Watch this quick video for a better understanding of how ion exchange can remove iron from water. Instead, they simply call it, a water softener.Ī water softener is simply a system that runs your water through a bed of ion exchange resin that removes hard minerals and also iron. Most people are familiar with the process of ion exchange, they just don’t know it. The most economical way to remove this dissolved iron from your water is by the use of ion exchange. Once the water has passed through the 5-micron filter cartridge, there may still be some finer particles of iron in your water, or dissolved (Ferrous) iron. Providing that the water pressure in your home is adequate, using a 5-micron water filter cartridge in your whole house filter housing will remove a great deal of non-dissolved (Ferric) iron from your water.Ī 5-micron water filter cartridge is fine enough to be very effective at filtering out iron particles from your water, yet it is not so dense as to significantly reduce the water pressure in an average home. For the average home, this means the use of a large whole house filtering system. What kind of iron is making your water orange, and how to remove it from your water?īoth Ferrous (dissolved) and Ferric (non-dissolved) iron can cause an orange color in your water, but because they are present in the water in different ways, they need to be removed by different methods.įerric (non-dissolved) iron in water is iron that is in a large particle form and therefore a large amount of Ferric iron can be removed by fine mesh filtration. Although both forms of iron can make your water appear orange, they need to be removed from the water in different ways. Water from a private well can contain both Ferric iron (iron particles that are not dissolved in the water) and Ferrous iron (iron that has been dissolved in the water). The more exposure the water has to the iron deposits, the more potential iron that the water can absorb, and the more orange coloring you will see in the water. Well, water can often contain iron that it has absorbed as it traveled through the iron deposits in the earth. Report this adWhen chlorine comes into contact with exposed iron, it can more easily corrode the iron and carry it in the water to your home.Īlso, the chlorine will cause iron to come out of solution which means that the Ferrous iron that may be dissolved in the water will become non-dissolved, (Ferric) iron which is more visible than dissolved ferrous iron which can make the water appear orange. Municipal water suppliers will often flush out there pipes and may introduce high amounts of chlorine into the water to disinfect the inside of the piping. ![]() Iron pipes or changes in the water that the municipal supplier is getting its water from may mean iron in your municipal water.Ī cracked or damaged pipe may allow corroded iron to be exposed to the water, and therefore iron may get into the water. Most municipal water supplies will be free of iron, but that doesn’t mean that there can’t be occasional orange water because of iron contained in the water. Where is the iron coming from? Orange water from municipal water: ![]() If you would like to get all of the scientific details about why rust comes in different colors, you will have to understand Crystal field theory which explains how iron breaks down in different ways which makes it into different colors. Rather than getting into the complicated science of it all, the orange too orange-brown color that we most commonly see in the water is that color because of the amount of iron that is in the water and the chemical composition of the iron. The actual color that the iron oxide becomes can vary from a light yellow, too orange, brown, and even green. The orange color that we see in water that contains iron is the iron oxide or rust that has been created from the iron reacting with oxygen and water. ![]() Why does iron make your water look orange?
