MODELS AND MAIN TECHNICAL FEATURES

We design and manufacture falling-film vacuum evaporators, which offer high performance in the treatment of low-viscosity, heat-sensitive industrial wastewater with a low risk of scaling.

Our falling-film evaporators use mechanical vapor recompression (MVR) technology, which recovers and reuses the latent heat generated during evaporation.

This combination minimizes energy consumption and enables the high-performance treatment of heat-sensitive effluents.

Our falling-film model is the ENVIDEST MVR FF, and it can treat flow rates of up to 1.980 liters/hour..

In addition to falling-film evaporators, we offer a wide range of wastewater evaporators for the management of industrial effluents.

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 receives heat from the tube walls, causing part of the water to evaporate.

The reduced film 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 its downward flow, 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 vapor produced is condensed in a condenser, obtaining a high-quality distillate.

Optionally, the vapor can also be reused as a heat source in other systems.
