Specifications:

• Softening Resin, 27 lbs.
• Nelsen brand CATION Standard resin is a high quality, high capacity, conventional gel polystyrene strong acid cation exchange resin designed for use in residential or industrial water softening equipment.
• Cation resin in sodium form removes hardness ions such as calcium and magnesium by replacing them with sodium.
• When the resin bed is exhausted the hardness ions begin to pass through the bed.
• Functionality is returned by regeneration with concentrated sodium or potassium chloride solution.
• The capacity obtained depends largely on the amount of salt used in the regeneration.
• Typically 15 lbs of chemical per cubic foot is used to obtain maximum capacity ofup to 33,000 grains per cubif foot, or more commonly 9 lbs of salt is used per cubic foot to achieve 22,000 grains per cubic foot.
