Purolite® MB500VC
Mixed Bed Exchange Resin - Self Indicating
Purolite MB500VC is a resin mixture for
direct purification of water of the highest
quality. This resin mixture changes color
from emerald green to amber/opaque on exhaustion.
It is suitable for use in regenerable or
non-regenerable cartridges or in large ion
exchange units. 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 prior to complete color
change if highest quality water is essential.
Generally water with a conductivity between
5-50 µS/cm is obtained when the blue
color reaches close to the bottom of the
bed. It should be noted that at the end
of the run, water of low pH can be produced.
Equivalent volumes of pure water may be
obtained after regeneration but only if
sufficient regenerant quantities are employed
to achieve the percentage conversion levels
close to those of the "as supplied"
resin. Generally acceptable capacity and
quality is obtained economically at lower
regeneration levels. Self indication may
only be possible for several cycles. Exposure
to the atmosphere even for less than one
hour can produce a noticeable difference
in treated water quality when the purest
water quality obtainable is required. Exposure
for long periods can result in carbonation
of the anion resin which results in substantial
loss of performance. Hence once packaging
is opened, resin should be used directly,
and any unused resin returned to containers
and sealed.
