Understanding the Difference
Choosing between MVRS (Multi Vapor Recovery System) and traditional evaporators is crucial for your ZLD plant's efficiency and operating costs.
Quick Comparison
| Feature | MVRS | Traditional |
|---|---|---|
| Steam Consumption | 80-85% Less | Standard |
| Operating Cost | 60% Lower | High |
| Footprint | Compact | Large |
| Recovery Rate | 95-98% | 85-90% |
| Maintenance | Low | High |
How MVRS Works
MVRS uses multiple-effect evaporation with vapor compression, reusing steam efficiently:
- First effect generates vapor from feed
- Vapor feeds second effect (no fresh steam)
- Vapor compression increases efficiency
- Condensate collected as pure water
Benefits of MVRS
- Lower Operating Cost - Up to 60% savings on steam
- Higher Recovery - More water recovered per unit of energy
- Compact Design - Smaller footprint
- Environmentally Friendly - Lower carbon footprint
When to Choose Traditional
Traditional evaporators may still be suitable for:
- Very small capacity requirements (< 10 KLD)
- Intermittent operation
- Very high temperature applications
Conclusion
For most industrial ZLD applications, MVRS offers superior efficiency and lower operating costs. The higher initial investment pays back within 2-3 years through operational savings.
