Purolite® UCW1080, Low TOC Boron Selective Weak Base Anion Resin, Free Base Form is a macroporous polystyrenic based resin, with functional groups specially designed for the selective removal of boron from ultrapure water.

UCW1080, in the free base form, is used as a separate anion bed in the ultrapure water loop in between the primary and final polishing mixed beds. If a UV system is installed in between the two mixed beds, UCW1080 should be installed just ahead of the UV system. UCW1080 is effective over a wide range of pH values and boron concentrations. Even where the concentrations of other ions are high, UCW1080 will reduce boron concentrations by an order of magnitude.

Efficiency of removal of boron is flow dependent so guidelines for specific flow rates and minimum bed depth should be strictly followed to achieve consistent performance.

With the low concentrations of boron typically found in ultrapure water systems, it is usual for UCW1080 to be operated for several years before its capacity for boron is exceeded. Therefore, under such circumstances, regeneration of UCW1080 is not recommended.
