Mixed Bed Resin
When the pure water coming
out of your DI bottle isn't as pure as it was or
should be and it's time to replace your mixed bed
resin, don't throw away the resin that's in your
bottle.
If your water was originally going into the DI bottle at
say 84 ppm (parts per million) and was coming out at 0 - 2
ppm but is now coming out at over 11 ppm then it's unlikely
that your pure water cleaning system is leaving the windows
you've cleaned, spot free.
By obtaining and using a new DI bottle and new mixed bed
resin, you can continue to use your first DI bottle with
the used mixed bed resin still in it, as a pre-filter for
your second DI bottle.
This means that with two DI bottles instead of one, the
water that is still coming out of your first DI bottle with
a reading of 11 ppm, is what is now going into your second
DI bottle with the new and unused mixed bed resin.
Your second bottle is now only having to clean incoming
water with impurities of 11 ppm instead of with the
original 84 ppm.
This will result in your mixed bed resin in the second
bottle lasting a whole lot longer than your original bottle
lasted.
The savings in having to replace your mixed bed resin less
often, will more than cover the cost of buying your second
DI bottle.
When the water you're using starts to come out of the
second DI bottle at around 11 ppm again, simply use that as
your first bottle and replace the well spent mixed bed
resin in your original bottle with new resin and use this
DI bottle as your second filter.
This system will ensure that the mixed bed resin bottle
that your pure water is coming out of, always has water
going into it at only around 11 ppm instead of 84
ppm.
