How UF Technology Improves Water Quality
Ultrafiltration (UF) Water Treatment Systems: 2025 Complete Guide
How UF Technology Works
1. Molecular Filtration: 0.005-0.01μm pores remove:
• 99.99% bacteria (E.coli, Legionella)
• 99.9% viruses (20-300nm)
• 100% suspended solids
2. Mineral Retention: Preserves Ca²⁺/Mg²⁺ beneficial minerals
3. No Chemicals: Physical barrier filtration
Industry Data: UF systems achieve 95% recovery rate vs 75% for conventional filtration (AWWA 2023)
UF vs Traditional Filtration
| Parameter | UF System | Sand Filter |
|---|---|---|
| Filtration | 0.01μm | 50-100μm |
| Bacteria Removal | 99.99% | 60-80% |
| Water Recovery | 90-95% | 70-85% |
| Footprint | 1m²/10m³ | 3m²/10m³ |
| Automation | Full | Manual |
5-Stage UF Process
1. Pretreatment
• Coagulation: Poly-Aluminum Chloride dosing
• Sand Filtration: Removes >50μm particles
• Carbon Adsorption: Eliminates chlorine
2. Ultrafiltration
• Hollow Fiber Membranes:
Material: PVDF/PES
Flux: 50-100 LMH
• Operating Pressure: 1-5 bar
3. Backwash Cycle
✔ Every 30-60 minutes
✔ 30-60 second duration
✔ 95% water recovery
