ResinTech SIR-110-HP, Perchlorate Removal Anion Resin, Cl Form, 1 Cubic Foot
ResinTech SIR-110-HP is a chloride form nitrate and perchlorate selective strong base anion resin. SIR-110-HP has unique functionality that greatly increases selectivity for nitrate while greatly decreasing the interference from sulfate ions. SIR-110-HP has the highest possible selectivity for perchlorate when compared to other similar resins. SIR-110-HP is intended for all perchlorate removal applications, and where the highest possible affinity for nitrate is desired.
Features & Benefits
- High Operating Capacity Of Any Perchlorate Selective Resin: Highly Selective for perchlorate and nitrate
- Low Sulfate Selectivity: The unique functional group eliminates the possibility of nitrate dumping
- 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:
- Perchlorate Removal: ResinTech SIR-110-HP is ideal for single use perchlorate removal applications and is a cost effective method to remove trace levels of perchlorate from water. The perchlorate ion is very strongly attracted to the Resin, so much so that regeneration is impractical or impossible. However, in most cases perchlorate loads to almost the full capacity of the resin, resulting in very long service life and eliminating the need to regenerate and re-use the spent resin.
- Nitrate Removal: SIR-110-HP can be used in the chloride form to remove nitrates as well as perchlorates from potable water. SIR-110-HP has higher capacity for nitrate that SIR-100-HP in high TDS waters. When treating waters with high hardness the brine dilution and displacement waters should be softened and a low hardness salt used to prevent scaling.
- Iodide Removal: SIR-110-HP has much higher selectivity for iodide than other strong base anion resins (about 7 to 10 times higher). This high selectivity allows for single use removal of iodide against rather high concentrations of other ions with reasonable throughput capacity. Regeneration, although possible, is complicated and cannot be accomplished with salt or other common regenerants.
- Pertechnetate Removal: SIR-110-HP has similar affinity for pertechnetate as for perchlorate and can be used to remove trace levels of pertechnetate effectively over a very wide range of TDS and bulk ion compositions. Throughput capacities in the tens of thousands of bed volumes are typical.
