Purpose

The mixed bed was developed to provide an integrated solution to the problems in water treatment systems. It is efficient in removing iron and manganese ions as well as hardness.

Description

The media is a specially selected mixture of ion-exchange resins with the addition of fractionated natural minerals and a polymer.

Equivalents

The equivalents are the mixed bed ion-exchange media Ecotar B, Ecotar B30, Ecomix P etc.

The requirements for raw water

pH range Up to 14 pH
Total iron Up to 25 mg/l
Manganese Up to 5 mg/l
Total hardness Up to 15 mg-eq./l
Permanganate oxidation Up to 4 mg O2/l
Hydrogen sulphide none

Recommendations for use

Upon loading the tank, back washing is recommended for 5 minutes to develop laminarity.

In case of high concentrations of ferric (above 5 mg/l) in the raw water as well as for extending the media service life, the antibacterial resin purifier should be used once every 2-5 regenerations.

In case of a large media volume, a smell may appear, which does not affect the water quality. If the smell still persists and is unwanted, it is recommended to perform regeneration and leave the tank loaded with the media for 24 h, subsequently repeating the regeneration. The smell will disappear after a while.

The formula for approximate calculation of the filtration cycle: V = (1.2 * VFS) / (G + 2 * СMn + 1.37 * СFe)

V - filtration cycle, m3

VFS - volume of Fero Soft, l

G - total hardness of raw water, mg.-eq./l

СFe - iron concentration in raw water, mg/l

СMn -manganese concentration in raw water, mg/l

*The formula provides an approximate indication of the actual filtration cycle. The most optimal is the experimental selection of the period between regenerations and washing time, which enables using the water treatment system at minimal consumption of regenerate and washing water.

Service life of the media is up to 5 years.
