Get Chemical-Free Filtering with One of Our Iron Filters

If you want to filter your water without chemicals, Alberta Aqua-Tech Ltd can help supply you with one of our iron filters in Edmonton.

Once installed, the chemical-free iron filter requires little or no attention. It automatically removes soluble iron, sometimes called ferrous iron or “clear water,” and precipitated iron, sometimes called ferric iron or "red water."

It is safe and very economical because it requires none of the expensive or messy chemicals conventional iron filters use. The chemical-free iron filter features two major components: an air injector and a back washable filter containing Birm® media. In some applications, a contact tank or an additional pressure tank may be required for the iron filter 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 iron changes into a colloidal state, and as such, it is trapped throughout the filter bed.

The chemical-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 four to 12 days, depending on iron concentration and water usage.
