WATER CONDITIONER BASICS
WHAT IS HARD WATER AND HOW IT IS SOFTENED
All of the fresh water in the world originally falls as rain,
snow, or sleet. Surface water evaporates and is drawn
upward by the sun, forming clouds. Then, nearly pure and
soft as it starts to fall as rain. It begins to collect impurities as
it passes through smog and dustladen atmosphere back to
the ground. And as it seeps through soil and rocks it gather
hardness, rust, acid, unpleasant tastes and odors.
Water hardness is caused primarily by limestone dissolved
from the earth by the rainwater. Because of this, in earlier
times, people who wanted soft water collected rainwater
from roofs in rain barrels and cisterns before it picked up
hardness from the earth.
Some localities have corrosive water. A softener cannot
correct this problem. This softner has warranty disclaims of
liability for corrosion of plumbing lines,fixtures or appliances.
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 calqled ferrous or “clear water”
iron. 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. This type of iron can be removed from the
water by the same ion exchange principle that removes the
hardness elements, calcium and magnesium.
2. PARTICULATE IRON —Also called ferric or colloidal
iron. This type of iron is an undissolved particle of iron.
A filtering treatment will be required to remove this
type of iron. A softener will remove larger particles, but
the particles may not be washed out in regeneration
effectively and will eventually foul the ion exchange
resin.
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 bond down
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.
It’s important that when a softener is removing both
hardness and dissolved iron, it must regenerate more
frequently than it normally would for just hardness.
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.
Regular resin bed cleaning is needed to keep the bed
from coating with iron if you are operating a water
softener on clear water 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 often if iron appears in
your conditioned water supply. Use resin bed cleaning
compounds carefully following the directions on the
container.
CAUTION
DO NOT USE WATER FILTERED THROUGH THIS SOFTENER WHERE THE WATER
IS MICROBIOLOGICALLY UNSAFE OR THE WATER IS OF UNKNOWN QUALITY.
THE WATER MUST BE DISINFECTED BEFORE OR AFTER THE UNIT.
