Purpose

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

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 Ecomix P etc.

The requirements for raw water

pH range Up to 14 pH
Total iron Up to 8 mg/l
Manganese Up to 1.2 mg/l
Total hardness Up to 10 mg-eq./l
Permanganate oxidation Up to 3 mg O2/l
Hydrogen sulphide none

Recommendations for use

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

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

Service life of the media is up to 5 years.
