MVR Crystallizer System

Overview of MVR Crystallizer Technology

The MVR Crystallizer (Mechanical Vapor Recompression Crystallizer) is an advanced system designed for concentration and crystallization of industrial liquids such as high-salinity wastewater, chemical brine, and process effluents.
By recovering and reusing vapor heat through mechanical vapor recompression, the system dramatically reduces energy consumption compared to conventional multi-effect evaporators.

This technology is widely applied in Zero Liquid Discharge (ZLD) systems, allowing industries to recover clean water and valuable solids while minimizing environmental impact.

Working Principle of MVR Crystallization

1. Feed Heating and Circulation:
   Wastewater or process liquid is circulated through a heat exchanger using a forced circulation pump, ensuring stable flow even with high-viscosity or scaling solutions.

2. Evaporation Stage:
   Under vacuum conditions, water or solvent vaporizes at a lower temperature. The vapor is then compressed by an MVR compressor, increasing its pressure and temperature.

3. Heat Recovery and Reuse:
   The compressed vapor transfers its latent heat back to the heat exchanger, sustaining the evaporation cycle with up to 90% energy recovery.

4. Crystallization and Solid Separation:
   As concentration increases, salts or solids begin to crystallize. The slurry is then discharged for solid-liquid separation via centrifuge or filter press, achieving Zero Liquid Discharge.

Key Advantages of the MVR Crystallizer System

• High Energy Efficiency: Up to 90% energy savings versus traditional evaporators.

• Stable Operation: Forced circulation minimizes fouling and scaling.

• Compact Design: Smaller footprint and modular configuration for easy installation.

• Corrosion Resistance: Available in Titanium, Duplex, or Stainless Steel for harsh chemical environments.

• ZLD Compliance: Enables total recovery of clean water and solid salts for reuse.

Applications of MVR Crystallization Technology

• Industrial Wastewater Treatment: Concentration and crystallization of brine, RO reject, and chemical effluents.

• Chemical and Fertilizer Manufacturing: Recovery of salts and chemical by-products.

• Food and Pharmaceutical Industries: Crystallization of organic and inorganic compounds with temperature-sensitive properties.

• Mining and Metallurgy: Brine management and valuable mineral recovery.
