ResinTech SIR-100-HP, Nitrate Removal Resin, Cl Form, 1 Cubic Foot
ResinTech SIR-100-HP is a chloride form macroporous nitrate selective strong base anion resin. SIR-100-HP has unique functionality that increases selectivity for nitrate and decreases selectivity for sulfate. This results in higher operating capacity, lower leakage, and freedom from nitrate dumping if operated past sulfate break. SIR-100-HP is intended for all nitrate removal applications, and can be used also to remove perchlorate.
Features & Benefits
- High Operating Capacity And Efficient Brine Regeneration: Unique amine functional group provides the highest possible operating capacity
- Low Sulfate Selectivity: Eliminates the possibility of nitrate dumping
- Superior Physical Stability: 95% 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:
- Nitrate Removal: ResinTech SIR-100-HP is used in the chloride form to remove nitrates from potable water. It has a unique amine functional group that eliminates the possibility of nitrate dumping. SIR-100-HP has reduced affinity for sulfate which provides high operating capacity and efficient regeneration. When treating waters with high hardness the brine dilution and displacement waters should be softened and a low hardness salt used to prevent scaling.
- Perchlorate Removal: SIR-100-HP can be used for the removal of perchlorate from groundwater supplies. The perchlorate ion is so strongly attracted that in some cases it makes regeneration impractical.
- Perchlorate Removal: SIR-100-HP can be used for the removal of perchlorate from groundwater supplies. The perchlorate ion is so strongly attracted that in some cases it makes regeneration impractical.
