o
Ferric (red water), and Bacterial and organically bound irons are insoluble. 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
suspended particles. After the water stands for a period of time, the particles
settle to the bottom of the container. Generally these irons are removed from
water by filtration. Chlorination is also recommended for bacterial iron.
o
Colloidal and inorganically bound iron is of ferric or ferrous form that will not filter
or exchange out of water. In some instances, treatment may improve colloidal
iron water, but always CONSULT AQUALIFIED 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, drinking
water, and other beverages.
ACIDITY
or acid water is caused by carbon dioxide, hydrogen sulfide, and sometimes
industrial wastes. It is corrosive to plumbing, plumbing fixtures, water heaters, and other
water using appliances. It can also damage and cause premature failure of seals,
diaphragms, etc., in water handling equipment. A chemical analysis is needed to
measure the degree of acidity in water. This is called the pH of water. Water testing
below 6.9 pH is acidic. The lower the pH reading, the greater the acidity. A neutralizer
filter or a chemical feed pump are usually recommended to treat acid water.
SEDIMENT
is fine, foreign material particles suspended in water. This material is most
often clay or silt. Extreme amounts of sediment may give the water a cloudy
appearance. A sediment filter normally corrects this condition.
HOW THE WATER SOFTENER WORKS
SOFT WATER SERVICE, AND REGENERATION
(see illustrations, page 17)
SERVICE
When the softener is providing soft water, it is called “Service”. During service, hard
water flows from the house main water pipe into the softener. Inside the softener resin
tank is a bed made up of thousands of tiny, plastic resin beads. As hard water passes
through the bed, each bead attracts and holds the hardness minerals. This is called ion-
exchanging. It is much like a magnet attracting and holding metals. Water without the
hardness minerals (soft water) flows from the softener and to the house pipes. After a
period of time, the resin beads hold all of the hardness minerals they can and cleaning is
needed to remove them. This cleaning is called regeneration, or recharge. The demand
timer automatically determines when regenerations occur. Regeneration is started at
2:00 a.m. (factory setting) by the softener timer, and consists of five stages or cycles.
These are: FILL, BRINING, BRINE RINSE, BACKWASH, and FAST RINSE.
REGENERATION
o
FILL:
Salt, dissolved in water, is called brine. Brine is needed to clean the
hardness minerals from the resin beads. To make the brine, water flows into
the salt storage area during the fill stage as shown on page 17.
o
BRINING:
During brining, brine travels from the salt storage area, into the
resin tank. Brine is the cleaning agent needed to remove the hardness
