| APPLICATIONS: |
Boron Removal From Potable Water
ProSelect Boron/Borate can be used to remove boron from potable waters of any type. Its selectivity for boron is so high that the concentration of common bulk ions — such as chloride, sulfate, and bicarbonate — are unimportant. ProSelect Boron/Borate is kinetically limited and cannot be operated at a high flow rate without experiencing increased leakage and decreased throughput capacity.
Regeneration is accomplished with acid to strip the boron, followed by caustic to remove the acidity. The regenerated resin should be buffered into the potable water range to prevent possible pH excursions when it is first returned to service, and also to prevent possible calcium carbonate scaling. |

Boron Removal From Brine
ProSelect Boron/Borate can be used to remove boron from almost any brine stream, even when the brine is fully saturated. The brine pH must not be lower than approximately 4 or the chelating exchange groups will be destabilized and might not work properly. Ion exchange in any concentrated salt solution is kinetically hindered by high TDS, therefore flow rates are necessarily low. |

Features: |
|
| |
• |
Highly selective for boron — able to remove boron from almost any liquid solution, provided that the pH is greater than 4 |
|
| |
• |
Superior physical stability — 90% plus sphericity, high crush strengths, and carefully controlled particle distribution provide long life and low pressure drop |
|
| |
• |
Suitable for regenerable applications — two stage acid/caustic regeneration process restores the capacity for hundreds of operating cycles |
