Wastewater streams can be concentrated in a Galicos module at low cost using waste heat from e.g. ventilation air or outside air.
In this process, the airflow is almost saturated with vapor of the liquid due to the large contact area between thousands of elongated bubbles and the film-shaped liquid flow (see working principle).
The evaporation capacity depends on the temperature and relative humidity of the applied airflow.
The airflow saturated with moisture can usually be discharged directly into the atmosphere. If the disposed airflow contains hazardous substances (such as vapors of hydrocarbons) additional measures are needed.
- Low costs
- Not sensitive to fouling
- Easily to clean
- Low own energy consumption
- Simple operation and maintenance
- Modular expandable
- Where appropriately combined applicable as a liquid thickener and air scrubber
