EShore Ironmax
IRONMAX is made of durable and special materials with high-quality manganeseand have gone through multi-mixing and refining processes; it is capable of effectively removing/oxidizing dissolved iron ions in underground water.

Fe2+ found in raw water can be absorbed by sodium form cation exchange resin. Whereas, the Na+ form cation exchange resins are regenerated by NaCl, but Na+ cannot help to replace Fe2+ which were absorbed in cation exchange resin then further causes a shortened resin regeneration cycle. This condition is called Iron Fouling.

IRONMAX is also characterized by porosity and this leads to an additional benefit of removing suspended solids from water.

With iron remover media, catalytic/ adsorption reaction is able to extend operating time and decrease backwash frequency.

Reaction Formula:


catalyst (filter media): FeOOH
Fe2+ + FeOOH-->FeO(Fe)++ H+
2Fe2++1/2 O2+ 5H2O-->2FeOOH
H2O + 4CO2
