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. The capacity obtained depends largely on the amount of salt used in the regeneration. This resin is also capable of removing in the same way dissolved iron, manganese, and also suspended matter by virtue of the filtering action of the bed. This resin is in compliance with the U. S. Food and Drugs Code of the Federal Regulations section 21 paragraph 173.25.
