IRON
in water can cause stains on clothing and
plumbing fixtures. It can negatively affect the taste
of food, drinking water, and other beverages. Iron in
water is measured in parts per million (ppm). The to-
tal* ppm of iron, and type or types*, is determined by
chemical analysis. Four different types of iron in wa-
ter are:
¡
Ferrous (clear water),
©
Ferric (red wa-
ter),
¢
Bacterial and organically bound iron,
£
Col-
loidal and inorganically bound iron (ferrous or ferric).
Ferrous (clear water) iron is soluble and dissolves in
water. This water softener will reduce moderate
amounts of this type of iron (see specifications).** It
is usually detected by taking a sample of water in a
clear bottle or glass. Immediately after taking, the
sample is clear. As the water sample stands, it grad-
ually clouds and turns slightly yellow or brown as air
oxidizes the iron. This usually occurs in 15 to 30 mi-
nutes.
When using the softener to reduce Ferrous (clear
water) iron , add 5 grains to the hardness setting for
every 1 ppm of Ferrous (clear water) iron. See “Set
Water Hardness Number” section.
Ferric (red water), and Bacterial and organically
bound irons are insoluble. This water softener will
not remove ferric or bacterial iron. This iron is visible
immediately when drawn from a faucet because it
has oxidized before reaching the home. It appears
as small cloudy yellow, orange, or reddish sus-
pended particles. After the water stands for a period
of time, the particles settle to the bottom of the con-
tainer. Generally these irons are removed from wa-
ter by filtration. Chlorination is also recommended
for bacterial iron.
Colloidal and inorganically bound iron is of ferric or
ferrous form that will not filter or exchange out of wa-
ter. In some instances, treatment may improve col-
loidal iron water, but always CONSULT A QUALI-
FIED WATER CHEMISTRY LAB before attempting
to treat it. Colloidal iron water usually has a yellow
appearance when drawn. After standing for several
hours, the color persists and the iron does not settle,
but remains suspended in the water.
Iron in water causes stains on clothing and plumbing
fixtures. It negatively affects the taste of food, drink-
ing water, and other beverages.
*Water may contain one or more of the four types of
iron and any combination of these. Total iron is the
sum of the contents.
**Capacity to reduce clear water iron is substan-
tiated by WQA test data.
