MVR Evaporation System for Industrial
MVR Evaporation System for Industrial
King Dupont’s Mechanical Vapor Recompression (MVR) Evaporation System is an energy-efficient solution for industrial liquid concentration and wastewater treatment, replacing traditional evaporation with closed-loop secondary vapor compression and recycling. It cuts steam consumption by 90%+, slashes operating costs by 40-70%, and features a compact design—30-50% smaller footprint than conventional systems—while enabling Zero Liquid Discharge (ZLD) for high-salinity wastewater.
Core Technical Parameters
- Steam consumption: 0.03–0.05 t steam / t water evaporated
- Electricity consumption: 20–35 kWh / t evaporation
- Energy savings: Up to 90% vs traditional evaporation
- Temperature control accuracy: ±1°C (for low-temperature applications)
Typical MVR Evaporation Process
The typical process flow of an industrial MVR evaporation system includes:
- Feed liquid is preheated via heat exchangers
- Heated liquid enters the evaporator for water evaporation
- Secondary vapor is purified in a vapor separator
- Vapor compressor raises vapor temperature by 8–15°C
- Compressed vapor cycles back to the evaporator as a heating source
- Concentrated liquid is discharged; condensate is recovered for reuse
This closed-loop energy reuse process allows MVR systems to operate with minimal external steam supply.

Industrial Applications of MVR Evaporation Systems
MVR evaporation systems are widely used in various industries:
MVR-wastewater-treatment
1.High-Salinity Wastewater Treatment
Suitable for: Metal surface treatment wastewater, electroplating wastewater, membrane concentrate, rare earth mining wastewater
Adaptable conditions: 0.1–0.4 MPa low-pressure steam; 100–500°C exhaust gas waste heat recovery; 50–100°C flash steam recovery
- Fully sealed process: Leak-free, safe treatment for heavy metal/radioactive hazardous wastewater
- Resource recovery rate ≥96% (reusable distilled water + salt/metal crystals)
- 60%+ energy savings; 24-hour continuous operation
- Lower treatment costs than traditional evaporation
1.Nuclear Industry High-Salinity Wastewater Treatment
An MVR evaporation system was installed for treating low-radioactivity wastewater containing heavy metals.
The system operates continuously with no leakage and converts wastewater into reusable distilled water and concentrated heavy-metal solution.
Treatment cost: 23 RMB per ton of wastewater.
2.Rare Earth Mining Wastewater Resource Recovery
For wastewater containing high concentrations of calcium chloride and ammonium chloride, the MVR system converts wastewater into reusable distilled water while producing valuable salt by-products.
Treatment cost: 120 RMB per ton of wastewater, while generating additional economic value from recovered salts.
2.Bio-Fermentation Waste Liquid Treatment
Suitable for: Active microbial fermentation liquids, bio-enzymes, functional sugars, antimicrobial peptides
Core design: Ultra-low temperature evaporation (40–50°C) to preserve biological activity and product quality
Typical capacity: 200–2000 kg/h evaporation
- 40–50°C low-temperature evaporation for heat-sensitive substrates
- 3–10× higher evaporation efficiency than traditional systems
- Steam consumption reduced to 10% of conventional processes; 60%+ energy savings
- Fully automated control with precise temperature accuracy
1.Functional Sugar Production Project
A two-stage MVR evaporator system was installed for functional sugar concentration.
Operating temperature: 45°C
Energy consumption reduced by 70% compared with traditional evaporation systems.
Bio-Fermentation Extract Concentration
A low-temperature MVR evaporator was used to concentrate fermentation extracts at 40–50°C, preserving biological activity while improving concentration efficiency by 3×.
2.Antimicrobial Peptide Production
A customized MVR evaporator maintains 40–50°C evaporation temperature, ensuring product stability.
Energy consumption is only 25% of traditional evaporation systems.
