AVAILABLE MODELS AND MAIN TECHNICAL FEATURES

We design, manufacture, and install falling-film vacuum evaporators, a highly efficient technology for industrial wastewater treatment.

These systems separate high-quality distilled water from effluents with high concentrations of contaminants, facilitating their reuse or more efficient waste management.

They operate under vacuum to reduce the boiling temperature and use mechanical vapor recompression (MVR) technology, which recovers and reuses the latent heat generated during evaporation. This combination minimizes energy consumption and enables heat-sensitive effluents to be treated with high performance.

Our range focuses on the ENVIDEST MVR FF series, designed to treat flow rates of up to 1.980 l/h.

KEY ADVANTAGES

All our falling-film evaporators are particularly suitable for:

  • High heat transfer efficiency, facilitating rapid evaporation and high energy efficiency.
  • Minimal thermal degradation of the product. Ideal for processing heat-sensitive products while preserving their properties.
  • Reduced fouling formation, which decreases cleaning and maintenance requirements.
  • High processing capacity and continuous operation

OPERATION OF OUR FALLING FILM EVAPORATORS

1

Power distribution

The effluent enters through the upper part of the evaporator and is evenly distributed among the heat exchanger tubes.

Thanks to gravity, the liquid descends, forming a thin film on the inner walls of the tubes.

2

Falling-film evaporation

As it flows downward, the liquid film receives heat from the tube walls, causing part of the water to evaporate.

The film’s reduced thickness maximizes heat transfer and minimizes residence time, reducing the risk of thermal degradation and fouling.

3

Vapor and concentrate separation

At the end of the tubes, the mixture enters a separator where the generated vapor is separated from the concentrate.

The concentrate is discharged or recirculated, depending on the final concentration required by the process.

4

Condensation and distillate recovery

The produced vapor is condensed in a condenser or reused as a heat source in other systems, resulting in a high-quality distillate.

The concentrate leaves the system at the desired concentration.
