Glass processing wastewater is characterized by high alkalinity and abrasive suspended solids, which pose risks to membranes and pipelines.
Wastewater Features
- pH often above 10
- Fine glass grinding particles
- Poor biodegradability
Role of PAFC / PAC
PAC or PAFC neutralizes alkalinity and removes fine particles through coagulation, achieving:
- Over 90% SS removal
- Effluent turbidity ≤ 5 NTU
This ensures safe operation of ultrafiltration systems.
Practical Benefits
- Reduced membrane fouling
- Lower cleaning frequency
- Stable system operation
Conclusion
PAC is a key chemical in glass wastewater pretreatment, protecting advanced filtration units and ensuring consistent effluent quality.
