Ferrous iron
Ferrous iron, also known as dissolved or clear water iron, is soluble iron that when dissolved in water is invisible to the naked eye. However, once the water you use evaporates from your shower or kitchen sink, that iron will stain your home and be difficult to clean. This type of iron can be removed from your water with a water softener, but you must take care to use iron cleaning agents when regenerating your softener, or else the resin will become coated with iron and have less capacity to remove iron or hardness. Depending on water chemistry, this type of iron may be best removed by first oxidizing it into ferric iron and then removing it with advanced oxidation systems from Penguin Water.
Ferric iron
Ferric iron, also known as particulate or red water iron, is insoluble iron in suspension in water. This type of iron has been oxidized and cannot be removed through a water softener. Special kinds of media like greensand or BIRM can be used to remove this type of iron, and large particles can often be caught in simple depth filters. For most well water customers, we recommend using advanced oxidation systems before treating water with a softener.
Organically bound iron
Iron bacteria
Some kinds of bacteria consume dissolved iron for fuel and produce gels and slimes, in addition to bad odors and tastes. These slimes can often be found in toilet tanks. While not harmful to human health, the effects of foul smelling and tasting water with staining slimes are certainly unpleasant. Iron bacteria can be removed with the advanced oxidation systems from Penguin Water.
