Adjustment of the Lime/CO2 Balance |
| Water has the right balance of carbon dioxide (CO2) and lime when it neither dissolves nor precipitates calcium carbonate (insoluble lime). If there is an imbalance, water causes either corrosion due to aggressive carbon dioxide or calcification of pipelines and fittings etc. due to lime precipitation.
The lime/CO2 balance is defined by a specific pH value. The application of carbon dioxide is an effective method of accurately adjusting this value. This process is particularly useful in connection with the following:
- Limestone-precipitating water
- Water following rapid decarbonisation with lime milk
- Water after stripping
Our solution
SOLVOCARB® resolves the lime/CO2 balance by injecting carbon dioxide into water. The following two injection methods are available:
- SOLVOCARB®-D: CO2 injection using a spherical-head nozzle
- SOLVOCARB®-R: CO2 injection using reactors
Advantages of applying carbon dioxide instead of mineral acids
- Highly accurate adjustment of pH value
- Carbon dioxide is a natural water compound (mineral acids are not)
- Drinking water tastes better
- No corrosion as a result of aggressive mineral acids
- No safety worries associated with handling aggressive mineral acids
