Water purification of iron ions

A high content of iron ions in tap water is one of the most extended problems connected with quality of water for drinking and general-use purpose.

Iron ions contained in water are not only toxic for human but also they exercise a negative influence on water supply systems (pipe lines, shutoff and control valves), household devices and dishes.

Ion exchange materials PANION® purify water effectively both of ions of dissolved iron Fe2+, and oxidized iron Fe3+.

Materials PANION intended for water purification of iron ions

Panion 110 — removal of iron ions, water softening

Fibrous ion exchanger PANION 110

PANION 110 — weak-acid fibrous cation exchanger, an analogue of well-known trademarks VION, FIBAN, MION.

Applications:

  • Air purification from volatile substances of base nature: ammonia, amines, alkalis etc. Panion 110 can be applied in industrial and domestic air cleaning systems;
  • Water purification from the ions of heavy metals, water softening;
  • Human protective means (respirators, gas-masks, protective costumes etc): removal of vapors of ammonia and amines.
