- Once installed, the chemical free iron filter requires little or no attention. It
automatically removes soluble iron, sometimes called ferrous iron or “clear
water”, precipitated iron, sometimes called ferric iron or “red water” and
bacterial iron. It is safe and very economical because it requires none of the
expensive or messy chemicals conventional iron filters use.
The chem-free iron filter features two major components, an air injector and a
backwashable filter containing special media. In some applications a contact tank or an
additional pressure tank may be required for the chem-free to function.
The air injector adds a controlled amount of air to the water supply just before it enters
the pressure tank. The air starts the iron removal process as the water sits in the tank.
The water’s pH is automatically raised to neutral or higher as it passes through the filter
bed and a catalytic effect occurs between the iron and filter media. The iron changes
into a colloidal state and is trapped throughout the filter bed. This produces an iron
removal capacity four times greater than a conventional iron removal filter.
The chem-free filter media remains unchanged at the end of the oxidation process and
consequently requires no chemical regeneration.
Periodic backwashing of the filter bed flushes the precipitated iron to the drain and readies
the filter for use again. The duration and frequency of backwashing varies from 10 to 12
minutes every 4 to 12 days, depending on iron concentration and water usage.
Neutralizes acidic water
The chemical free iron removal filter’s patented process raises the pH of the water, improving
the efficiency of iron removal. This has the added benefit of neutralizing acidic water.
