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.
