Purolite® MB400IND
Mixed Bed Exchange Resin -
Self Indicating
Purolite MB400IND is a high
quality resin mixture for direct purification
of water. This resin mixture changes color
from blue-green to amber on exhaustion.
It is designed for use in both regenerable
and non-regenerable cartridges. It contains
an indicator which shows when the resin
is exhausted and can no longer treat the
water. The chromatographic profile is sharp
when using standard flow rates of 5-40 BV/h,
hence a sharp color change is observed and
moves progressively down the bed as the
resin is exhausted. Passage of water at
recommended flow rates through the resin,
as supplied, can achieve almost complete
reduction of total dissolved solids. The
residuals produce average conductivity values
of about 0.1 µS/cm for a major portion
of the service run. However it will be necessary
to cease water production shortly prior
to complete color change if highest quality
water is essential. Generally water with
a conductivity between 5-30 µS/cm
is obtained when the green-blue color finally
disappears. Exposure of the mixture to the
atmosphere for lengthy periods can result
in some loss in hydroxide sites of the anion
component by conversion to carbonate from
carbon dioxide in the atmosphere. This can
give rise to loss of treated water quality.
Exposure of the resin to daylight can also
result in loss of indicator color. Accordingly
the resin should be loaded into the cartridges
as soon as possible after opening the bags,
and any unused resin repacked in airtight
packaging which is impervious to daylight.
