Do You Have Iron Present In Your Source Water?

Is Iron present in your source water? High levels of Iron can cause premature wear on equipment, discoloration and staining, as well as being harmful to your irrigation system and plants. In most cases when Iron (FE) is present, manganese (MN) will be as well. With the I-Series Filtration Systems from Everfilt®, we can effectively remove or significantly reduce these elements to undetectable levels as low as 0.001 ppm and manganese to 0.001 ppm.

DMI-65® is a granular material of dark brown to black color. This color is produced by the manganese oxide in the outer layers of the granules. DMI-65® is a catalytic media in the true meaning of the word and facilitates oxidation—precipitation-filtration and does not get consumed in the reactions.

The media does not need regeneration or reactivation and does not display a decaying capacity to do its catalytic work. Over a 5 to 10 years period, through many backwashing operations of the bed to remove retained solids, the media is degraded by contact between particles and mechanical abrasion. Then the material has to be replaced. In order to begin the process of oxidation of the ions in solution and to ensure that the oxidative layer is not compromised, the media is designed to operate in the presence of chlorine or other oxidants.

In this process, the oxidant removes electrons and is consumed in the process. The operator needs to ensure that there is a 0.1 - 0.3 PPM free chlorine residual in the effluent water.

BENEFITS OF AN EVERFILT® I-SERIES FILTRATION SYSTEM

• Multiple system sizes and configurations to accommodate flows from 15 GPM to 4500 GPM.
