Iron Iron is not considered hazardous to health but when levels of iron in water exceeds the 0.3 mg/l limit, you can experience red, brown, or yellow staining of laundry, glassware, dishes. and household fixtures such as bathtubs and sinks. Levels exceeding 0.1 mg/l should be treated. Iron is one of the earth's most plentiful resources and makes up at least five percent of the earth's crust. When rainfall occurs it seeps through the soil dissolving iron in the earth's surface and carries it into almost every kind of natural water supply, including well water. Iron in your water can have a detrimental effect on all water processing equipment such as washers, dishwashers and other appliances.
When iron exists along with certain kinds of bacteria, problems can become even worse. Iron bacteria consume iron to survive and leave a reddish brown or yellow slime that can clog plumbing and cause an offensive odor. You may notice this slime or sludge in your toilet tank when you remove the lid. Iron can cause water to have a metallic taste and offensive odor also causing piping and fixtures to become restricted and clogged.
In addition to removing hardness, a water softener can also serve the function of removing iron. It is important when using a softener for the removal of these contaminants to minimize the oxidation potential in the water. This means keeping as little air from contacting the water as possible. If oxidizers are introduced into the stream, the iron will precipitate, making for an unfavorable environment for the ion exchange process to take place. If oxidation is significant, the recommended treatment method would be to use a filter system. In order to remove precipitated iron, a filter with at least a 5 micron rating is required. |
