Softening resins, or for that matter, all ion exchange resins, life is reduced by chlorine in the feed water. Resin life was discussed in detail in PURONEWS - Volume 1 Issue 5 - May 2001. Standard resins such as PUROLITE C100 or C100E can withstand a chlorine residual of 0.2 - 0.5 without a drastic life reduction. At levels of 1 ppm or higher the life will be significantly shortened. Each 1 ppm of chlorine, on a continuous basis, will reduce resin life by one half. Softening resins should have a life of 10 years or more on chlorine free water. We have seen life of over 30 years in many cases. If you have a high chlorine residual in the feed water, it is best to remove the chlorine. Second best is to use a softening resin that has a higher DVB crosslinking.
The primary cause of reduced life on chlorine bearing waters is the chlorine attacks the DVB crosslinking in resin. Where standard softening resins have an 8% DVB crosslinking these resins have from 10% to as much as 20% DVB crosslinking. More DVB means longer resin life.
NOTE: C100E is food grade resin and made in the USA. C100LT is not food grade and is made in China.
