to confirm that a chemical reaction occurs between the DF resin and the dye molecule — it is not just physical adsorption, but a chemical interaction that stabilises the floc .

In practical terms, this means the DF chemistry can handle the complex dye structures that conventional coagulants struggle with. US textile mills facing ADMI discharge limits can use this as a polishing step after primary treatment.

How the Same Chemistry Works in Sugar Processing

In sugar, the colour bodies are different — but the charge interaction is similar. Phenolic compounds, melanoidins and caramels carry negative charges that DF-based polymers can neutralise and precipitate. The difference is the dosing point: sugar mills dose at juice clarification or syrup treatment, where the colour load is highest and the temperature is still manageable.

The target is to lower ICUMSA colour before crystallization. Raw sugar typically has high ICUMSA values (up to 16,000 IU), while refined sugar targets values below 40 IU . The colour reducing agent helps bridge that gap by removing colour bodies before they concentrate in the crystal.

Where Our Colour Reducing Agents Fit in US Facilities

  • Sugar mills (juice clarification): Dosed before or during clarification to target phenolic colour bodies.
  • Sugar refineries (syrup treatment): Dosed in the syrup circuit before crystallization, to lower ICUMSA in the final crystal.
  • Textile ETPs: Dosed as a polishing step after primary coagulation, to meet ADMI discharge limits.
  • Dye house effluent: For reactive dye removal where conventional coagulants underperform.

Grades We Manufacture, Export & Supply

  • Sugar-grade DF formulation: For juice clarification and syrup treatment, optimised for ICUMSA reduction.
  • Textile-grade DF formulation: For reactive dye removal, optimised for ADMI reduction.
  • High-charge variant: For high-colour loads where standard dosage is insufficient.

Dosage & Feeding Points

Sugar (juice/syrup): Typical dosage ranges from 100 to 500 ppm on juice or syrup, depending on colour load. Feed at the clarifier inlet or syrup treatment tank. Final dosage is confirmed after a jar test on your juice.

Textile ETP: Research shows 35 mg/L DF resin achieved 98.8% colour removal from Reactive Brilliant Red X-3B . For mixed dye effluent, dosage is typically set by jar test and adjusted to meet ADMI discharge limits.

Frequently Asked Questions

How are colour reducing agents used in US sugar mills?

In US sugar mills, colour reducing agents are dosed at the juice clarification or syrup treatment stage to target phenolic compounds, melanoidins and caramels. The goal is to lower ICUMSA colour in the clarified juice before crystallization, supporting higher-grade sugar production.

What is the ICUMSA method for measuring sugar colour?

ICUMSA colour is measured by dissolving the sugar sample in a pH 7.0 buffer, then measuring absorbance at 420 nm. The result is expressed in ICUMSA units (IU). Raw sugar typically has high IU values, while refined sugar has low IU values.

Can the same colour reducing agent be used for textile effluent in US?

Dicyandiamide-formaldehyde (DF) based formulations are used for textile dye effluent decolourization. Research shows DF resin can achieve up to 98.8% colour removal from Reactive Brilliant Red X-3B at 35 mg/L dosage.

Do you supply colour reducing agents in bulk to US industries?

Yes. We manufacture, export and supply colour reducing agents in 35 kg carboys, 200 L drums and 1000 L IBCs suitable for US sugar mills and textile ETPs. Technical support is available across US.
