Total or semi-removal of carbohydrate-ions (HCO3-) through weak acid cation-exchange material.
Calcium and magnesium are removed from the water and replaced through H+-ions.
The hydrogen-ions released and the carbohydrates remaining
react into H2O and CO2, which can be ejected over a CO2-rippler.
A softening and decarbonization takes place by way of such a semi removal of salt.
