Textile Industry Wastewater Treatment

Color removal, chemical treatment and water reuse. We solve the textile industry's most complex wastewater challenges.

Wastewater Challenges of the Textile Industry

Color
Azo, reactive and disperse dyes — very strict color discharge limits
Temperature
50-80°C dye-house effluents — cooling required before biological treatment
Chemicals
Salt, alkali, peroxide, dyestuffs — a complex composition
Water Use
1 kg of fabric = 100-200 L of water — reuse is a must

Challenges

  • Dye baths — high color, high salt (NaCl 60-100 g/L), pH 10-12
  • Washing / desizing effluents — starch, PVA, surfactants
  • Mercerizing wastewater — caustic soda recovery required

FAQ

Textile — Frequently Asked Questions

We have compiled the questions our customers ask most often. If you can't find the answer you are looking for, get in touch with us.

What are the main treatment challenges of textile wastewater?

Textile wastewater is characterized by high color (dyes), high pH (alkaline dyeing), high salt content (especially reactive dyeing), refractory organics (especially azo dyes) and highly variable flow and load. COD of 800-3,000 mg/L and color of 500-2,500 Pt-Co are typical.

Which treatment technologies are used for textiles?

The standard configuration is: equalization + neutralization + coagulation-flocculation (PAC + polymer) + biological treatment (activated sludge/MBR) + (where required) advanced oxidation (ozone/Fenton) or activated carbon. Advanced oxidation or nanofiltration may be required for color removal. RO + evaporator is used for salt recovery.

What is the investment cost of a textile WWTP?

Investment and operating costs vary with the facility, flow rate and discharge target — request a quote for a free preliminary assessment.

Can you retrofit an existing textile mill?

Yes. GESU has delivered numerous retrofit projects in the textile industry. To resolve discharge limit exceedances (color, COD), we typically recommend coagulation optimization, MBR conversion or a tertiary activated carbon column.
