High COD Levels
1,500–5,000 mg/L exceeding limits (Tairan Chemical, n.d.). COD nearly double domestic wastewater (ScienceDirect, 2025).

Advanced textile wastewater treatment
Market Signal
The textile industry produces some of the most complex and chemically difficult-to-degrade wastewater across industrial sectors.
The global textile wastewater treatment market is rapidly expanding due to increasing regulatory pressure and operational complexity.
Challenges
1,500–5,000 mg/L exceeding limits (Tairan Chemical, n.d.). COD nearly double domestic wastewater (ScienceDirect, 2025).
Dyes, surfactants, bleaching chemicals, finishing agents, and heavy metals.
Resistant to biological treatment processes.
High compliance pressure across facilities.
Penalties up to $68,445 (eCFR, 2025). Sludge = 40–60% of costs (TPO Magazine, 2026).
Fast fashion increases wastewater variability.
