DESCRIPTION:
Cationic and anionic resins for efficient metal and ion removal
Cation and anion exchange resins for softening, dealkalization, nitrate removal and selective metals capture, or as mixed‑bed polishers post‑RO.
STANDARD SPECIFICATION:
– Types: SAC, WAC, SBA, WBA, chelating (iminodiacetate/aminophosphonic)
– Operating forms: H⁺/Na⁺ (cation), Cl⁻/OH⁻ (anion)
– Service velocity: 5–40 BV/h; bed depth 0.8–1.2 m; temp ≤ 60 °C typical
– Regenerants: NaCl, HCl/H₂SO₄ (cation); NaOH/NaCl (anion)
INDUSTRY USE CASES:
– Groundwater nitrate control; boiler/RO softening
– Selective metals capture; mixed‑bed polishing
PRETREATMENT / INTEGRATION NOTES:
