High TDS (Total Dissolved Solids) water requires a specific resin for softening. Ion exchange resins, often strong acid cation exchange resins, are commonly used. These resins exchange hardness ions (e.g., calcium, magnesium) for sodium ions, effectively softening the water. The resin beads need periodic regeneration with brine (a concentrated salt solution) to maintain their softening capacity.
