Dye Concentration

Dye concentration is an essential process in textile, printing, and pigment industries. At SEDL, we provide a robust and energy-efficient solution for concentrating dye-based effluents and streams. Our systems are specially designed to handle highly corrosive and foamy dye liquids, ensuring high recovery, low operational cost, and environmental compliance.

We are proud to offer a first-of-its-kind fully automated dye concentration system that operates under vacuum, making the process more energy-efficient and safer for heat-sensitive dyes.

Challenges in Dye Concentration

Dye concentration comes with unique challenges

High Foaming

Most dye effluents foam excessively, causing frequent process disruptions.

Corrosion

Dye streams are often chemically aggressive, damaging traditional equipment.

Colour Carryover

Inadequate separation leads to loss of product quality.

High Steam Demand

Conventional evaporators use excessive steam, increasing OPEX.

Fouling & Scaling

Dye residues tend to stick to surfaces, reducing efficiency.

Temperature Sensitivity

Some dyes undergo chemical or colour changes at higher temperatures, leading to degradation or colour distortion. This makes low-temperature evaporation essential to maintain product integrity.

Our Solution

At SEDL, we’ve built a dye concentration system that’s durable, intelligent, and efficient

Vacuum-Based Evaporation

Reduces boiling point and energy consumption, ideal for temperature-sensitive dyes.

Anti-Foaming Design

Special internals to break foam and maintain smooth operation.

Corrosion-Resistant Material

Equipment made of special alloys like SS 316L, duplex steel, or FRP-lined components.

Fully Automated System

Minimal operator involvement, consistent quality.

High Recovery

Up to 85–90% water recovered for reuse or ZLD integration.

Modular & Compact

Easy to install and scalable based on capacity needs.

Why Choose SEDL?

At SEDL, we combine smart engineering with real-world experience to offer dye concentration systems that are cost-effective, energy-efficient, and built to last even for temperature-sensitive dyes.
