Textile Wastewater Treatment Chemicals – Dye Removal Coagulation Solutions

Textile Industry Wastewater Treatment Solutions

The textile industry produces some of the most challenging industrial wastewater. Hydrochemix provides proven chemical solutions for textile effluent treatment plants worldwide.

Textile Wastewater Challenges

  • Reactive dyes, disperse dyes, vat dyes in effluent
  • COD ranging from 800 to 8,000 mg/L
  • High suspended solids from fiber and fabric residues
  • pH variation from 4 to 12 depending on process stage
  • High temperature (40-70C) in many discharge streams

Hydrochemix Treatment Program

Primary Treatment: PAC Coagulation

Our spray-dried PAC 30% achieves superior color removal (90-99% for most reactive dyes) through charge neutralization and sweep coagulation. Typical dosage: 200-800 mg/L depending on dye concentration.

Secondary Treatment: PAM Flocculation

Cationic PAM with medium-high charge density enhances floc formation and settling velocity. Combined with PAC, it achieves COD reduction of 60-85%.

Tertiary Polishing

For zero liquid discharge (ZLD) compliance or water reuse applications, our chemicals are compatible with MBR, activated carbon, and advanced oxidation processes.

Case Study: Vietnamese Denim Manufacturer

  • Flow: 3,000 m3/day, Influent COD: 2,000-4,000 mg/L
  • PAC dosage: 400 mg/L, Cationic PAM: 2 mg/L
  • Results: 82% COD reduction, 95% color removal, sludge volume reduced by 35%
