This is a high-capacity, bead-form, conventional gel polystyrene sulfonate cation exchange resin ready for use in household or industrial water conditioning equipment. It removes hardness ions, e.g. calcium and magnesium, replacing them with sodium ions. When the resin bed is exhausted so that the hardness ions begin to break through in the effluent, capacity is restored by regeneration with common salt. NOTE: The capacity obtained depends largely on the amount of salt used in the regeneration.

Below are common tanks sizes with the typical amount of resin used in them.

9"x48" Tank - 1 cubic foot - 32,000 grain

10"x54" Tank - 1.5 cubic feet - 48,000 grain

12"x48" Tank - 2 cubic feet - 64,000 grain

13"x54" Tank - 3 cubic feet - 96,000 grain
