Purolite® MB450VC

Mixed Bed Exchange Resin - Self Indicating

Purolite MB450VC is a resin mixture for direct purification of water of the highest quality. This resin mixture changes color from emerald green to deep blue 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 colour change if highest quality water is essential. Generally water with a conductivity between 5-50 µS/cm is obtained when the blue colour 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.
