ResinTech SIR-150, Boron Removal Anion Resin, 1 Cubic Foot
ResinTech SIR-150 is a macroporous borate selective weak base anion resin. SIR-150 has unique functionality which makes it extremely selective for borate. ResinTech SIR-150 is intended for all borate removal applications including potable water, ultrapure water, and boron removal from concentrated brine.
Features & Benefits
- Highly Selective for Boron: Able to remove boron from almost any liquid solution, provided that the pH is greater than 4
- Suitable For Regenerable Applications: Two stage acid/caustic regeneration process restores the capacity for hundreds of operating cycles
- Superior Physical Stability: 90% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
- Controlled Particle Size: 16 to 50 mesh size provides a low pressure drop and superior kinetics
- Controlled Particle Size: 16 to 50 mesh size provides a low pressure drop and superior kinetics
Applications:
- Boron Removal From Potable Water: ResinTech SIR-150 can be used to remove boron from potable waters of any type. SIR-150 selectivity for boron is so high that the concentration of common bulk ions such as chloride, sulfate, and bicarbonate are un-important. SIR-150 is kinetically limited an 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 first returned to service to also prevent possible calcium carbonate scaling.
- Boron Removal From Brine: SIR-150 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 concentration salt solution is kinetically hindered by high TDS, therefore flow rates are necessarily low.
- Boron Removal From Ultrapure Water: SIR-150 can be used to remove boron from ultrapure water to sub ppb levels provided that certain precautions are taken. The resin must be completely regenerated to remove bulk ions such as chloride and sulfate, and then rinsed thoroughly with ultrapure water to reduce cation contaminants such as sodium. resin must be ordered as HP grade and pretreated to reduce TOC leaching. The location of the boron removal resin should be in front of the polishing mixed beds so that trace levels of ionic leachables can be removed.
