Nitrate Removal

Nitrate Removal

Reverse Osmosis

  • Use Thin-Film - Composite Membranes
  • 80% Removal
  • High concentrations of sodium or sulfate will reduce nitrate removal
  • Low pH will reduce nitrate removal

Ion Exchange

  • Anion Resin
  • 3 - 12% Salt (Sodium Chloride) used for regeneration
  • Nitrate may leak through the resin if the resin is exhausted beyond the "Breakthrough" point. Treated water may contain up to 3 times the incoming nitrate concentration.
