Ambient air is the only driving force in the EM System (Mechanical Evaporation). The capacity and operating cost depend on weather conditions. The higher the temperature and the lower the relative humidity, the higher the evaporation capacity.

The system is modular and the number of evaporators are designed according to the wastewater flow-rate and the local climate.

How does the EM System work?

It is an evaporative process based on the capacity of the ambient air to absorb water from an effluent. The evaporation capacity depends on the weather conditions (temperature and relative humidity).

It is particularly suitable for making use of residual thermal energy. We have numerous references in the treatment of leachates and wastewater from the Chemical and Agri-food industries.

Our evaporate is a humid air that complies with the most stringent international standards for airborne emissions and air quality.

The temperature, pressure and pH controls of the process, together with the mist elimination system, guarantee an environmentally-friendly evaporate.


The special labyrinth-type design of the droplet separator (demister) guarantees the elimination of virtually all drops from the air outlet.

The double-chamber evaporator morphology, together with the hydraulic distribution of wastewater, complement the efficient separation of droplets.


The concentrate contains the pollutants from wastewater.

We guarantee the minimum concentrate generation, maintaining the maximum treatment capacity with the minimum energy consumption.

We achieve this through the optimal design and combination of the system components.

If the concentrate is not going to be reused in the client’s processes, we can stabilize it for easy disposal.


The wastewater circulation pump and the ambient air fan are the only driving equipment in our wastewater treatment plants.

Energy consumption: 10 – 80 kWh/m3 (1,5 – 12% of latent heat evaporation)


The packing is the physical support where the ambient air and the wastewater come into contact.

It consists of a 3D structured grid with a large specific surface area.

Its design guarantees the best wastewater evaporation performance on the market, with the minimum air resistance.
