Deacidification
All naturally occurring water contains free CO2. Free excess CO2 has an aggressive effect on metal and even concrete. The amount of excess carbon dioxide in raw water depends on the hydrogen carbonate and calcium ion concentration, the ionic strength and the temperature of the water.
The amount of excess carbon dioxide in raw water depends on the hydrogen carbonate and calcium ion concentration, the ionic strength and the temperature of the water. To remove excess carbon dioxide from your raw water, we offer various deacidification processes.
Physical processes:
- Flat bed aeration
- Sprinkling
- various other pressureless aeration and deaeration processes
Other chemical processes, such as filtration using special filter media or neutralisation with lye, are also possible.
The right process is selected depending on the conditions and requirements.
Strong acids are e.g. sulphuric acid, nitric acid. Acetic acid or citric acid belong to the weak acids.
