Water purification of heavy metals

Ion exchangers fibrous PANION® are effective filtering materials for removal of heavy metals: Fe(II), Pb(II), Zn(II), Cu(II), Co(II), Ni(II), Cd(II), Hg(II) etc.

Drinking water doesn’t have to contain almost any ions of heavy metals (their maximum allowable concentrations are very small). The most extended problem is removal of ions of ferrous iron (especially in case of using of artesian water). There is also necessary in some cases to remove from drinking water ions of manganese, mercury, lead, cadmium, cuprum, nickel, cobalt, chromium. Natural waters in each particular region contain their own specific set of such of these ions. For example: 1) countries of Eastern Europe - iron and manganese; 2) countries of Western Europe – lead and nickel; 3) big industrial centers – mercury, cadmium, chromium.

It is necessary to preserve during purification of drinking water its natural mineral components essential for human: sulfates, chlorides, bicarbonates, calcium, magnesium and sodium.

Ion exchangers PANION® make it possible to solve this problem.

Panion 110 — Removal of ions of heavy metals, 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.
