INSTALLING WATER SOFTENERS ON
WATER SUPPLIES CONTAINING IRON
Iron is a common water problem. The chemical/physical nature
of iron found in natural water supplies is exhibited in four
general types:
1. Dissolved Iron
Also called clear water iron. Up to 2 ppm of this type of iron can
be removed from the water by the same ion exchange principle
that removes the hardness elements, calcium and magnesium.
Dissolved iron is soluble in water and is detected by taking a
sample of the water to be treated in a clear glass. The water in
the glass is initially clear, but on standing exposed to the air, it
may gradually turn cloudy or colored as it oxidizes.
2. Particulate Iron
Also called ferric or colloidal iron. This type of iron is an
undissolved particle of iron. A softener will remove larger
particles, but they may not be washed out in regeneration
effectively and will eventually foul the ion exchange resin. A
filtering treatment before the water softener will be required to
remove this type of iron.
3. Organic Bound Iron
This type of iron is strongly attached to an organic compound
in the water. The ion exchange process alone cannot break this
attachment and the softener will not remove this type of iron.
4. Bacterial Iron
This type of iron is protected inside a bacteria cell. Like the
organic bound iron, it is not removed by a water softener.
When using a softener to remove both hardness and up
to 2 ppm of dissolved iron it is important that the softener
regenerates more frequently than ordinarily would be
calculated for hardness removal alone. Although many factors
and formulas have been used to determine this frequency, it
is recommended that the softener be regenerated when it has
reached 50–75% of the calculated hardness alone capacity. This
will minimize the potential for bed fouling.
If you are operating a water softener on clear water iron,
regular resin bed cleaning is needed to keep the bed from
coating with iron. Even when operating a softener on water with
less than the maximum of dissolved iron, regular cleanings
should be performed. Clean every six months or more if iron
appears in your conditioned water supply. Use resin bed
cleaning compounds, carefully following the directions on the
container.

LOCATION SELECTION

1. If you need extra water treatment equipment, make sure
space is available.
2. Since salt must be added to the brine tank, make sure that
the lid can easily be opened.
3. Install softener in a location to allow a minimum of 10 feet of
piping between the outlet of the softener and the inlet side
of the hot water heater.
