Read the Case StudyWater Management for Textile Operations
Textile manufacturing generates wastewater containing dyes, chemicals, suspended fibres, and high organic loads from sizing, scouring, bleaching, dyeing, and finishing operations. Our treatment solutions address the unique challenges of colour removal, chemical oxygen demand reduction, and water reuse for sustainable textile production. Colour removal by coagulation, oxidation or membrane treatment is combined with COD reduction and polishing to handle the full dyehouse load. We engineer each plant for water reuse, cutting both freshwater cost and the coloured-discharge risk that regulators scrutinise.
Advanced treatment processes for removing dyes and pigments from textile wastewater to meet strict colour discharge standards.

Explore Textile GarmentUnderstanding the contaminants that drive treatment design
Reactive, azo, and sulphur dyes create highly coloured effluent that is visible and heavily regulated.
Batch dyeing creates peaks in flow, pH, temperature, and organic load that shock conventional systems.
Sizing agents, surfactants, and scouring liquors push organics to very high concentrations.
Heavy metals, formaldehyde, chlorinated organics, and aromatic amines require targeted removal.
Loose fibres clog pumps, valves, and biological units if not removed upstream.
Salt and caustic soda from mercerizing inhibit advanced biological treatment and drive conductivity.

EU IED BAT-AELs for textile finishing: COD 30–160 mg/L; TSS 5–30 mg/L; AOX 0.05–0.5 mg/L; total-N 5–15 mg/L. ZDHC MRSL restricts ~250 hazardous substances (APEOs, chlorobenzenes, formaldehyde, PFAS, certain azo dyes). Colour removal almost always requires coagulation (FeCl3) plus AOP (ozone or Fenton) or activated carbon polishing.
