Nelsen Corporation & Purolite Resins
Nelsen Corporation Resins
High cross-linked styrene divinylbenzene strong acid cation resin in bead form. Specially developed to eliminate taste and odor and
provide excellent stability. It is primarily used for softening water in municipal and industrial water treatment. 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.

Purolite Standard
Purolite Standard Resin is a high purity premium grade bead form conventional gel polystyrene sulfonate cation exchange resin designed
expressly for the treatment of foodstuffs, beverages, potable waters, and water used in the processing of food. Its specification is
such that it will exceed the relevant EEC requirements, and the resin is in compliance with the U.S. Food & Drug Administration Code
of Federal Regulations section 21, paragraph 173.25; for use in the treatment of foods for human consumption. Its high bead integrity,
excellent chemical and physical stability, and very low extractables content play a large part in its successful employment in these areas.
