Many thanks.

This will sound a dumb question, but in your expert opinion would you every expect say CWS62 media to ever wear or reduce in size enough to pass through the 1.4 sieve as good media (this does not include broken media)? And subsequently the same for the other 2 medias?

The reason for my question is if it is possible that would then mean the this media would obviously fail against its original requirements but then would be to large to be reclassified as the next media (as it wouldnt pass through its top sieve) and so would require removing from the process and be scrap.
