LEWATIT® K 3433

Summary

Product identification

• Product name: Lewatit® K 3433
• Description: Weakly basic, macroporous, palladium-doped, polymer-based resin in spherical bead form.
• Function: Catalytically removes dissolved oxygen from water when a reducing agent (e.g., hydrogen) is dissolved in the water.
• Applications:
  • Removal of dissolved oxygen from water for drinks production.
  • Removal of dissolved oxygen from sea water used in offshore oilfield injection.
  • Oxygen elimination from boiler feed water and heating circuits.
