Textiles & Manufacturing
ZLD compliance. Colour removal. High-TDS recycling. Nothing leaves your boundary.
Textile effluent is among the most complex industrial wastewater in India — high COD, colour, TDS, and temperature. And CPCB's ZLD mandate means you have no choice but to treat it completely.
Industry Challenges
What makes textiles & manufacturing water treatment complex.
Every industry has unique water treatment requirements. Understanding these sector-specific challenges is the starting point for every NWPL project.
Reactive dye effluent carries intense colour (up to 5,000 Hazen units) that biological treatment alone cannot remove — requiring advanced oxidation or ozonation as a polishing step.
Textile effluent TDS can reach 15,000–30,000 mg/L from dyeing and finishing baths — the highest TDS load of any Indian industrial sector, demanding high-pressure RO and MEE stages.
CPCB ZLD Notification (2016) mandates zero liquid discharge for all textile units in notified clusters. NGT has imposed closure orders on non-compliant units as recently as 2024.
Effluent temperatures up to 60°C from hot dyeing baths can damage biological treatment systems. Heat recovery and temperature management are critical design parameters.
Spinning and weaving facilities generate wash water with high BOD and TSS — a separate stream from dyeing effluent that requires independent treatment or blending management.
