Core Services

Comprehensive expertise delivered by experienced engineers using industry-leading tools and methodologies.

Industry Expert

Textile and denim wastewater specialists experienced in the colour, sizing, starch and high-pH effluent of dyeing, washing and finishing.

Process Knowledge

Process design across coagulation, DAF, biological treatment, advanced oxidation and membrane reuse — matched to denim laundry and finishing streams.

Compliance

Discharge engineered to local sewer and environmental limits, with the sampling, monitoring and documentation regulators require.

Sustainable

Water reuse, colour removal and chemical recovery that cut fresh-water demand and discharge volume in textile production.

>95%

Colour and suspended-solids removal achievable with coagulation, DAF and final polishing on denim effluent.

Denim Finishing Wastewater Treatment

Treatment Challenge

Denim production creates distinctive wastewater challenges including high concentrations of indigo dye, pumice stone dust, elevated pH from caustic washing, and organic compounds from enzyme and bleach treatments. The dark colour and high solids content require targeted treatment approaches.

High BOD and COD loads requiring biological treatment
Colour removal to meet discharge consent limits
Variable flow and batch processing operations
Water reuse potential for sustainability targets

Our Solution

Our denim-specific treatment systems feature grit removal for pumice, chemical precipitation for indigo colour, and biological treatment for BOD and enzyme residues. Advanced oxidation options achieve the stringent colour removal required for discharge or water reuse applications.

Integrated treatment train design
Process-specific chemical optimisation
Automated control with SCADA integration
Compliance with BAT and ZDHC standards

Treatment Process Overview

1

Pre-Treatment

Screening, grit removal, and equalization to protect downstream equipment and balance flows.

2

Chemical Treatment

Coagulation, flocculation, and pH adjustment for solids and colour removal.

3

Biological Treatment

Activated sludge, MBBR, or SBR for BOD and nutrient removal.

4

Polishing & Reuse

Filtration, activated carbon, and optional RO for water recovery.
