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. Processes like desizing, scouring, bleaching, dyeing, printing, and finishing generate large volumes of complex wastewater containing suspended solids, dyes, salts, surfactants, and toxic chemicals.

At Nenner Haeuser, we provide tailored, end-to-end solutions for textile effluent management—from raw water treatment to Zero Liquid Discharge (ZLD). Our systems ensure compliance with stringent environmental regulations while enabling maximum water recovery and reuse.

Raw Water Treatment for Process Quality

High-quality water is essential for dyeing and finishing to ensure product consistency.

Pre-Treatment
  • Multimedia Filtration (Removal of suspended solids)
  • Activated Carbon Filtration (Removal of organics & chlorine)
  • Softening (Hardness reduction for dyeing efficiency)
Advanced Purification
  • Ultrafiltration (UF) (Removal of colloids & pathogens)
  • Reverse Osmosis (RO) (Reduction of TDS for specific process needs)

Primary & Secondary Wastewater Treatment

Treating complex effluents rich in Colorants, COD/BOD, Heavy Metals, and Salts.

Physio-Chemical Treatment
  • Equalization & Neutralization
  • Coagulation & Flocculation (Color/TSS removal)
  • Tube Settlers / Clarifiers
Biological Treatment
  • Activated Sludge Process (ASP)
  • MBBR (Moving Bed Biofilm Reactor)
  • MBR (Membrane Bioreactor)
Sludge Handling
  • Filter Presses
  • Decanters / Centrifuges
  • Sludge Drying Beds

Tertiary Treatment Breakdown

Removing recalcitrant organics and trace colors for compliance or reuse.

Advanced Oxidation Processes (AOP)

Utilizing Ozone, UV, or Fenton’s reagent to degrade hard-to-treat organic compounds and eliminate residual color.

Filtration & Adsorption

Activated Carbon filters for polishing and Ultrafiltration (UF) as pretreatment for RO, ensuring silt density index (SDI) control.

Zero Liquid Discharge (ZLD)

Maximum water recovery and salt management for a circular economy.

High-Recovery RO

Multi-stage Reverse Osmosis systems to recover up to 90-95% of water for reuse.

Evaporation (MEE / MVR)

Treatment of RO reject (brine) to separate water from mixed salts.

Crystallization & Salt Recovery

Zero liquid discharge with potential for salt recovery (Glauber's salt).
