Why Textile Wastewater Is Difficult
Textile wastewater changes with dye type, production batch, auxiliaries, pH and washing process.
High Visible Color
Reactive, disperse and mixed dyes can leave strong color after biological treatment.
Variable Wastewater
Batch production makes wastewater quality change frequently.
Floc and Settling Problems
Color removal alone may not be enough; coagulation and settling must also be checked.
Chemical Treatment Direction
For many textile wastewater samples, a combined test gives better evaluation than testing one product only.
| Chemical | Role | When to Use |
|---|---|---|
| Water Decoloring Agent | Color removal and cationic coagulation support | When visible color is the main issue |
| PAC | Coagulation and turbidity reduction | When floc is weak or water remains turbid |
| PAM | Floc growth and settling support | When settling is slow or flocs are small |
