When a Water Softener is used as an iron remover

A water softener is a fantastic piece of water treatment equipment. If it’s Properly applied, water softeners would remove hardness yielding brighter clothes, remarkeable soap savings, softer hair and skin, etc.

But in many applications, standard water softeners will remove small amounts of Iron. Unfortunately, certain characteristics of the treated water may allow iron to pass right through a water softener staining many fixtures in the home.

If the water softener is used as an remover of Iron, sinks, showers, toilets, and other fixtures in the home may become stained. The pH of the treated water may be the underlying reason.

Iron begins to change it’s showing at pH levels greater than 7.2.

The iron tends to precipitate (becomes a solid) and falls out of solution. This changed “solid iron” or as others refer “ferric iron” may slip right through the water softener. Other types of Iron, such as “Soluble iron” or “ferrous iron” can normally be removed through the ion exchange softening process.

In summary, if the water pH is 7.0 or below then a water softener is a good choice for the removal of hardness in water, and small amounts of iron.

However, if the pH of the water being treated exceeds 7.0, the addition of an iron filter to the system may be necessary to remove iron without damaging the softener and staining of water fixtures in your home.

When choosing an iron filter, a good choice may include such filters that use Green sand Plus or Birm. A Terminator System may also be effective. Filter media’s and systems all have certain capabilities and limitations.
