Textile & Dyeing Wastewater Treatment
Dyes, starch, and fibers from dyeing & finishing — engineered systems that cut COD and color to discharge limits
Dyes and Starch Make Textile Effluent Hard to Treat
Dyeing, printing, and finishing plants discharge water loaded with reactive dyes, sizing starch, fibers, and salt. The color is not just cosmetic — it signals recalcitrant organics that ordinary biological treatment cannot fully remove.
A Complete Treatment Line, Engineered to Order
From pre-screening to advanced color removal, every stage is sized to your flow and discharge target.
1 · Pretreatment
Bar screens and an equalization tank remove fibers and smooth out pH and salt swings.
2 · DAF Clarification
Coagulation + dissolved air flotation strips out color, fibers, and suspended solids before biological treatment.
3 · Biological + Polish
A/O plus advanced oxidation or MBR polishing removes residual COD and color.
4 · Sludge Dewatering
Belt or screw press dewaters the dyed sludge to 20–35% cake solids for disposal.
The Two Machines That Do the Heavy Lifting
Dissolved Air Flotation (DAF) System
With coagulation dosing, DAF is the first major color-removal step for textile effluent — lifting dyes, fibers, and solids to the surface before they reach your biological stage.
MBR Membrane Bioreactor
For mills that need to reuse water or meet tight color limits, an MBR combines biological treatment with membrane separation — producing effluent clean enough for recycling back into washing and rinsing.
Typical System Configurations
Reference line-ups by scale — the final design depends on your flow and discharge target.
Small · Garment Washing
≤ 100 m³/d
Bar screen + coagulation DAF-30 + sludge dewatering.
Medium · Dyeing / Printing
100–500 m³/d
Bar screen + equalization + DAF-100 + A/O + sludge dewatering.
Large · Integrated Mill
> 500 m³/d
Bar screen + equalization + DAF-200 + A/O + MBR polish + sludge dewatering.
