Purolite® MB500
Mixed Bed Exchange Resin
Purolite MB500 is a resin mixture for direct
purification of water of the highest quality.
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 less than
0.1 µS/cm for a major portion of the
service run. If there is a use for water
of slightly lower quality for some purposes,
the run can often be extended to offer an
extra throughput depending upon the concentration
of bicarbonates in the feed water. Generally
water with a conductivity between 1-50 µS/cm
is obtained for a useful period where bicarbonate
content in the inlet water is quite high.
It should be noted that at the end of the
run, when the bed is exhausted, water of
low pH (less than 4) 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.
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.
