Multi-Effect Evaporation (MEE) System
Multi-Effect Evaporation (MEE) System, Efficient Thermal Evaporation for Industrial Applications
The Multi-Effect Evaporation (MEE) system is a highly efficient thermal process designed to concentrate liquid streams by utilizing the latent heat of vaporization across multiple stages. By reusing vapor energy from one effect to the next, MEE systems significantly reduce steam consumption, making them ideal for industries focused on sustainable and cost-effective operations.
Key Features & Advantages
- Energy Efficiency: Multiple-effect design recycles steam across stages, greatly reducing overall energy use.
- Flexible Configuration: Tailored designs ranging from double to quintuple effects, with options for forward, backward, or mixed feed.
- High Heat Transfer Rates: Short residence times and rapid heat exchange minimize thermal degradation.
- Low Fouling Design: Optimized to reduce scaling and extend cleaning intervals.
- Fully Automated Operation: Integrated PLC/SCADA systems enable stable and precise control.
Applications
- Zero Liquid Discharge (ZLD) Systems: Concentrates high TDS brines and minimizes final waste volume.
- Chemical Processing: Recovers and concentrates valuable chemicals while maintaining product quality.
- Food & Beverage Industry: Used for concentrating juice, dairy, syrup, and other heat-sensitive liquids.
- Pharmaceuticals: Supports solvent recovery and intermediate concentration with low thermal stress.
- Textile & Dyeing Plants: Efficiently removes dyes and chemicals from wastewater streams.
System Components
- Evaporator Heat Exchangers: Provide efficient thermal transfer across each effect.
- Vapor-Liquid Separators: Separate generated vapor from concentrated liquid at each stage.
- Circulation Pumps: Maintain flow consistency and optimal heat distribution.
- Vacuum System: Enables evaporation at lower temperatures for heat-sensitive fluids.
- Condenser Unit: Condenses final vapor into reusable or dischargeable water.
- Automated Control Panel: Centralized PLC system for real-time monitoring and operation.
Evaporator Types Available
- Falling Film Evaporator: Best for low-viscosity fluids and minimal scaling applications.
- Forced Circulation Evaporator: Ideal for high TDS, high COD wastewater and viscous materials.
