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 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.
Colloidal and inorganically bound iron is of ferric or ferrous form that will not filter or exchange
out of water. This water softener will not remove colloidal iron. In some instances, treatment may
improve colloidal iron water. 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.
3. Acidity or acid water is caused by carbon dioxide and hydrogen sulfide. This water softener will
not improve an acid condition in water. Acid water can be corrosive to plumbing, plumbing
fixtures, water heaters, and other water using appliances. In 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.
4. Sediment is fine, foreign material particles suspended in water. This water softener will not
remove sediment. This material is most often clay or silt. Extreme amounts of sediment may give
the water a cloudy appearance. A sediment filter installed ahead of the water softener normally
corrects this situation.
