To increase the degree of retention by divalent iron, it is necessary to establish a pre-filter "SVOD" - an oxidizing one.

The first filter stage:
The oxidizing filter "SVOD" is a polypropylene cartridge with increased hydrophilicity (processed with singlet oxygen). Removes mechanical impurities, sand, rust, silt, scale, large suspended particles to further activate the surface of the filter.
The resource depends on the composition of the source water and in case of loss of capacity, as a result of scraping (clogging) of iron compounds and other suspended particles, it is necessary to replace it.

Specifications:
Resource - up to 6 months
Size, inch - 4,5 * 20

Second filter stage:
Filter with cartridge "SVOD" De-ironing - is designed to purify water from dissolved and dispersed (insoluble) in water iron compounds. Improves the color, smell and taste of water.

STRUCTURE OF CARTRIDGE
Filtering is carried out in three stages:
The first stage is the removal of cations of polyvalent metals (Ca, Mg, Fe, etc.);
The second stage is a filter for coarse purification and postoxidation of Fe (II) to Fe (III). When water passes through the fiber, iron compounds dissolved and dispersed in water are removed. The fiber is processed to form a complex of functional groups on its surface that ensure maximum extraction of iron compounds (iron oxides, iron salts, etc.).
The third stage is a mechanical fine filter with increased hydrophilicity. Thanks to the additional activation of the surface of the filter, the fine fine particles and other mechanical impurities are pre-trapped.
