Natural calcium carbonate neutralisation  

Akdolit® C (Hydro-Carbonate) is a natural pure limestone. It is used for the neutralisation of soft or aggressive water by filtration in order to meet the requirements of the Drinking Water Ordinance. In this process, an increase of the concentration of the calcium and hydrogen carbonate ions is achieved, which is favourable to prevent corrosion.
