Mechanical Vapor Recompression
Ultra-low energy evaporation through vapour recycling.
Overview
Mechanical Vapour Recompression (MVR) systems use a compressor to recompress evaporated vapour back to the heating side of the evaporator — recycling latent heat and eliminating the need for external steam. This reduces specific energy consumption to 10–20 kWh/m³ of water evaporated, compared to 50–100 kWh/m³ for conventional steam-heated evaporators. Basiia supplies MVR systems integrated with falling film evaporators, brine concentrators, and forced recirculation evaporators for energy-efficient ZLD applications.
Typical Applications
- Energy-efficient brine concentration in ZLD systems
- Produced water evaporation with low operating cost
- Desalination reject concentration
- Industrial wastewater volume reduction
- Power plant ZLD with minimal steam consumption
- Mining process water recovery
- Food and beverage evaporation
- Retrofit of existing steam-heated evaporators
Key Features
Engineered for Performance
Centrifugal or Roots Compressor
High-efficiency centrifugal compressors for large-scale applications; positive displacement Roots blowers for smaller flows — both selected to match vapour volume, compression ratio, and operating temperature.
10–20 kWh/m³ Specific Energy
MVR reduces specific energy consumption by 70–80% versus steam-heated evaporation — delivering significant operating cost savings over the plant lifetime, particularly where electricity is cheaper than steam.
No External Steam Required
Once running, the MVR system is self-sustaining — the compressor provides all the energy needed for evaporation, eliminating dependence on boiler steam and reducing utility infrastructure requirements.
Variable Speed Drive (VSD)
VSD-controlled compressor motor adjusts capacity to match feed flow and concentration — enabling efficient part-load operation and smooth response to process upsets.
Integration with Evaporator Types
Compatible with falling film evaporators, forced recirculation evaporators, and brine concentrators — MVR module supplied as an integrated package or retrofit to existing evaporator vessels.
Vapour Compression Efficiency
High-efficiency impeller and casing design with minimal mechanical losses — compressor isentropic efficiency >80% maintained across the operating range for consistent low energy consumption.
