CATION Standard and Fine Mesh Resins

CATION Standard and Fine Mesh resin is a highcapacity, 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 ft3 is used to obtain maximum capacity of
up to 33,000 grains per ft3.
