Q1: What is the primary functional form of AMBERLITE IR 120 NA resin?
A: AMBERLITE IR 120 NA is supplied in the sodium (Na⁺) form, making it suitable for softening applications where calcium and magnesium ions are exchanged for sodium ions in aqueous streams.
Q2: Can IR 120 NA be used in food-grade or potable water treatment systems?
A: Yes — when operated and regenerated according to applicable regulatory guidelines and manufacturer recommendations, IR 120 NA is commonly employed in food processing, beverage production, and municipal or residential drinking water softening systems.
Q3: How is the resin regenerated after exhaustion?
A: Regeneration is typically performed using a brine solution (sodium chloride), which restores the resin’s exchange capacity by displacing accumulated hardness ions with sodium ions. Regeneration efficiency depends on brine concentration, flow rate, contact time, and bed depth.
Q4: Is IR 120 NA compatible with high-temperature process streams?
A: The resin is designed for operation at ambient to moderately elevated temperatures; continuous use above 120 °C is not recommended, as thermal degradation may reduce capacity and mechanical stability over time.
