| Many industries need large
quantities of softened water. This is mainly important in cooling water for
circuits and boilers, to prevent the formation of scale. Most process
water preparation techniques include the addition of lime milk. By precipitating
the bicarbonates dissolved in the water, this cost-effective treatment softens
the water, restricting the formation of scale. The chemical reaction is:
Ca(HCO3)2 dissolved + Ca(OH)2 -> 2CaCO3 insoluble + 2 H2O
Lhoist has developed special qualities of lime milks, particularly suited
to decarbonisation.
