Working Principle:

The liquid flows down along an inclined plat and so generates by cavitations a slightly negative pressure in the downward directed, protruding openings that are present on the upper surface of this plate. The negative pressure causes the gas to pass from underneath the plate into the flow of liquid as long stretched bubbles that stay long enough in contact with the liquid to become saturated with vapour exchange other components or thermal energy. A low pressure ventilator will transport the gas and enhance the gas/liquid contact.

This patented method provides a very intensive gas/liquid contact, offering an optimal exchange of components at minimal energy input. Even waste energy e.g. from heating, cooling and ventilating may be put to good use.


  • Low energy consumption
  • Not sensitive to fouling
  • Compact, modular and robust construction
  • Simple operation and no maintenance

The best solution for:

  • Thickening of liquids
    GaLiCos behuizing
    WORKING PRINCIPLE 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
  • Scrubbing of (hot) gasses
    Working principle Contaminated ventilation air or flue gases can be washed by leading the gas stream through one or more Galcios Units (see working principle). Dust and soot particles are trapped in the liquid while caloric energy (when present in
  • Stripping and Cooling of liquids
    WORKING PRINCIPLE Volatile substances can effectively be removed from a liquid such as wastewater or drainage water. This is accomplished in the Galicos system by evaporating them in the relatively large gas (air) flow that is intensively brought into contact
  • Recovery of thermal energy
    Galicos - Uitwisseling:Terugwinning van thermische energie
    WORKING PRINCIPLE In the first Galicos module, the recirculating gas stream absorbs evaporation heat and some (clean) vapor from the contaminated hot fluid. In the second Galicos module, this gas stream condenses in the cooler and cleaner liquid and the
  • Distilation
    Galicos - Destillatie van vloeistoffen
    WORKING PRINCIPLE In the first Galicos-module (the evaporator) the liquid is led as a thin film shaped stream at increased temperature over a number of inclined plates. These plates are equipped with a large amount of specially shaped openings which
  • Aeration of liquids
    Galicos - Beluchting van vloeistoffen
    WORKING PRINCIPLE A liquid can effectively be aerated through one or more Galicos modules (see w principle). Depending on circumstances the oxygen transfer is around 3 to 4.5 kg of oxygen per KWh of energy consumed. Features Low costs Not
