Dyes, pigments and colorants are widely used in various industries — textiles, pharmaceuticals, food, cosmetics, plastics, paints, inks and paper — and they produce huge amounts of undesirable coloured industrial wastewater. Wastewater containing dyes and pigments not only makes them aesthetically unacceptable but also creates serious health risk factors for living organisms and the environment.
Ion Exchange offers a wide range of membrane solutions for dye desalting, concentration and purification of the finished products for the dye industry.
How It Works
Conventional desalting processes leave the final dye with a high salt content, which reduces spray-drying efficiency and affects product yield and manufacturing cost. INDION advanced membrane filtration overcomes these limitations of conventional desalting.
Integrating dye desalting, concentration and purification with a downstream Zero Liquid Discharge (ZLD) system helps in effluent treatment and, more importantly, recovers 95% to 98% of the dye.
Benefits of Membrane Systems
Improved Quality and Stability
Of the finished dye product.
Improved Yield and Savings
In disposal cost, with increased dryer throughput and capacity.
Lower Water and Compliance Cost
Reduced transport and storage costs of dyes, savings on fresh water cost, and compliance with pollution control board regulations.
