ENVR™ Series MVR Evaporator - Mechanical Vapor Recompression Evaporation System

ENVR™ MVR Evaporator - Energy-Efficient ZLD Concentration & Water Recovery

ENVR™ MVR Evaporator concentrates industrial wastewater by evaporating water under controlled conditions and recovering latent heat through mechanical vapor recompression.

The system is designed for continuous operation, delivering high concentration efficiency while minimizing external heat and steam demand.

Key Features

• High-efficiency MVR circulation fan for vapor recompression
  
• Automated temperature and pressure control for stable evaporation
  
• Reduced scaling risk through optimized heat exchange design
  
• Low noise, low vibration, and compact footprint
  
• Integrated PLC control and monitoring system

System Placement

• Installed after primary and secondary wastewater treatment stages

• Integrated into zero liquid discharge (ZLD) systems as the final concentration unit

• Used downstream of membrane processes or clarification stages to minimize effluent volume

 

Typical Applications

• Industrial wastewater concentration and volume reduction

• ZLD projects for plating, metalworking, and surface finishing industries

• Concentration of high COD and high TDS industrial effluents

• Recovery of high-quality distilled water for reuse or safe discharge

• Wastewater streams from cleaning, pickling, acid wash, cuttings, and emulsions

MVR Evaporation System Process Overview

Step 1 – Wastewater Feeding

Industrial wastewater is fed into the evaporator under controlled flow and temperature conditions.

Step 2 – Evaporation & Vapor Generation

Water is evaporated, producing vapor while dissolved solids remain in the concentrate.

Step 3 – Vapor Recompression

Generated vapor is compressed by the MVR fan to increase temperature and pressure.

Step 4 – Heat Reuse & Condensation

Recompressed vapor transfers heat back to the system and condenses into recovered water.

Step 5 – Concentrate Discharge

Concentrated wastewater is discharged for further treatment or crystallization.

Technical Specifications

The following performance data is based on standard testing conditions. Actual performance may vary depending on feed water quality and operating parameters.

Note: 

• Feed water: tap water; hardness ≤ 10 °dH; inlet temperature ≥ 15 °F.
• Values shown refer to a unit at normal operating temperature.
• All data is based on tests using tap water. Actual performance may vary depending on site conditions.
• Performance data for specific process waters will be confirmed through customer-specific engineering calculations.
