Introduction
Welcome to our comprehensive guide on how to get iron out of well water. If you are one of the many homeowners who rely on well water for your daily needs, you may have noticed that your water has a metallic taste or leaves rust-colored stains on your fixtures and clothing. This can be a common problem with well water, as it often contains high levels of iron. In this guide, we will explain the causes of high iron levels in well water, the effects of iron in water, and most importantly, how to remove iron from well water once and for all.
Why Does Well Water Contain Iron?
Groundwater is naturally exposed to minerals and rocks, which can lead to high levels of iron content. Additionally, contaminated surface water can seep into the well and cause water to have high levels of iron. The amount of iron in your well water can vary depending on the location and geology of the well.
Iron in well water is commonly found in two forms: ferrous (soluble) iron and ferric (insoluble) iron. Ferrous iron dissolves in water and is not visible, while ferric iron is visible as red or brown rust-colored stains and can leave unwanted residue on your fixtures and laundry.
While iron in well water is not harmful, it can be an eyesore and leave stains on your dishes and fixtures. The good news is that there are several ways to remove iron from well water. In the following sections, we’ll explain the most effective methods.
How to Get Iron Out of Well Water
1. Water Softeners
A water softener system works by removing iron from water through a process called ion exchange. The system removes dissolved iron and replaces it with sodium or potassium ions, which do not cause staining or buildup on fixtures. Water softeners are an effective way to remove moderate iron levels and are best suited for households with low to moderate water usage.
2. Oxidation Filters
Oxidation filters use a media such as manganese dioxide to chemically react with iron and turn it into a solid particle that can then be filtered out. These filters are effective at removing high levels of iron but require regular backwashing to prevent clogging. Oxidation filters can also remove other contaminants such as sulfur and manganese.
3. pH Filters
pH filters increase the pH level of water by adding a neutralizing media such as calcite or magnesia. This increased pH level causes iron to precipitate out and turn into a solid, making it easier to remove through a filter. pH filters are effective at removing moderate to high levels of iron, but also require regular backwashing.
4. Chlorination Filters
Chlorination filters use chlorine to oxidize ferrous iron into ferric iron, which can be filtered out. This method is effective at removing moderate to high levels of iron, but also requires a regular injection of chlorine and can be costly and time-consuming.
5. Greensand Filters
Greensand filters use a media called glauconite, which is coated with manganese dioxide. When water passes through the filter, the glauconite media oxidizes the iron and removes it through a filter. Greensand filters are most effective at removing low to moderate levels of iron.
Advantages and Disadvantages of Removing Iron from Well Water
Advantages of Removing Iron from Well Water
1. Improved Taste and Smell: Iron in well water can cause a metallic taste and unpleasant smell. Removing iron can improve the taste and smell of your water.
2. No Stains: Iron in well water can leave rust-colored stains on your laundry and fixtures. Removing iron will eliminate these unsightly stains and save you time and money on cleaning products.
3. Longer Appliance Life: Iron in well water can cause buildup and clogs in your appliances, reducing their lifespan. Removing iron will help your appliances last longer and operate more efficiently.
Disadvantages of Removing Iron from Well Water
1. Cost: Removing iron from well water can be expensive, especially if you require a professional installation or maintenance. Some methods, such as chlorination filters, can also be costly to run and maintain.
2. Regular Maintenance: Many iron removal methods require regular maintenance, such as backwashing and media replacement. This can be time-consuming and costly.
3. Environmental Impact: Some iron removal methods, such as chlorination filters, can have negative environmental impacts. Make sure to research the environmental impact of the method you choose before installation.
