Adjustment of lime-carbonic acid equilibrium to protect systems and infrastructure Natural water contains, in addition to various dissolved minerals, bound and free carbon dioxide. The lime-carbonic acid equilibrium of water refers to the chemical balance between the ions of calcium carbonate and carbonic acid. If water contains less carbon dioxide, it is lime separating; if it contains more, it is lime soluble. The production or maintenance of the lime-carbonic acid equilibrium prevents: Calcification of closed pipelines by the precipitation of calcium carbonate (limestone) with an insufficient content of free associated carbonic acid Damage to metallic equipment components or pipelines by an excess of aggressive free carbonic acid Deacidification is the reduction of the concentration of the carbon dioxide dissolved in water by outgassing or reaction with basic substances. It leads to an increase in the pH value in the water. In the Drinking Water Ordinance of 2011, the respective limit values are specified as pH between 6.5 and 9.5 Lime solubility capacity less than 5 g/m³; this requirement is met starting with a pH of 7.7 With our proven desorption systems, spring, well and surface water is deacidified and filtered according to the principle of lime-carbonic acid saturation. Carbon dioxide is extracted from the raw water and transferred into the gas phase. The deacidification performance can be adjusted by adapting the quantity of blown gas to changing requirements.
