Purolite Resin

We offer purolite resin. Purolite c100 is a premium industrial grade, gel polystyrenic strong acid cation exchange
resin, supplied in the sodium form. Its principal application in the sodium form is in industrial
water softening. Due to its robust nature purolite c100 is also used as a cation exchanger in
demineralization plants, where it is operated in the hydrogen form following full acid
regeneration.
This document refers specifically to the resin use in water softening, for the removal of total
hardness, with sodium chloride (salt) regeneration. For its use as cation exchange resin in
demineralization processes, please refer to the purolite c100 hydrogen cycle engineering
bulletins.
Purolite c100 has a standard particle size distribution and it is primarily used in co-flow and
traditional counter-flow regenerated softening units. It operates successfully over a wide range
of operating conditions and it offers a higher resistance to the attack by oxidizing agents, such
as chlorine, compared to some other less robust softening resins, resulting in a longer resin life.
