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:
- The dissolver tank:
- 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.
- The CO2 diffuser:
- Large diffusers with fine pores and minimal differential pressure requirement.
- It has a design that allows the application of substantial quantities of CO2.
- Made with materials and adhesives approved for use in drinking water.
- The bubble visor:
- Located along the wall of the tank as a semitransparent strip, allows to visualize the CO2 that is still in gaseous phase.
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.
