An Introduction to Iron

Iron is one of the most common elements found in nature, accounting for at least 5% of the earth’s crust. It is understandable, therefore, that just about all water supplies, surface or ground, contain some measurable amount of iron. In nature, iron usually occurs as an insoluble oxide. Under favorable conditions on the earth’s surface, the iron is converted to a soluble form and becomes dissolved in water with which it comes in contact. For that reason, iron can be found in almost every natural source, but particularly in well waters. Well waters are usually high in carbon dioxide and low in dissolved oxygen and the insoluble iron oxide is converted to the soluble form of ferrous bicarbonate. Ferrous iron is colorless in solution, but when it comes in contact with air, it oxidizes readily creating red, solid particles which are then precipitated as ferric oxide.

Because iron oxidizes readily and precipitates as an insoluble oxide, it will cause staining of laundry and porcelain fixtures. In addition, iron will impart a metallic taste to drinking water and beverages. Where total iron is present at 0.1 ppm it may be considered negligible for domestic use. But, if the total iron level is 0.3 ppm, or higher, it can produce brown/red stains on plumbing fixtures, dishes, cookware, and masonry surfaces. Many commercial applications call for an almost total absence of iron content in process water.

Even at very low levels, iron can produce favorable conditions of the growth of what are commonly referred to as iron bacteria. These organisms (Galionella and Crenothrix) utilize energy obtained from the oxidation of ferrous to ferric iron to “fix” dissolved carbon dioxide into organic molecules necessary for their existence. The growth of these organisms will result in a jelly-like mass, cause pipe incrustation, and can produce foul tasting water. If the interior of a water closet has a gelatinous sludge and the water surface reflects an iridescent (rainbow) slick, it is usually a tell-tale sign of the presence of iron bacteria.

In addition to natural iron content in water, iron can also be placed in solution when corrosion of iron, steel or other metal surfaces occurs. The more corrosive the water, the greater will be the amount of iron and other heavy metals, dissolved from the metallic surfaces with which the water comes in contact. These heavy metals include zinc, cadmium, lead, iron, and copper which often comes from older galvanized and copper piping systems. Where hot water or boiler water is involved under these corrosive conditions, in a home or business location, even higher levels of dissolved heavy metals have been found.

Iron Filters in Greensboro, NC

Nothing separates water treatment dealers more than the methods employed to remediate iron removal. Most of the “new guys” used the old method of “an acid neutralizer for acid, an iron filter for iron, and a water softener/conditioner for hardness”. While this method will work, it does add considerable initial cost to the customer as well as increased service fees. Some dealers will use air injectors, chlorine, ozone, sand, greensand, birm, carbon, or a series of mechanical filters as well as softeners and acid neutralizers to correct an iron problem. The equipment we employ depends on your water test results. After we get the test results, we will then recommend a system that will correct your problem and one that you will be satisfied with.
