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.
