Textile & Dyeing
Textile Printing & Dyeing Wastewater Reuse
Colour removal, biological treatment and membrane reuse for a printing and dyeing mill.
Challenge
Project Requirements
Dyeing effluent carried high colour, COD and salinity, and the mill faced both discharge limits and rising water costs.
Engineered Solution
- Coagulation and air flotation for colour and suspended solids
- Anaerobic plus aerobic biological treatment for COD and ammonia
- Ultrafiltration and reverse osmosis for reclaimed water production
- Concentrate handling and sludge dewatering
Results
Outcome On Site
Discharge quality within local standards
A large share of process water supplied from reuse
Water purchase and discharge fees both reduced
