Granulated dolomitic material for fast neutralisation

Akdolit® CM G (Gran) is a highly reactive filter material with a spherical granular form, especially suitable for pneumatic conveying and silo feeding. It is used for the neutralisation of water (by filtering) in order to achieve the calco-carbonic equilibrium and to meet the requirements of the Drinking Water Ordinance. Through this calco-carbonic equilibrium process, an increase in the concentration of the calcium, magnesium and hydrogen carbonate ions is achieved, which is favourable to prevent corrosion.  

Technical information


Akdolit® CM G (Gran) meets the requirements of the standards EN 1018 type 1, EN 16004, drinking water regulation and DIN 2000 (Germany).
