Garment Washing Wastewater Color Removal Chemical
Garment washing wastewater may contain dyes, auxiliaries and suspended solids, so chemical selection should be tested before bulk supply.
Typical Problems
- Cloudy or colored wastewater after washing process.
- Color changes according to fabric and dye type.
- Need clear supernatant and acceptable sludge settling.
Chemical Test Direction
- Water decoloring agent for color removal.
- PAC for coagulation and turbidity reduction.
- PAM for floc settling and sludge separation.
Sample Request Tips
- Send raw and treated wastewater photos if available.
- Provide daily flow and current ETP process.
- Tell us target discharge or reuse requirement.
Quick Selection Reference
Use this as a starting point only. Final dosage and sequence should be confirmed by jar test with actual wastewater.
| Situation | Typical Concern | Suggested Test Direction |
|---|---|---|
| Sri Lanka | Garment washing/apparel wastewater | Sample + jar test recommended |
| Bangladesh | Dyeing and washing ETP | Check color and COD |
| Vietnam | Printing and washing wastewater | Optimize PAC/PAM sequence |
