IF-3 Inert Resin


IF-3 is an inert polymer in the form of cylindrically shaped for use as covering.

IF-3 is of lighter specific gravity than water and therefore it floats on the surface of ion exchange resin bed.

The polymer has both optimum specific gravity and particle size range which ensure that, during backwashing, it will be positioned between the cation resin which settles to the bottom of the bed and the anion resin at the top. The ability to resist attrition and mechanical stress makes certain that near perfect separation continues cycle after cycle.

Regeneration of the bed may be carried out in situ, or alternatively, resins may be transferred to a separate regeneration system. This latter technique is designed to avoid regenerant contamination of the service lines.
