  5. Low-pressure Carbon Dioxide (CO₂) dissolver in FRP

Low-pressure Carbon Dioxide (CO2) dissolver in FRP

The desalinated water, due to its characteristics, it does not usually contain enough CO2 for a correct remineralization. DrinTec™ low-pressure CO2 dissolvers solve this problem by maximising CO2 dissolution without overdosing. Partial or complete pre-treatment with CO2 prior limestone contactors can be done.

The low-pressure CO2 dissolver system consists of the following elements:

  1. The dissolver tank, that operates under the following conditions:
    • The CO2 is dosed at counter-current
    • Water velocity inside the dissolver is such that the bubbles are not dragged away
    • The tank is pressurized
    • Has a special CO2 diffuser that provides very fine exudation in a very large diffuser area.
    • The dissolver has internal devices that facilitate the mixing of CO2 microbubbles.
    • Made with materials and adhesives approved for use in drinking water.
  2. The CO2 diffuser, that has the following characteristics:
    • Large diffusers with fine pores and minimal differential pressure requirement.
    • The distance between the pores of the diffuser allows an even distribution of the micro-bubbles.
    • It has a design that allows the application of substantial quantities of CO2.
    • Made with materials and adhesives approved for use in drinking water.
  3. The bubble visor:
    • Located at the same height as the diffusers to check a correct operation.

This development is based on a joint research project between the FCCA and the S.G. Of Water of Barcelona financed by the European Union.
