Feed water

The product is suitable for purification of water of the highest quality. Passage of water at recommended flow rates through the resin, as supplied, can achieve almost complete reduction of total dissolved solids. Residuals produce average conductivity values of less than 0.1 µS/cm for a major portion of the service run. If water of slightly lower quality is acceptable, the run can often be extended to offer 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.

Product water

• Conductivity (typical average): Less than 0.1 µS/cm for a major portion of the service run.
• Conductivity (with high bicarbonate content in feed): Between 1-50 µS/cm for a useful period.
• End of Run pH: Water of low pH (less than 4) can be produced when the bed is exhausted.

Notes on handling

Purolite MB500 is delivered in sealed, airtight packaging. 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, leading to a substantial loss of performance. Once packaging is opened, resin should be used directly. Any unused resin should be returned to containers and sealed. Equivalent volumes of pure water may be obtained after regeneration, but only if sufficient regenerant quantities are employed to achieve percentage conversion levels close to those of the "as supplied" resin.
