The correlation between specific electrical conductivity and indices of dry residue and hardness was studied in water enriched with macro- and microelements by some methods. A complex correlation was observed between water electrical conductivity and indices of water dry residue and hardness. This correlation depended on the quantitative and qualitative salt composition of the water, which was reflected in the individual group differences between the mean mineralization coefficients that were characteristic of the various salt enrichment methods. Formulas for calculating dry residue and hardness in enriched regenerated water were proposed. These formulas were derived using the group coefficients characteristic of each enrichment method. The conductometric method of qualities of water regenerated from an atmospheric precipitation condensate according to its dry residue and hardness may be used for space flight.
