United Water Inc. CR Series Media
CR 26
Iron, Manganese, Hydrogen Sulfide and Arsenic Removal Media
CR 26 is a special media designed to provide excellent catalytic properties required for removal of many contaminantsfrom
potable and non-potable aqueous streams. CR 26 is an insoluble media that oxidizes species in solution includinghydrogen
sulfide, iron and manganese. Metal-oxide nano-particles are precipitated within the resin bed where they form very strongchemical
bonds with arsenite (As III) and arsenate (As V). This allows CR 26 to thoroughly and effectively remove arsenicalong with Fe, Mn
and H
S.

Packing
CR 26 is supplied in 1 cubic foot poly bags.
Storage
Resins require proper care at all times. The resinsmust
never be allowed to dry. Recommended storage
temperature is between 65°F to 110°F.
Safety Information
CR 26 is not a hazardous product and is not WHMIS
controlled.
Caution: Acidic and basic regenerant solutions are corrosive and should be
handled in a manner that will prevent eye and skin contact. Before using
strong oxidizing agents in contact with ion exchange resin, consult sources
knowledgeable in the handling of these materials.

CR 26 was initially designed for the selective removal of
iron and manganese but testing has shown the product

to be ideal for multi-contaminant removal. Seepage 3 of
this bulletin for a summary of various tests performed to
date.
Expected Service Life
Due to the unique nature of CR 26 and its functionas an
oxidizing agent encapsulated within an ion exchangebead,
a long service life of 7 to 10 years is expected.
