Sustainable Wastewater Treatment

for the Wet Textile Industry

Transforming Textile Effluents into Resources

The wet textile industry is one of the most water-intensive and pollution-heavy manufacturing sectors in the world. From desizing and scouring to bleaching, dyeing, and finishing, every process generates large volumes of chemically complex wastewater. Our advanced water and wastewater treatment technologies help textile manufacturers reduce water consumption, meet stringent discharge regulations, recover valuable resources, and embrace a truly circular water economy.

At Nenner Haeuser, we provide tailored, end-to-end solutions for textile effluent management from raw water treatment to zero liquid discharge (ZLD).

Raw Water Treatment for Textile Processing

Textile dyeing and finishing require water of consistent quality:

Multimedia Filtration: For turbidity and particle removal
Water Softening or Ion Exchange Systems: To reduce hardness
Ultrafiltration (UF): For suspended solids and bacteria
Reverse Osmosis (RO): For producing high-quality process water
UV or Ozone Disinfection: For microbial control

Primary & Secondary Wastewater Treatment

Wet textile wastewater is rich in:

Colorants (azo dyes, reactive dyes)
COD/BOD from starches, surfactants, fats, and oils
Heavy metals, salts, and pH fluctuations

We design robust systems combining:

Equalization Tanks

For flow and load balancing

pH Neutralization

Using acid/alkali dosing

Coagulation & Flocculation

Using alum/ferric/organic polymers for dye and TSS removal

Primary Clarification

Settling and solid-liquid separation

Biological Treatment
  • • Activated Sludge Process (ASP)
  • • Moving Bed Biofilm Reactor (MBBR)
  • • Membrane Bioreactor (MBR) for high-quality effluent with reduced footprint

Color and Recalcitrant Pollutant Removal (Tertiary Treatment)

Due to persistent dyes and finishing chemicals, tertiary polishing is essential:

Advanced Oxidation Processes (AOPs): TRI3-O

Ozone, UV/H₂O₂, or Fenton for color and non-biodegradable organics

Activated Carbon Filters

For residual COD and color removal

Nanofiltration (NF)

For dye and salt separation

Zero Liquid Discharge (ZLD) and Resource Recovery

To meet discharge standards or enable water reuse:

High-Recovery RO + Brine Concentration

Maximum water recovery with concentrated brine treatment

Evaporator & Crystallizer Systems

Thermal concentration and crystallization technology

Salt Recovery Units

Recover NaCl/Na₂SO₄ for reuse in processes

Sludge Dewatering Systems

Filter press or centrifuge to minimize disposal volume
